Brief summary:
PURPOSE: Scleral buckle surgery is a widely used ophthalmic surgery for the correction of rhegmatogenous retinal detachment. Studies suggest that eye pain is a common and underestimated occurrence after scleral buckle surgery, but as of yet, there is no definitive management method for reducing pain following scleral buckle surgery. The investigators aim to control pain following scleral buckle surgery with sub-tenon's irrigation with triamcinolone acetonide at the time of surgery. Using a randomized prospective clinical study, the investigators test if this technique will reduce the pain, nausea/vomiting, and analgesic use caused by scleral buckle surgery.

METHODS: Forty-eight patients undergoing scleral buckle surgery will be randomized into two groups. The experimental group receives a sub-tenon irrigation of 1 cc 40mg/mL triamcinolone acetonide around the base of the scleral buckle (0.25 cc in each quadrant) at time of operation. The control group does not receive any triamcinolone irrigation. Pain scores are measured 1 day post-operatively via 11-pt numerical rating scale as the primary outcome. The nausea/vomiting score is measured 1 day post-operatively via standard 6-pt scale. Patients track pain medication use via pill count. Values will be measured again at 1-2-week and 6 months post-op.

3.0 
Background 
3.1 Summarize the relevant prior research on this topic and gaps in current 
knowledge within the field of study. 
Scleral buckle surgery is a widely used ophthalmic surgery for the 
correction of primary rhegmatogenous retinal detachment. Research 
suggests that it is of equal efficacy as pars plana vitrectomy and that most 
eyes retain visual acuity for 20 years after surgery. Studies also suggest 
that eye pain is a common and underestimated occurrence after 
vitreoretinal surgery for retinal detachment, with 56% of patients reporting 
intense pain post-operatively. Levels of post-operative nausea were also 
correlated to the level of pain experienced.1 In a study on chronic pain 
following scleral buckle surgery, it was shown that all patients 


Using Triamcinolone Acetonide to Reduce Pain after Scleral Buckle Surgery 
VT Research Protocol version 1.0.0 
Page 5 of 26 
Revised: February 9, 2019 
experienced pain following the surgery, with a wide range of subject pain 
scores. 18% of these patients experienced chronic pain for >6 months 
following surgery. Patients who experienced chronic pain showed higher 
pain scores in the immediate post-operative period.2 Local inflammation 
has been shown to be associated with eye pain in the first few days after 
surgery.1 It has also been shown that reduction of swelling following 
scleral buckle surgery reduces pain following surgery.3 Triamcinolone 
acetonide is a corticosteroid that is used extensively in ophthalmology for 
many indications including uveitis, vasculitis, proliferative 
vitreoretinopathy, macular degeneration, and macular edema. 
Triamcinolone works by inhibiting phospholipase A2 induction, and 
thereby downregulating inflammatory mediators including interleukins, 
prostaglandins and tumor necrosis factor. Corticosteroids also have been 
shown to have profound anti-angiogenic effects, vasoconstrictive effects, 
anti-permeability effects, ability to help maintain blood-retinal barrier, and 
facilitation of exudate reabsorption. Furthermore, triamcinolone has 
relatively small particles, allowing it to be injected in or around the eye, 
and has a duration of action of several months.4 Surgery in and around the 
eye has been shown to cause intraocular inflammation, called uveitis. 
Corticosteroids are currently the cornerstone of treatment for uveitis. A 
study of perioperative intravitreal injection of triamcinolone during pars 
plana vitrectomy for open globe trauma demonstrated a improvement in 
visual acuity, likely due to the anti-inflammatory effects of triamcinolone.5 
Another study using triamcinolone with bupivacaine as a peribulbar 
injection at the conclusion of surgery for retinal detachment demonstrated 
a reduction in the use of hydrocodone following surgery, and 
demonstrated a trend of reduced pain, though it did not reach full 
significance.6 As of yet, there is no definitive management method for 
reducing pain and swelling following scleral buckle surgery. We will be 
employing a sub-tenon irrigation approach to deliver 1cc of 40 mg / mL 
triamcinolone directly on the sutured area to reduce pain following surgery 
to try to address this gap. 
 
