Authors: Sujithra H , Shah Kannisha , Greeshma C 
Published: August 2023

Purpose:
To analyze the visual outcome in patients with traumatic optic neuropathy (TON) with respect to different treatment modalities, to study the correlation of initial visual loss with the final visual outcome, and to find out the predictor of final visual outcome in patients with indirect TON.

Methods:
A retrospective analysis of 36 eyes with TON was done. Data on clinical profile, including demographics, mode of trauma, best corrected visual acuity (BCVA), pupillary reflex examination, and anterior and posterior segment examination, was collected. Presence and location of orbital and cranial fractures were identified from computed tomography scan. Visual outcomes following steroid therapy, optic nerve (ON) decompression, and in untreated patients were analyzed. Pre- and post-treatment BCVA were divided into three groups based on logarithm of the minimum angle of resolution (logMAR) as follows: group A: 3, group B: 2.9–1.3, and group C<1.3. BCVA values at follow-up visits were taken as the primary outcome measure. Association between various risk factors and final visual outcome in patients with indirect TON was also analyzed.

Results:
Out of 34 patients whose 36 eyes were studied, three (8.8%) patients were females and 31 (91.2%) patients were males. Most common mode of trauma was road traffic accident (RTA; 91.2%), which was followed by fall (8.8%) and assault (2.9%). Pre- and post-treatment BCVA values of 36 eyes were compared, and improvement in BCVA after treatment was found to be statistically significant. Also, 28.6% of patients with presenting BCVA of no light perception showed improvement compared to 94.1% and 100% in groups B and C, respectively. Orbital wall fractures were seen in 80.5% (n = 29) of the patients, with lateral wall fracture being the most common (58.3%) followed by medial wall (33.3%), roof (27.7%), floor (27.7%), and optic strut (5%).

Conclusion:
Baseline BCVA had significant association with final vision improvement. Lateral wall fracture was the most common fracture associated with indirect TON. Patients treated with high-dose corticosteroids, irrespective of the time of presentation, had a better visual outcome.

Authors: Korpole Nilay Reddy , Kurada Padma , Kuzhuppilly Neetha I R , Korpole Madhukar Reddy 
Published: August 2023

Purpose:
To compare the visual outcomes and residual astigmatism following implantation of Eyecryl toric versus Alcon AcrySof IQ toric intra-ocular lenses (IOLs).

Methods:
This retrospective, observational study included 143 eyes of 141 patients who underwent phaco-emulsification, followed by implantation of Eyecryl toric IOL (n = 83 eyes) or Alcon toric IOL (n = 60 eyes) in an eye hospital in South India from 2018 to 2021. At 1 month post-op, the uncorrected distance visual acuity (UCVA), best corrected distance visual acuity (BCVA), and residual astigmatism of the toric IOL were compared and analyzed.

Results:
The mean pre-op corneal astigmatism was 2.02 ± 0.81 D and 1.70 ± 0.68 D in the Alcon and Eyecryl groups, respectively (P = 0.005). The mean post-op corneal astigmatism at 1 month was 0.50 ± 0.51 D and 0.36 ± 0.42 D in the Alcon and Eyecryl groups, respectively, with no statistically significant difference between them (P = 0.87). The mean post-op UCVA in logarithm of minimum angle of resolution (logMAR) at 1 month was similar between the groups at 0.17 ± 0.18 and 0.17 ± 0.16 in the Alcon and Eyecryl groups, respectively (P = 0.98). The mean post-op BCVA in logMAR at 1 month was 0.06 ± 0.09 and 0.03 ± 0.10 in the Alcon and Eyecryl groups, respectively (P = 0.02).

Conclusion:
Both Eyecryl toric and Alcon AcrySof IQ toric IOLs showed comparable post-operative outcomes in terms of UCVA and residual astigmatism. The post-op BCVA was clinically similar between groups but statistically better in the Eyecryl toric group.

