1. INTRODUCTION AND BACKGROUND  
Fungal corneal ulcers, because of their poor outcomes and the lack of evidence to guide treatment, 
present a therapeutic challenge to clinicians.1 The incidence of fungal keratitis varies by region, which is 
thought to be due to differences in climate as well as risk of corneal trauma.1,2 In the tropics, fungal infection 
can account for upwards of 50% of corneal ulcers.1,3,4 In the United States fungal keratitis ranges from 35% of 
corneal ulcers in South Florida5 to 4% in temperate climates such as Los Angeles.6 The Mycotic Ulcer Treatment 
Trial I (MUTT I), a NEI-funded randomized double masked clinical trial found that natamycin is superior to 
voriconazole for the treatment of filamentous fungal ulcers and in particular for fusarium species.7 However, 
natamycin is fungistatic and has limited penetration into the corneal layers.8  
Voriconazole may still be an important adjunct in the treatment of fungal ulcers. In vitro studies suggest 
that voriconazole should have good efficacy against Aspergillus and Fusarium.9 Intrastromal injection of 
voriconazole may provide steady state drug concentrations at the site of infection and avoid intervals of sub-
theraputic drug dosing. Secondly, the identity of the organism may play an important role in guiding treatment. 
Ulcers caused by Aspergillus species did equally well with topical voriconazole and natamycin, whereas those 
caused by Fusarium species had 4 lines worse visual acuity at 3 months. Possibly, Aspergillus ulcers will fare 
better when oral voriconazole is added. Thirdly, there may be presenting characteristics, such as deep stromal 
involvement, which could predict a benefit from intrastromal voriconazole injection.  
Studies of intrastromal injection of voriconazole have yielded mixed results. Several case series have 
found intrastromal voriconazole to be beneficial.10-12 However, one randomized controlled trial, comparing 
intrastromal injection to topical voriconazole found significantly improved 3-month visual acuity in the topical 
voriconazole group.13 However, in the intrastromal voriconazole arm there were more central ulcers than in 
the topical voriconazole arm and scar size between the two groups was comparable implying that intrastromal 
injection does not lead to worse scarring. In this study we will evaluate the effectiveness of intrastromal 
voriconazole injection in addition to topical natamycin treatment for the treatment of moderate to severe 
fungal keratitis.  
Research Question: Is intrastromal injection of voriconazole beneficial in addition to topical natamycin in the 
treatment of filamentous fungal corneal ulcers? 
1.1 Specific Aims: 
1) Does the addition of intrastromal injection of voriconazole decrease the rate of repeat 3-day 
culture positivity compared with medical management? We hypothesize that there will be decreased 
3-day repeat culture positivity in the intrastromal voriconazole injection group. 
  
2) Does intrastromal injection of voriconazole improve best spectacle corrected visual acuity at 3 
months compared with medical management? We hypothesize that intrastromal injection with 
voriconazole will improve 3-month visual acuity compared with topical natamycin alone. 
 
3) Does the addition of intrastromal injection of voriconazole improve 3-month scar size, days to re-
epithelialization and rate of perforation/need for Therapeutic penetrating keratoplasty (TPK) 
compared with medical management? We hypothesize that there will be improved 3-month scar size 
and decreased perforation rate in the intrastromal voriconazole group, but no difference in days to re-
epithelialization.

Once an eye is enrolled in the study, the study coordinator will assign the study participant’s eye an ID (alpha-
numeric code) and organize the procedure in the operating room within 24 hours. Once the study participant 
has been assigned a study participant ID and randomized to treatment group, they will be included in the 
intention to treat analysis.  
3.4 Study visits 
3.4.1 Baseline Visit. During this visit, eligible patients at Pondicherry will be enrolled in the study and will give 
consent. The baseline patient form will be completed and BSCVA obtained. All study participants will begin 
topical therapy with hourly 5% natamycin immediately. They will have baseline photography and OCT. They 
will then be randomized to either intrastromal voriconazole plus natamycin or topical natamycin alone. Those 
randomized to intrastromal injection will undergo this procedure in the operating theatre within 24 hours. 
They will have an additional 2 stromal injections: one on the 3rd day and one on the 5th day. All patients will be 
admitted to the inpatient setting until the 7th day.  
3.4.2 Procedure visit. Within 24 hours of the baseline visit study participants randomized to intrastromal 
voriconazole will undergo injection in the operating theatre. They will have 2 additional rounds of intrastromal 
voriconazole injections: one on the 3rd day and one on the 5th day of the study.  
3.4.3 Day 3 visit. During this visit, study participants will have slit lamp examination and undergo repeat scraping 
and culture of the corneal ulcer. Adverse events will also be assessed and recorded. Thereafter, all additional 
treatments including but not limited to topical voriconazole, or oral ketoconazole, will be at the clinician’s 
discretion. The treating physician will remain masked to treatment arm. After the scraping and culture have 
been performed, participants randomized to receive intrastromal voriconazole injections will receive an 
additional injection of voriconazole in the operating theatre.  
3.4.5 Day 5 visit. On day 5 participants randomized to receive intrastromal voriconazole injections will receive 
their final injection of voriconazole in the operating theatre.  
3.4.6 Week 1 visit. Approximately one week from enrollment patients will undergo repeat scraping and culture. 
No other study visit information will be gathered during this visit, therefore any further examination, testing, or 
treatment will be at the discretion of the treating physician. After the Day 7th day, patients may be discharged 
from the inpatient setting. 
3.4.7 One Month visit. During this visit, study participants will have their BSCVA, slit lamp examination, and OCT 
performed during this visit. Photography will also be performed. Adverse events will be reviewed and 
recorded. 
3.4.8 Final Visit. At the 3- Month visit study participants will have their BSCVA and slit lamp examination 
recorded, in addition to repeat photography, topography and OCT and be administered the IND-VFQ. 
Endothelial cell count will also be measured. Adverse events will be reviewed and recorded.