3.2 Describe any relevant preliminary data 
The use of Triamcinolone Acetonide sub-tenon irrigation has been done as 
standard at Vistar for scleral buckle surgeries for the last 2 years by Dr. 
Vishak John and Dr. Michael McClintock. Observations by the two 
surgeons suggest that there is a great analgesic effect for patients 24 hours 
post-surgically when compared to patients not given TA. There have been 
no noted adverse effects resulting from this use.  
3.3 Based on the existing literature, provide the scientific or scholarly 
rationale for and significance of your research and how will it add to 
existing knowledge.

Currently, there does not appear to be any definitive standard of care for 
reduction of post-operative pain and swelling following scleral buckle 
surgery, as demonstrated by the wide variety of techniques employed.7 
Multiple Vistar surgeons currently use Triamcinolone Acetonide for all 
scleral buckle surgeries within the system, but this practice has not yet 
been proven in a randomized control trial. Some physicians are 
prescribing opioids to control pain following scleral buckle surgery6; in 
today’s environment of opioid crises, this is something we would like to 
avoid. The significance of this study is that if the outcome is positive, it 
will help to determine a definitive standard of care for reducing pain and 
swelling following scleral buckle surgery that will allow reduced 
prescription of narcotics.

Procedures Involved 
8.1 Describe and explain the study design. 
Randomized Control Trial. Subjects will be patients at Vistar Eye Center 
who are undergoing scleral buckle surgery for rhegmatogenous retinal 
detachment. Patients of this indication will be consented and enrolled in 
the trial as detailed in section 24, and randomized (by coin-flip) into one 
of two arms, the control or the experimental. Patients in both arms of the 
study will be screened for IOP via handheld digital tonometry (tonopen) 
and will undergo standard scleral buckle procedures, including irrigation 
with 1 ml .75% Marcaine for local anesthesia (as is standard for all 
surgeries). At time of surgery, patients in the experimental group will 
receive irrigation of 1 ml (40 mg/mL) triamcinolone around the bed of 
applied scleral buckle distributed equally in all 4 quadrants (.25 ml per 
quadrant) under the tenon layer of the eye. Patients in the control group 
will be given irrigation around the applied scleral buckle of 1 ml balanced 
salt solution instead of triamcinolone. Patients will be masked to the 
treatment group assignment. The surgeon cannot be masked, as the 
triamcinolone solution is white and the balanced salt solution is clear. 
Intraoperative details will be recorded in the EMR about the surgery in 
both groups, including duration of surgery, time of irrigation, any 
additional pharmaceuticals or anesthesia applied, procedures performed, 
and placement of the buckle. Patient will receive a pill-count form at the 
end of the visit to keep track of rescue analgesic consumption. All patients 


Using Triamcinolone Acetonide to Reduce Pain after Scleral Buckle Surgery 
VT Research Protocol version 1.0.0 
Page 9 of 26 
Revised: February 9, 2019 
will be given appointments for post-operative day 1, and 1-2 weeks post-
operative as is standard practice.  
On post-operative day one, primary outcome data will be obtained by a 
blinded examiner who will be giving the patient a form which asks about 
the patient’s pain score by reference to an 11-point numbered rating scale 
(0-10). On the same form, patients will also be asked about post-operative 
nausea and vomiting for secondary endpoint, which will be scored from 0-
6 by adding the points for question II and question III from the pain and 
nausea survery8. The form will be collected by the same examiner when 
completed. Pill count sheet will be collected and additional sheet will be 
given for patient to track analgesic use between first and second visit. 
Patient will then have regularly scheduled visit with the surgeon who will 
be screening the patient for success of surgery, adverse events, and will 
examine pain and nausea scores to ensure both are well controlled. The 
physician will be ensuring the patient’s safety, and will be allowed to 
prescribe any medications deemed medically necessary for control of side 
effects, nausea, and pain. IOP of all patients will also be measured at this 
visit.  
At second post-operative visit (1-2 weeks), patients’ IOP will be measured 
again for safety endpoint. Patient pill count sheet will be collected. 
Patients will be filling out 11-point NRS pain score and post-operative 
nausea and vomiting sheet again during office visit and it will be collected 
by blinded examiner. Patient will then be examined by surgeon again for 
success of surgery, adverse events, and control of pain and nausea.