Published: August 2023

Purpose:
To compare the slit-lamp method and wavefront aberrometry method based on outcomes of toric realignment surgeries.

Settings:
Tertiary care ophthalmic hospital.

Design:
Retrospective study.

Methods:
This study included all eyes undergoing toric intraocular lens (TIOL) realignment surgery between January 2019 and December 2021 for which TIOL axis assessment by slit-lamp method and wavefront aberrometry method was available. Data were retrieved from electronic medical records, and we documented demographics, uncorrected visual acuity (UCVA), subjective refraction, and TIOL axis by slit-lamp and wavefront aberrometry methods on postoperative day 1 and day 14. In patients with misalignment, TIOL was realigned to the original position in group 1 (27 patients) and to an axis based on calculations provided by wavefront aberrometer in group 2 (25 patients). Post-realignment surgery, UCVA, subjective refraction, and TIOL axis by slit-lamp and wavefront aberrometry methods were assessed and analyzed.

Results:
We analyzed 52 eyes and found that the mean preoperative misalignment with the slit-lamp method (44.9° ±20.0°) and wavefront aberrometry (47.1° ±19.5°) was similar. The corresponding degrees of misalignment post-TIOL repositioning surgeries were 5.2° ±5.2° (slit-lamp method) and 4.7° ±5.1° (wavefront aberrometry) (P = 0.615). Both groups showed significant improvement in median log of minimum angle of resolution (logMAR) UCVA and reduction in median refractive cylinder.

Conclusions:
Slit-lamp method is as good as wavefront aberrometer method to assess TIOL axis. Toric realignment surgery is found to be safe, and realigning TIOL based on either slit-lamp method or wavefront aberrometer method equally improved UCVA and decreased residual refractive cylinder.
What do retina fellows-in-training think about the vitreoretinal surgical simulator: A multicenter survey
Authors: Mondal Sukanya , Kelkar Aditya S , Singh Ramandeep , Jayadev Chaitra , Saravanan V R , Kelkar Jai A 
Published: August 2023

Purpose:
To profile vitreoretinal (VR) fellows-in-training from India exposed to the Eyesi surgical simulator, to identify potential barriers to voluntary use, and enumerate the most preferred tools and tasks before incorporating them into a formal skill-transfer curriculum.

Methods:
A questionnaire consisting of 22 questions was designed and circulated through an online portal (surveymonkey.com) to four different institutes of India having a VR surgical fellowship program and using a functional Eyesi (Haag–Streit) simulator. All fellows and trainees who were exposed to the simulator were eligible to participate, irrespective of time spent on the simulator and exposure to training steps on real patients. The responses collected were private and anonymous.

Results:
Of the 37 respondents, most (n = 25, 68%) considered surgical simulators to be the best training tool before operating on the human eye. A majority (n = 35, 94.5%) of participants spent <3 h per week on the simulator, which, most (n = 30, 81%) felt was not enough time. The main reasons for this underutilization were work-hour limitations (54.8%), lack of a structured training program (19.3%), or a dedicated supervisor (16.1%). Again, the majority (n = 33, 89%) of participants responded that VR surgical skills acquired during simulator training were transferrable to the operating room, which was reflected by their response (n = 31, 83.7%) that simulator-based training should be made mandatory before operating room exposure.

Conclusion:
This study gives an insight into the overall practice patterns and preferences in simulation training of surgical VR fellows-in-training across India. It indicates that the simulator is extremely helpful to fellows and if adopted, VR surgical simulators with organized, directed, and supervised sessions will considerably improve the surgical training experience.