3.6 Adverse Events (AEs) 
During each study visit, the subject will be questioned about AEs in a non-leading manner. All AEs, whether 
observed by the Investigator, elicited by the Investigator, or spontaneously reported by the subject, will be 
documented in the subject's chart and the adverse event form. Slit lamp photography will also be completed 
after any adverse event takes place.  
 
All AEs should be followed until they are resolved or until a stable clinical endpoint is reached. Each AE is to be 
classified by the Investigator as SERIOUS (SAE) or NONSERIOUS (NSAE). 
 
If a SAE occurs, the investigator at Aravind Eye Hospital, Pondicherry must fill out the serious adverse event 
form and email it to Stephen McLeod at UCSF within 24 hours of the occurrence of the SAE. The investigator 
must provide written follow-up reports until the SAE or clinically significant AE has resolved or until a stable 
clinical endpoint is reached. Notification of an SAE or clinically significant AE must also be submitted to the 
Institutional Review Board (IRB)/Ethics Committee (EC) in accordance with its requirements. All AEs must be 
reported from the time that the subject provides informed consent through the last study visit.  
4. PROCEDURES 
4.1 Masking 
All study participants will be masked to their intervention. The refractionist performing the BSCVA will also be 
masked. Due to the nature of the intervention, the surgeon and technician performing intrastromal injection 
will not be masked, however, the physician performing repeat scraping as well as the microbiologist will be 
masked to treatment arm. UCSF study personnel will not be given any identifying information.

4.3 Medical management protocol 
In the first 3 days all patients will receive hourly 5% Natamycin, 0.5% Moxifloxacin for prophylaxis every two 
hours while awake, and 2% homatropine TID. They will be randomized to intrastromal injection with 
voriconazole versus sham injection. This study requires 7 visits over 3 months including baseline visit, 
procedure visit, 3-day follow-up and procedure visit, 5-day procedure visit, 1-week follow-up, 1-month and 3-
month follow-up. After the 3-day repeat culture visit additional treatments may be added per clinician 
preference including but not limited to topical voriconazole and oral Ketoconazole. 
4.4 Procedures   
4.4.1 Corneal Gram Stain and Culture  
After patient history and slit lamp examination at the enrollment visit (Day 0), corneal scraping is performed to 
determine the eligibility of the patient (positive fungal stain and negative bacterial stain). Corneal scraping is 
recommended as standard of care for all corneal ulcer patients at the Aravind Eye Hospitals. There is a small risk to 
patients of inducing a perforation, worsening an epithelial defect, or contaminating an ulcer, and patients are duly 
informed of these risks prior to the taking of the corneal scrape.  
 
Corneal scraping will be obtained as follows:  
• 
A drop of topical anesthetic (0.5% tetracaine or 4% lidocaine) is administered to the eye to be examined.  
• 
Aseptic technique is used to obtain each corneal scrape. A flame-sterilized Kimura spatula is used, with the 
aid of slit lamp magnification, to obtain a scrape from the leading edge and base of the corneal ulcer. The 
Kimura spatula is again flame sterilized between the takings of each sample.  
• 
Two scrapings are smeared directly on to two separate glass microbiology slides for Gram stain and for KOH 
wet mount (if necessary, Giemsa or Gram Stain can be used to identify fungal elements as well). 
• 
Three further scrapings are taken and directly inoculated on to sheep’s blood agar, chocolate agar, potato 
dextrose agar or Sabouraud’s agar for bacterial and fungal culture. 
4.4.2 Intrastromal Voriconazole Injection 
The intrastromal injection will be performed in the operating theatre under the operating microscope by the 
cornea surgeon under peribulbar anesthesia and with full aseptic precautions. This will be performed within 24 
hours of the baseline visit. Voriconazole 0.5 mg/ml solution will be loaded in a 1 ml tuberculin syringe with a 
30-gauge needle. With the bevel down, the needle will be inserted obliquely starting in the adjacent uninvolved 
stroma to reach the inﬁltrate at the mid-stromal level (as the intended level for drug deposition) in each case. 
The drug is then injected and the amount of hydration of the cornea is used as a guide to assess the area 
saturated with medication. Once the desired amount of hydration is achieved, the plunger is withdrawn slightly 
to ensure discontinuation of the capillary column and thus prevent back-leakage of the drug. Four to six divided 
doses are given around the inﬁltrate/s to surround the entire circumference of the lesion.  
4.4.3 Additional Injections 
An additional two rounds of intrastromal injections will be performed at 3 days and 5 days post enrollment in 
the voriconazole injection arm only. This MUST be performed after the 3-day repeat culture visit. The study 
coordinator and treating physician will be aware of the treatment assignment; however, the follow-up 
physician and microbiologist will remain masked to treatment arm.