8.2 Describe: 
● 
Procedures or safeguards intended to reduce the probability and 
magnitude of risks. 
 
Patients will be screened twice for IOP (measured by tonometer) 
post-surgically to check for ocular hypertension. Patients eyes will 
also be examined at both visits by the primary surgeon via slit-lamp 
to determine any adverse events as a result of surgery or the 
intervention. The surgeon is responsible for the medical safety of all 
patients and may prescribe any medications deemed necessary for 
control of side effects of surgery or intervention, including nausea 
and vomiting.

screen for enrollment, and the number of subjects you will need to 
complete the research procedures. 
n/a 
14.4 If the study has more than one procedure, indicate the total number of 
subjects to undergo each procedure separately. 
n/a 
15.0 Recruitment Methods 
15.1 Describe when, where, and how you will recruit potential subjects. 
Subjects will be recruited in the physician’s office at Vistar Eye Center at 
time of surgery scheduling via the recruitment script attached. The 
surgeon (VJ, MM) or research coordinator (PV) will be recruiting the 
patients as they are the most familiar with the patient’s medical history, 
potential drug complications, and have the best ability to address medical 
questions.  
15.2 Describe the source of subjects (for example, clinic patients with specific 
conditions, students in the library, community members at a gathering, or 
members of a local gym). 
Patients with rhegmatogenous retinal detachment with indication for 
scleral buckle surgery at Vistar Eye Center  
15.3 Describe the methods that you will use to identify potential subjects. 
All patients who present with indication for scleral buckle surgery are 
considered potential subjects. 
15.4 Describe materials that you will be use to recruit subjects. Attach copies 
of these documents with this protocol in Protocol Management and be 
sure to include the IRB protocol number on each document.  
Recruitment script can be found attached. 
● Describe any compensation to subjects. Separate compensation into 
appropriate categories, such as: reimbursement for expenses, time and 
effort, and additional incentives for study participation.  For each 
category, specify the amount (including any pro-rated amount), schedule, 
and method of payment. 
● $20 total compensation for completion of the study (will be disbursed after 
6 month follow-up phone call) 
 
16.0 Withdrawal of Subjects 
16.1 Describe circumstances under which you anticipate subjects could be 
withdrawn from the research without their consent. 


Using Triamcinolone Acetonide to Reduce Pain after Scleral Buckle Surgery 
VT Research Protocol version 1.0.0 
Page 16 of 26 
Revised: February 9, 2019 
• The research is canceled by the FDA or the sponsor 
• Patient is unable to keep scheduled appointments  
• A patient has a side effect that requires stopping the research 
16.2 If applicable, describe any procedures for orderly termination (e.g., 
discontinuation of a study drug or debriefing after a behavioral 
intervention). 
N/A 
16.3 Describe procedures that you will follow when subjects withdraw from the 
research, including partial withdrawal from procedures with continued 
data collection (e.g., participant declines to continue with regular blood 
draws, but continues with periodic behavioral questionnaires). 
If the patient withdraws consent to study before the time of surgery, the 
patient will not receive either the experimental or control treatments, and 
will receive standard surgical treatment. The patient’s data will not be 
extracted from the EMR for study purposes, and the patient will not be 
given any of the survey materials. If a patient withdraws consent after the 
surgery, the patient’s data will not be extracted from the EMR for analysis 
and the patient will be given no further survey materials. Existing survey 
materials will be destroyed. If patient partially withdraws from procedures 
after surgery, the data may be used except for that which is not completed. 
17.0 Risks to Subjects 
17.1 List the reasonably foreseeable risks, discomforts, hazards, or 
inconveniences to the subjects related the subjects’ participation in the 
research.  
Adverse event data was collected by the FDA from 300 published 
articles containing data from controlled and uncontrolled clinical trials 
which evaluated over 14,000 eyes treated with different concentrations 
of triamcinolone acetonide. The most common dose administered within 
these trials was triamcinolone acetonide 40 mg administered as primary 
or adjunctive therapy primarily as a single injection. The most common 
reported adverse events following administration of triamcinolone 
acetonide were elevated intraocular pressure and cataract progression. 
These events have been reported to occur in 20-60% of patients. Less 
common reactions occurring in up to 2% include endophthalmitis 
(infectious and non-infectious), hypopyon, injection site reactions 
(described as blurring and transient discomfort), glaucoma, vitreous 
floaters, and detachment of retinal pigment epithelium, optic disc 
vascular disorder, eye inflammation, conjunctival hemorrhage and visual 
acuity reduced. Cases of exophthalmos have also been reported. 
Risk of infection: Corticosteroids may mask some signs of infection, 
and new infections may appear during their use. There may be decreased 
resistance and inability to localize infection when corticosteroids are 