Published: August 2023

Purpose:To describe a professionalism survey tool and its use to assess knowledge of medical professionalism in ophthalmology training programs in Central India.Settings and Design:Multi-center survey study.Methods:A validated 33-question, scenario-based survey addressing professionalism attributes was administered at five centers in central India. The attributes tested included “personal characteristics,” “physician–patient relationships,” “workplace practice and relationships,” and “socially responsible behaviors.” A mean attribute score (%) was calculated and compared to “gold standard” responses by a group of expert senior ophthalmologists (100% agreement for responses).Results:A total of 225 participants completed the survey; 124 residents, 47 fellows, and 54 consultants (98.4% response rate). The total mean attribute score was 80.7 ± 9.1 (min 16.67, max 100). There was variation in the mean attribute score by professionalism attribute (P< 0.001), and a trend toward higher mean attribute scores for consultants compared to trainees across all attribute groups. The scores for “personal characteristics” (93 ± 9.7) and “physician-patient relationship” (82 ± 15.8) were the highest, whereas scores for “socially responsible behaviors” (73.9 ± 18.6) and “workplace practices” were low (72 ± 13).Conclusions:There is a generally high level of professionalism knowledge among ophthalmologists in central India. The results suggest that experience does impact knowledge of professionalism. Potential for improvement in professionalism exists in around “workplace practices”, and around “socially responsible behaviors”. These findings may serve as a valuable discussion starter and teaching tool to enhance professionalism in ophthalmology training programs.
Preparation and uses of amniotic membrane for ocular surface reconstruction
Authors: Gera Pratik , Kasturi Nirupama , Behera Geeta , Jayasri P , Jayaseelan Jagadeeswari 
Published: August 2023

Background:
The use of human amniotic membrane transplantation is rapidly increasing for the management of various ocular surface disorders. Despite its numerous advantages, amniotic membrane is not widely available due to the lack of awareness among ophthalmologists regarding its preparation and preservation techniques.

Purpose:
To provide an instructional video demonstrating the technique of harvesting, preparation, preservation of human amniotic membrane, and its uses in the management of ocular surface diseases.

Synopsis:
The amniotic membrane is the innermost layer of the human placenta. Properties of the amniotic membrane, like the presence of various growth factors, anti-inflammatory and anti-angiogenic factors, and its low immunogenicity, contribute to its ability to promote epithelial growth and differentiation with the reduction in fibrosis during healing. To harvest amniotic membrane, informed consent is obtained from a patient undergoing an elective caesarian section, and the donor is screened to exclude the risk of infections. Under sterile precautions, the amniotic membrane is separated from the chorion and washed free of blood clots. With the epithelial surface up, the amniotic membrane is spread uniformly without folds or tears on individually sterilized 0.22 μm nitrocellulose filter papers of the required sizes. The prepared filter paper with the adherent amniotic membrane is placed in freshly prepared Dulbecco’s Modified Eagle’s Medium and stored at −80°C. The amniotic membrane can be used for surgical procedures like symblepharon release, pterygium or dermoid excision, perforated ulcers, nonhealing epithelial defects, etc.

Highlights:
Instructional videos demonstrating the preparation and preservation of amniotic membrane are very sparse. This video clearly explains how any ophthalmologist can learn to prepare and preserve the human amniotic membrane and gives a glimpse of its properties, advantages, and scope of use.

Lifting the White Walker’s curse–Management of Coats’ disease
Authors: Kelkar Aditya , Bolisetty Mounika 
Published: August 2023

Background:
Coats’ disease, described by George Coats in the early 1900s, is an idiopathic unilateral retinal vascular abnormality with exudation occurring in young males. It is characterized by retinal telangiectasia with intraretinal or subretinal exudation. Coats’ disease is mostly diagnosed in the first to the second decade of life, with a common presentation of leukocoria. Younger patients have a more severe presentation and are associated with poor visual prognosis. Management of Coats’ disease varies from observation, cryotherapy with anti-VEGFs (Vascular Endothelial Growth Factor), and surgery to enucleation. The mode of treatment depends on the age of presentation, the severity of the disease, and the stage of the disease. Through this video, we describe the clinical features, pathology, and surgical management of a 2-year-old child with grade 3B of Coats’ disease.

Purpose:
To demonstrate successful surgical management of grade 3B of Coats’ disease in a 2-year-old boy.