4.4.4 TPK 
For patients requiring TPK, the corneal button will be sent to microbiology and pathology. Patients should be 
photographed prior to surgery.  
4.5 Anterior Segment Optical Coherence Tomography Protocol 
OCT will be documented at baseline, 1 and 3 months.  The images will be captured with the Visante using 
standardized protocols by study certified ophthalmic technicians. The data will then be shared with UCSF via 
Dropbox. 
4.5.1 OCT Scan Procedures 
In order to obtain the highest quality anterior segment optical coherence tomography (OCT), the technician will 
scan the appropriate study eye according to the Visante instruction manual. 
All OCT scans will be performed in a designated diagnostic room with a uniform ambient light level. 
An initial scan of the global pachymetry will be obtained. Three scans should then be obtained at the pupillary 
geometric center on the Quad setting (4 line scans through the cornea). Subsequently, a dense scan centered 
over the area of greatest thinnest (as determined by the global pachymetry) will be performed using the Quad 
setting. Quantitative data will be obtained using the caliper function by an examiner masked to the results of 
clinical examination. 
4.5.2 Saving Scan 
• 
Save the raw images on the Visante OCT machine 
• 
Download PDF images and save to a USB drive  
o Images over the area of thinning should include the caliper measurement 
• 
De-identify images 
o Patient names or any other identifying information such as birthday should not appear within 
any of the image files.  
• 
Rename data 
o The image files will be designated with: 1) the study ID number, 2) the timing of visit  ‘1d’, “1m’, 
or ‘3m’ respectively for the 1 day, 1, and 3-month follow-up visits, and 3) image number of the 
series.  An image renamed to C101_3m_1.jpg will be the first image for eye number C101’s 3 
month follow-up visit.  An image renamed to C222_1m_3.jpg will be the third image for eye 
222’s 12 month follow-up visit.  
• 
Batch upload images to Dropbox. Procedures for uploading images to Dropbox:  
o Nagivate to Dropbox  eye’s folder  relevant study visit 
o Upload images to the eye’s relevant study visit folder 
 
5. STUDY MEDICATIONS 
The following medications will be administered for treatment purposes: Natamycin 5%, Moxifloxacin 0.5%, 
Homatropine 2%, and Voriconazole 0.5mg/ml injection.  
5.1 Treatment schedule for study medications 
In the first 3 days all patients will receive hourly 5% Natamycin drops, 0.5% Moxifloxacin drops for prophylaxis 
every two hours while awake, and 2% homatropine drops TID. The aforementioned drugs will be used for FDA 
approved indications. Study participants will then be randomized to intrastromal injection with voriconazole 
plus natamycin versus natamycin. All medications will be protected and only appropriate personnel will 
administer the drugs.

5.2 Voriconazole Dosage and Administration  
Voriconazole is an FDA approved triazole antifungal agent. The primary mode of action of voriconazole is the 
inhibition of fungal ergosterol biosynthesis by inhibiting the cytochrome P450 mediated 14 alpha-lanosterol 
demethylation. Voriconazole has demonstrated in vitro activity against Apsergillus and Fusarium species and is 
an approved treatment for serious fungal infections. Intrastromal Voriconazole injection is practice for the 
treatment of moderate to severe filamentous fungal corneal ulcers at Aravind Eye Hospital, Pondicherry.  
Voriconazole is available as 1 mg of white lyophilised powder in a glass vial (VOZOLE PF; Aurolab, India). The 
powder is reconstituted with 2 mL of lactated Ringer’s solution to a concentration of 0.5 mg/mL (50 mg/0.1 
mL). A dose of 50 mg/0.1 mL reconstituted intrastromal voriconazole is prepared just prior to administration. 
5.3 Possible Side Effects of Study Medications 
Natamycin: eye irritation, swelling, pain and/or redness, discharge 
 
Voriconazole: eye irritation, swelling, pain and/or redness, discharge

6.2 Informed Consent   
Aravind personnel will obtain full written consent from each patient. The primary surgeon will screen 
participants and determine their eligibility. He/she will clearly explain the process and risks involved and will 
also ask the patient to sign any necessary consent documents. The study participant will have 7 visits total per 
eye included in the study over 3 months; visits include hospitalization for the first 7. The patient has the ability 
to withdraw at any time and will not be forced into anything with which he/she is not comfortable.  Consent 
documents have been uploaded to the IRB application. 
 