Using Triamcinolone Acetonide to Reduce Pain after Scleral Buckle Surgery 
VT Research Protocol version 1.0.0 
Page 17 of 26 
Revised: February 9, 2019 
used. Corticosteroids may enhance the establishment of secondary 
ocular infections due to fungi or viruses. If an infection occurs during 
corticosteroid therapy, it will be promptly controlled by suitable 
antimicrobial therapy.  
Elevated Intraocular Pressure: Increases in intraocular pressure 
associated with triamcinolone acetonide injection have been observed in 
20-60% of patients. This may lead to glaucoma with possible damage to 
the optic nerve. Effects on intraocular pressure may last up to 6 months 
following injection and are usually managed by topical glaucoma 
therapy. A small percentage of patients may require aggressive non-
topical treatment. Intraocular pressure as well as perfusion of the optic 
nerve head will be monitored and managed appropriately. As our study 
will be irrigating the peribulbar space rather than injecting into the 
posterior capsule of the eye, we expect our rate of elevated IOP to be 
much lower than that determined by the FDA. 
Endophthalmitis: The rate of infectious culture positive 
endophthalmitis is 0.5%. Proper aseptic techniques will always be used 
when administering triamcinolone acetonide. In addition, patients will 
be monitored following the injection to permit early treatment should an 
infection occur.  
Cataracts: Use of corticosteroids may produce cataracts, particularly 
posterior subcapsular cataracts. As our study will be irrigating the sub-
tenon’s space rather than injecting into the posterior capsule of the eye, 
we expect our rate of cataracts to be much lower than that determined by 
the FDA. 
Patients with Ocular Herpes Simplex: Corticosteroids should be used 
cautiously in patients with ocular herpes simplex because of possible 
corneal perforation. Corticosteroids should not be used in active ocular 
herpes simplex. We will be excluding all patients with ocular herpes 
simplex. 
 
Systemic reactions are exceedingly rare in ophthalmic administration of 
corticosteroids but are included below for completeness: 
Cardiovascular: Bradycardia, cardiac arrest, cardiac arrhythmias, cardiac 
enlargement, circulatory collapse, congestive heart failure, fat embolism, 
hypertrophic cardiomyopathy in premature infants, myocardial rupture 
following recent myocardial infarction, pulmonary edema, syncope, 
tachycardia, thromboembolism, thrombophlebitis, vasculitis 
Dermatologic: Acne, allergic dermatitis, cutaneous and subcutaneous 
atrophy, dry scalp, edema, facial erythema, hyper or hypo-pigmentation, 
impaired wound healing, increased sweating, petechiae and ecchymoses, 
rash, sterile abscess, striae, suppressed reactions to skin tests, thin fragile 
skin, thinning scalp hair, urticaria