Synopsis:
Coats’ disease mostly presents with a diagnostic dilemma due to its varied presentation. Early detection and treatment are the keys to salvaging the eye as well as the vision, hence, avoiding dreadful complications such as neovascular glaucoma or phthisis bulbi. We demonstrate successful surgical management of a child who presented with grade 3B of Coats’ disease.

Highlights:
Through this video, we aim to describe the clinical features, pathology, and surgical management of a 2-year-old child with grade 3B of Coats’ disease. Combination of external drainage with vitrectomy, challenges faced, and the importance of visual rehabilitation postoperatively.

The Importance of Perioperative Flow Evaluation and Prevention of Steal Syndrome in Arteriovenous Fistula Surgery Using Transit-Time Flow Measurement
Authors: Colak Abdurrahim , Jalalzai Izatullah 
Published: August 2023

Aim:
Our aim is to evaluate the relationship between the survival time of arteriovenous (AV) fistula whose flows are measured with flow meter in patients with chronic renal failure who were operated for AV fistula (AVF) and present the results.

Materials and Methods:
In our clinic, we evaluated the flow meter measurement results with patency rates and usability after 6 months of AVF in 100 patients who underwent AVF operation due to chronic renal failure.

Findings:
In February 2012, transit-time flow measurement was put into use in our clinic. The last 50 consecutive patients with the same characteristics before this date constituted the control group (Group A) and the first 50 consecutive patients after this date constituted the study group. Radiocephalic fistula was made the most common (Group A, n = 50; Group B, n = 50). Nondominant upper extremity was selected when planning AVF for patients. First radiocephalic, then brachiocephalic AVF was performed. Fistulas flow was measured with an intraoperative flow meter. Those with bad flow were revised during the operation. Embolectomy was performed in one patient at the 2nd month due to fistula thrombosis, but it was not successful in one patient, and an AVF was opened with a graft.

Results:
While creating AVF, our aim is to use it effectively for a long time. By evaluating the fistula flows with the flow meter and make an intraoperative revision if necessary we ensure to extend the lifespan of a fistula.
Arteriovenous Grafts: Still a Viable Option? A 5-Year Study
Authors: Thomas Ashita Elizabeth , Desai Sanjay C , Ramswamy Chandrashekar Anagavalli 
Published: August 2023

Background:
Hemodialysis patients require a vascular access that is both reliable and long lasting. Several variables, including population changes and comorbidities, have impacted patency rates. This study analyzes multiple parameters and estimates the patency rates and complications of brachioaxillary arteriovenous (AV) prosthetic grafts used for dialysis access in a single center.

Materials and Methods:
This was a prospective single-center study conducted at the Ramaiah Medical College Hospital in Bengaluru. This study comprised 92 patients with chronic renal failure who had brachioaxillary AV prosthetic graft surgery for dialysis access between 2018 and 2022. We monitored cases for up to 2 years for complications, and the primary and secondary graft patency rates were reported.

Results:
Seventy-five percent of the participants were male, with a mean age of 60. Diseases including hypertension (72.9% prevalence), diabetes (38.2%), and coronary artery disease (20.7% prevalence) were also very common. The present investigation found that thrombosis was the most frequent problem, followed by stenosis. In this study, the primary graft patency rates after 1 year and 2 years were 60.5% and 48%, respectively, whereas the secondary graft patency rates at 1 year and 2 years were 69% and 58%, respectively.

Conclusion:
The outcomes of this study regarding graft patency and complication rates compare favorably with other published data. Therefore, the authors consider brachioaxillary AV to be the optimal HD route when no acceptable forearm veins are available for creating AV fistulas.

Published: August 2023

Background:
Health-care workers (HCWs) as frontline soldiers are involved in the war against COVID-19. Not only their protection from COVID-19 is important but also their mental health is a concern. This study aimed to measure the psychological distress among HCWs in the time of COVID-19 in Isfahan, Iran.