6.3 Risks to Study Participants 
Fungal keratitis is a very serious sight threatening infection. The best therapy is still not known; therefore many 
treatments including topical and oral antifungals are often administered. Intrastromal Voriconazole injection, in 
addition to oral and topical antifungals, is current practice for the treatment of moderate to severe filamentous 
fungal corneal ulcers at Aravind Eye Hospital, Pondicherry.  Participants in the study have the same risks as 
those undergoing treatment of their fungal keratitis who choose not to participate in the study.  
It is not known whether or not the addition of oral antifungal is of benefit to these patients. The Mycotic Ulcer 
Treatment Trial II is an ongoing large prospective randomized controlled two arm clinical trial looking at 
whether or not oral voriconazole is of benefit in addition to topical antifungals. In this study we are asking 
patients to delay oral therapy for 3 days.   
As with any surgery, there are risks associated with intrastromal injection which include risk of infection, or 
damage to the cornea, which could result in vision loss. There is a very small risk of full thickness perforation 
with the needle. If this were to occur, it would most likely be self-sealing, but may increase the risk of 
endophthalmitis, a severe sight threatening intraocular infection. Sterile precautions will be taken to ensure 
decreased risk of infection.  
 
There may be some discomfort during follow-up testing (BSCVA, IOP, slit lamp, Pachymeter, Topography, and 
OCT testing and photo imaging of the eye), but this will be kept to a minimum. The participant will be asked to 
tell the doctor if any of this testing feels painful. There may be a medication reaction such as eye irritation, 
swelling, pain, redness, or discharge. If this occurs the risks of stopping the medication must be weighed against 
the severity of infection and other treatment options.  
 
6.4 Privacy, Confidentiality and Data Security  
All data will be stored and transferred using a secure server with de-identified information. 
 
We will take steps to keep the participant’s personal information confidential. Health information will be kept 
secure and separate from information which identifies participants.  Upon enrollment, participants will be 
assigned a code that will be used instead of their name, medical record number or other personally identifying 
information. Electronic files for data analysis will contain only the participant code. The code will be stored at 
Aravind on a secure server and will only be accessed by study personnel – the PI, study coordinator, or other 
member of the study team. Access to study-related patient information will be limited only to members of the 
study team. 
 
Only a small number of researchers related to this study will have direct access to the participant’s medical 
information. Paper files will be stored in locked filing cabinets in restricted access offices at Aravind. Access to 
data/specimens is restricted to study personnel. 
 
Information may be released to others outside of Aravind who are involved in coordinating or overseeing 
research, but information which identifies the participant will be kept secure. To ensure the success of this 
study, Aravind has partnered with University of California, San Francisco (UCSF)’s  F.I. Proctor Foundation, 
which is a center that specializes in ophthalmology research. The coordinating center at UCSF will have access 
to de-identified information using a code number. UCSF’s role is to support Aravind on the data analysis

portion of this study and assisting with the development of consent and study-related materials. UCSF will 
obtain IRB approval to take part in this study (IRB number: 15-17347). 
 
6.5 Exclusion of Vulnerable Populations 
The following populations will not be enrolled in this study: children (18 years and under), pregnant women, 
decisionally impaired adults, and prisoners. 
 
6.6 Compensation to Participants 
There is no additional cost or compensation for the study participant. There will be no compensation for 
research-related injury.  
7. DATA COLLECTION AND MANAGEMENT 
7.1 Data Collection and Entry 
All data will be collected using hardcopy patient forms at Aravind during baseline and follow-up visits. De-
identified data will be uploaded to a Dropbox account in order to share the data with the UCSF study 
coordinator. De-identified data will be input into a database using double data entry at UCSF.  
7.2 Data Consistency, Validity, and Monitoring 
Data monitoring reports will be prepared using STATA and Excel. If the forms are not filled out 
completely, the UCSF study coordinator will contact the person responsible for completing the form to provide 
the missing data, or clarify any inconsistent data. The Aravind study coordinator is the only person who is 
authorized to add missing data or make any changes to the study forms.  All changes should be made with a red 
ink pen, and then signed and dated. 
7.3 Data Storage and Security 
De-identified data will then be input into a database using double data entry at UCSF. Data will be stored at 
UCSF for about 10 years.