Page 18 of 26 
Revised: February 9, 2019 
Endocrine: Abnormal fat deposits, decreased carbohydrate tolerance, 
development of Cushingoid state, hirsutism, manifestations of latent 
diabetes mellitus and increased requirements for insulin or oral 
hypoglycemic agents in diabetics, menstrual irregularities, moon facies, 
secondary adrenocortical and pituitary unresponsiveness (particularly in 
times of stress, as in trauma, surgery or illness), suppression of growth in 
children 
Fluid and Electrolyte Disturbances: Potassium loss, hypokalemic 
alkalosis, sodium retention 
Gastrointestinal: Abdominal distention, elevation in serum liver 
enzymes levels (usually reversible upon discontinuation), hepatomegaly, 
hiccups, malaise, nausea, pancreatitis, peptic ulcer with possible 
perforation and hemorrhage, ulcerative esophagitis 
Metabolic: Negative nitrogen balance due to protein catabolism 
Musculoskeletal: Aseptic necrosis of femoral and humeral heads, 
charcot-like arthropathy, loss of muscle mass, muscle weakness, 
osteoporosis, pathologic fracture of long bones, steroid myopathy, 
tendon rupture, vertebral compression fractures 
Neurological: Arachnoiditis, convulsions, depression, emotional 
instability, euphoria, headache, increased intracranial pressure with 
papilledema (pseudo-tumor cerebri) usually following discontinuation of 
treatment, insomnia, meningitis, neuritis, neuropathy, 
paraparesis/paraplegia, paresthesia, sensory disturbances, vertigo 
Reproductive: Alteration in motility and number of spermatozoa. 
 
● Privacy (e.g., potential for personal information being accessed, used, 
or disclosed without the subjects’ knowledge or consent, breach of 
confidentiality/security) 
 
● In any clinical trial, there is a possibility for patient’s personal 
information being accessed improperly. This has been minimized as 
much as possible through participation in CITI training by main 
investigators, as well as not extracting patient identifying information 
from the EHR for analysis purposes.  
 
● Economic (e.g., potential for individuals to lose access to economic 
services, employment, insurability) 
● There will be no additional charge for TA treatment to the patient. 
17.2 If applicable, indicate which procedures might have risks to the subjects 
that are currently unforeseeable. This will be rare, and usually applicable 
when testing a new drug or device or a new use of an existing drug or 
device. 


Using Triamcinolone Acetonide to Reduce Pain after Scleral Buckle Surgery 
VT Research Protocol version 1.0.0 
Page 19 of 26 
Revised: February 9, 2019 
TA is a very well-studied drug that has been FDA approved since 1957 for 
ophthalmic application. It is unlikely there will be risks associated with the 
drug that have not been previously documented.  
17.3 If applicable, indicate which procedures might have risks to an embryo or 
fetus should the subject be or become pregnant. 
Triamcinolone is Pregnancy Category D, as it has been shown to increase 
rate of cleft lip in the first trimester when used systemically. It is unlikely 
to have this effect when applied locally to the eye, but some risk exists 
nonetheless. 
17.4 If applicable, describe risks to others who are not subjects (e.g., collection 
of sensitive health data that might affect sexual partners if disclosed, 
mandatory reporting of abuse, DNA testing that might affect family 
members or relationships). 
N/A 
18.0 Potential Benefits to Subjects 
18.1 Describe the potential benefits that individual subjects might experience 
from participating in the research. Include the probability, magnitude, and 
duration of the potential benefits, as this will be useful to the IRB’s 
risk:benefit analysis. Do not include benefits to society or others. These 
should be included in section 2 or 3 of this document. 
The largest benefit to subjects is the possibility to directly reduce pain 
following scleral buckle surgery. This is our primary outcome so the exact 
likelihood and magnitude are currently unknown, but likelihood is 
presumed to be high based on background literature. Magnitude is 
presumed to be around 50% reduction in pain. Subjects may also 
experience a decrease in intraocular inflammation, and post-operative 
nausea and vomiting. Furthermore, patients may have a reduced risk for 
addiction to pain medication, as we hope to demonstrate a reduced need 
for post-operative analgesics following surgery. All patients in the 
experimental group will also be receiving the treatment at no additional 
cost to them, which is a potential financial benefit. 
19.0 Data Management and Confidentiality 
19.1 Describe procedures that you will use for quality control to ensure validity 
of collected data. 
The surgeon will be including their subjective assessment of patient’s pain 
on the EHR, which they may compare to the patients written assessment 
as a form of quality control. 
19.2 Describe the steps that you will take to handle and secure study data 
during data collection, storage, use, and transmission.  Include 
information about training of study staff, authorization of access, 


Using Triamcinolone Acetonide to Reduce Pain after Scleral Buckle Surgery 
VT Research Protocol version 1.0.0 
Page 20 of 26 
Revised: February 9, 2019 
password protection, encryption, physical controls, certificates of 
confidentiality, separation of identifiers and data, etc. 
Patient data is stored securely in NextGen Electronic Medical Record at 
Vistar Eye Center according to HIPAA regulations. Data that will be 
extracted from the EMR will not contain any patient identifying 
information. The procedure by which it will be extracted is via CPT code 
records for scleral buckle surgery. De-identified data extracted will be 
stored in a dataset along with arbitrary patient ID within the Vistar Eye 
Center computer network so that it cannot be accessed without both 
physical access and log-in credentials. Access to study materials is granted 
only to 2 surgeons listed on this document (John, McClintock), and the 
research coordinator (Vaidya).  
19.3 For multi-site studies, describe how data or specimens will be handled 
and secured for each site (e.g., central or disseminated data storage, data 
coordinating center). 
19.4 Describe the plan for data disposition following the conclusion of the 
study (e.g., long term maintenance of data, data destruction methods).  
Data will not be stored outside of that needed for medical care after the 
conclusion of the study. Medical information will continue to exist on the 
Electronic Medical Records at Vistar Eye Center, but all extracted data 
will be destroyed 3 years following publication of the results of this study 
as is standard protocol. 
● 
What information will be included in the long term storage of data 
or specimens? 
● 
How long will the data or specimens be stored? 
● 
Where and how data or specimens will be stored? 
● 
Who will have access to the data or specimens during long term 
storage? 
● 
Who is responsible for receipt or transmission of the data or 
specimens? 
● 
How will data or specimens be shared or transported? 
● 
When and how will personal identifiers be destroyed? 
 
20.0 Provisions to Protect the Privacy Interests of Subjects 
20.1 Describe the steps that you will take to protect subjects’ privacy interests. 
“Privacy interest” refers to a person’s desire to place limits on with whom 
they interact or to whom they provide personal information (e.g., 
collecting the minimal amount of private information required to complete 
the study, protecting the data once it is obtained).  
No patient identifying information will be extracted from the electronic 
medical records. The only people with access to this information is the 
medical care team of the patient. De-identified data will not be shared 


Using Triamcinolone Acetonide to Reduce Pain after Scleral Buckle Surgery 
VT Research Protocol version 1.0.0 
Page 21 of 26 
Revised: February 9, 2019 
beyond the two surgeons involved in the study design and research 
coordinator. 
20.2 Describe steps that you will take to make subjects feel at ease with the 
research situation in terms of the questions being asked and the 
procedures being performed. “At ease” does not refer to physical 
discomfort, but the sense of intrusiveness a subject might experience in 
response to questions, examinations, and procedures (e.g., use of a same 
gender investigator to place sensors on the torso, a private changing area 
if clothing must be changed, sensitivity when discussing  pregnancy testing 
with subjects, making it clear on surveys that participants can discontinue 
at any time, not asking questions about private or sensitive issues unless 
necessary for the research). 
20.3 Describe how you plan to access existing sources of information about the 
subjects (e.g., medical records, grades) and how you will protect 
participant privacy through the data security plan. 
Data extraction from the medical record will be done by one of the two 
surgeon members of the Vistar Eye Center team who would otherwise 
have access to the medical data anyway for patient care. The procedure by 
which it will be extracted is via CPT code records for scleral buckle 
surgery. De-identified data extracted will be stored in a dataset along with 
arbitrary patient ID within the Vistar Eye Center computer network. 
20.4 Describe any required reporting that might occur as a result of your 
research questions, study populations, and data collection methods. 
Examples for Virginia and Virginia Tech include: 
• Any suspicions (e.g., circumstantial, disclosed) of child abuse (physical, 
emotional, sexual) and neglect  
• Sexual discrimination and/or sexual violence that involves a student 
• Disclosure or signs of intention to harm oneself (i.e., suicidal ideation 
and/or plan) 
• Disclosure or signs of desire to harm others (i.e., homicidal ideation 
and/or plan) 
• Suspected abuse, neglect or exploitation of vulnerable adults (e.g., 
individuals with a disability, elderly persons) 
 
21.0 Provisions to Monitor the Data to Ensure the Safety of Subjects 
Safety monitoring is required when research involves greater than minimal risk 
and is sometimes appropriate for other studies. 
21.1 Describe: 
● 
The plan to periodically evaluate the data collected regarding both 
harms and benefits to determine whether subjects remain safe  (e.g., 
periodic reporting to the IRB, establishing a data monitoring 


Using Triamcinolone Acetonide to Reduce Pain after Scleral Buckle Surgery 
VT Research Protocol version 1.0.0 
Page 22 of 26 
Revised: February 9, 2019 
committee, reporting data monitoring committee findings to the IRB 
and the sponsor). 
 
The patient’s IOP will be measured at baseline prior to the surgery, 
as well as 24 hrs post-op and 2 weeks post-op. This is done to 
monitor ocular hypertension, a potential side-effect of both the 
surgery and TA treatment. Patients will also have two normally 
scheduled follow-up visits with the surgeon who will be monitoring 
for any other adverse events such as hypersensitivity or infection. If 
adverse events occur that may be related to the intervention, they 
will be reported to the IRB promptly. The data will also be 
monitored after every 10th patient completes the protocol for any 
statistically significant differences in the primary or secondary safety 
endpoints. If this occurs, it too will be reported to the IRB promptly.  
 
 
22.0 Compensation for Research Related Injury 
22.1 If the research involves more than minimal risk to subjects, describe the 
available compensation in the event of research-related injury, if any. 
n/a 
22.2 Provide a copy of contract language, if any, relevant to compensation for 
research-related injury. At Virginia Tech, this is most common for 
sponsored research. 
n/a 
23.0 Economic Burden to Subjects 
23.1 Describe any costs that subjects might be responsible for because of 
participation in the research, including any uncompensated costs for items 
such as transportation, missed work, and childcare. 
None. The TA irrigation will be done at no extra cost to the patient. 
Patients do not have to make any additional visits. 
24.0 Consent Process 
24.1 Indicate the process by which you will obtain consent for study 
participation. Please upload all consent, parental permission, and assent 
forms, documents, and scripts referenced in this section to Protocol 
Management. 
Describe the following: 
● 
Where the consent process will take place (e.g., clinic waiting area, 
classroom, online) 
 


Using Triamcinolone Acetonide to Reduce Pain after Scleral Buckle Surgery 
VT Research Protocol version 1.0.0 
Page 23 of 26 
Revised: February 9, 2019 
The patient will be consented in the clinic patient exam room, 
immediately following consultation with the doctor about the 
planned surgical procedure. The consultation will be done by the 
doctor who is well trained on the procedures and risks. The doctor 
will also be able to answer any more specific questions that the 
patient may have. 
 
● 
The time interval between sharing the consent information with the 
prospective subject and obtaining consent. For lab, interview, and 
focus group studies, the Virginia Tech IRB prefers that subjects have 
at least 24 hours to review the consent form and study information 
before the appointment where consent will be obtained. For simple 
online survey studies, you can typically present the consent 
information immediately before subjects begin participation. 
 
The obtaining of consent will occur directly after the sharing of 
consent information. However, the patient will be given a copy of 
the consent forms and the surgery will not usually take place until 
the next day or longer still, giving the patient sufficient time to 
review the materials and change their decision to withdraw or 
provide consent by notifying any staff member up until the moment 
right before surgery.   
 
● 
If applicable, processes to ensure ongoing consent or assent (e.g., 
for multiple sessions; for research in which a minor will turn 18 
during the study; for longitudinal research with minors who will 
later be asked to provide or affirm their assent). 
 
As there is no more than minimal risk to the patient after the original 
intervention, we do not believe this is necessary. 
● 
Please review “SOP: Informed Consent Process for Research (HRP-
090)” for recommended procedure. Describe your process, being 
sure to include: 
o 
The name and role of all study personnel who will be trained 
and certified by the PI to conduct the consent process 
o Dr. Vishak John M.D. (PI) 
o Dr. Michael McClintock Jr. M.D. 
o Parth Vaidya, Medical Student, Research Coordinator 
o 
The time that will be devoted to the consent discussion 
The consent discussion will be given up to 15 minutes with the 
surgeon if the patient has questions or concerns about the 
study. The patient will also be given the phone number and 
email of the primary research coordinator to contact them with 
any additional questions after they leave. The patient also has 
as much time as they need to review the consent documents 
before the start of the surgery to decide to consent or not to.

Page 24 of 26 
Revised: February 9, 2019 
o 
Steps that you will take to minimize the possibility of coercion 
or undue influence 
o 
The patient will be given a copy of the consent documents and 
allowed to review them at home and change their minds about 
whether they will be consenting to the study up until time of 
surgery. Patients will also be asked teach-back questions to 
ensure adequate understanding as listed in the consent script 
document. 
o 
Steps that you will take to gauge or ensure the subjects’ 
understanding 
o 
Patients will be asked 3 questions to gauge for understanding: 
a. What is the purpose of this study? 
b. What are the risks and benefits to participating? 
c. Are you required to participate in this study? 
25.0 Process to Document Consent in Writing 
25.1 Consult “SOP: Written Documentation of Consent (HRP-091)” for 
recommended procedures, and describe whether and how consent of the 
subject will be documented in writing. 
25.2 If the research presents no more than minimal risk of harm to subjects and 
involves no procedures for which written documentation of consent is 
normally required outside of the research context, you can request that the 
IRB waive the requirement to obtain written documentation of consent 
(e.g., consent to participate is indicated by pressing a button for an online 
questionnaire – after the consent information is presented and before the 
questionnaire begins). 
25.3 If you will document consent in writing, attach a consent document with 
places for signatures. If you will obtain consent, but not document consent 
in writing, please attach the consent script or text. Review “CHECKLIST: 
Waiver of Written Documentation of Consent (HRP-411)” to ensure that 
you have provided sufficient information. You should use “TEMPLATE 
CONSENT DOCUMENT (HRP-502)”to create the consent document or 
script. 
 
26.0 Resources Available 
26.1 Describe the resources available to conduct the research. For example, as 
appropriate: 
● 
Describe the PI’s availability to supervise the research 
● 
The study was initiated by the PI (Vishak John) along with the 
research coordinator (Parth Vaidya) and another surgeon (Michael 
McClintock Jr), and the PI will take full responsibility for 
supervising the research. The PI will be fully available to answer any 
and all questions by both research team and patients. The PI will also 


Using Triamcinolone Acetonide to Reduce Pain after Scleral Buckle Surgery 
VT Research Protocol version 1.0.0 
Page 25 of 26

often be in the same physical location as the surgeons on the 
research team and the patients, ensuring access. 
 
● 
Justify the feasibility of recruiting the required number of suitable 
subjects within the agreed recruitment period. For example, how 
many potential subjects do you have access to? What percentage of 
those potential subjects do you need to recruit? 
● 
There are 4 scleral buckle surgeries done each month between the 4 
surgeons who will be conducting the operations. We would need to 
recruit 50% of them into the study in order to meet the recruitment 
period of 2 years. 
● 
Describe the time that you will devote to conducting and completing 
the research. 
This research project will not take much additional time as the 
majority of the time-consuming procedures are done anyway as 
standard of care. Additional time of 1 hour each week will be 
dedicated to consenting, answering questions, documentation, and 
statistical analysis.  
● 
Describe your process to ensure that all persons assisting with the

Each of the 2 surgeons are already well informed about the 
procedures, drugs, and risks involved due to routine retinal surgery 
training. There will be a meeting prior to beginning the study with 
the research coordinator, PI, Dr. McClintock, and all support staff 
that will be collecting the forms to ensure understanding of all 
protocols and procedures.