Materials and Methods:
A cross-sectional study was conducted in the 2nd month of the spread of COVID-19 in Isfahan, Iran (March 16 to April 3). A total of 321 HCWs participated in an online survey and answered the General Health Questionnaire, the Insomnia Severity Index, and the Medical Outcomes Study Social Support Survey. t-test and ANOVA were used for comparing variables between groups. Multiple linear regression was used to evaluate the predictive factors of psychological distress.

Results:
About 34% of our HCWs suffer from some levels of psychological distress. The result of multiple linear regression (R
2: 0.41) shows that the predictive variables with the highest value were insomnia, working as a medical resident, and lack of social support (standardized coefficient of beta: 0.51, 0.25, and 0.16, respectively; P < 0.05).

Conclusion:
The result of our study shows that about one-third of HCWs in COVID-19 special hospitals have some psychological problems. Being a medical resident, suffering from insomnia, and lack of social support are predictive variables.
Transcultural adaptation and validation of the Persian version of the Brief Emotional Intelligence Scale
Authors: Hadadian-Chaghaei Fateme , Haghani Fariba , Feizi Awat , Taleghani Fariba , Alimohammadi Nasrollah 
Published: August 2023

Background:
Increasing the level of emotional intelligence (EI) is seen as a strategy for improving both relational quality and efficiency at work. As of today, there was no validated Persian brief instrument for evaluating EI. To fill this gap, this article was aimed to investigate the validity and reliability of the Persian version of the Brief Emotional Intelligence Scale (BEIS-10).

Materials and Methods:
A methodological cross-sectional study was conducted among 201 Persian-speaking individuals. These individuals were selected from different parts of Iran using the convenience sampling method. Translation of the BEIS-10 was conducted by employed forward–backward method. Internal consistency was evaluated by Cronbach's α, and for test–retest reliability, the intraclass correlation coefficient (ICC) was employed. The construct validity was investigated by confirmatory factor analysis (CFA).

Results:
The Persian version of BEIS-10 indicates a good test–retest reliability (ICC = 0.612, 95% confidence interval: 0.384 and 0.769) as well as internal consistency (Cronbach's alpha = 0.748, ranging from 0.359 to 0.868 for different domains). The construct validity was evaluated by CFA and five factors from ten items were confirmed and all goodness-of-fit-indices were in acceptable levels.

Conclusion:
The article concludes that the Persian version of BEIS-10 in five factors from ten items was a reliable and valid instrument for measuring EI in the general population. As well, the article was suggesting that the Persian version of BEIS-10 may stand as a suitable alternative to time-consuming tools for EI measurement since this scale appears to be time-saving and applicable to Iranian society.
Evaluation of the predictive value of body mass index (BMI), waist circumference, and visceral fat to differentiate non-alcoholic fatty liver (NAFLD) in women with polycystic ovary syndrome
Authors: Eslami Bita , Aletaha Najmeh , Maleki-Hajiagha Arezoo , Sepidarkish Mahdi , Moini Ashraf 
Published: August 2023

Background:
Our objective was to determine the overall prevalence of nonalcoholic fatty liver disease (NAFLD) in women with polycystic ovarian syndrome (PCOS) in our sample population. The second aim was to evaluate the predictive value of body mass index (BMI), waist circumference (WC), and visceral fat for the onset of NAFLD in these patients.

Materials and Methods:
This cross-sectional study was performed on 71 women with PCOS who were referred to Arash Women's Hospital in Tehran. Demographic and clinical information and anthropometric and biomedical indices were collected by a trained nurse. Liver ultrasonography was performed for all participants by a radiologist.

Results:
NAFLD was identified in 53.5% (n = 38) of subjects and the frequency of mild, moderate, and severe grades were 65.8%, 31.6%, and 2.6%, respectively. BMI and visceral fat of patients with NAFLD were significantly higher than non-NAFLD (P < 0.001). Receiving operating characteristic (ROC) curve analysis revealed that BMI was the best indicator of predicting NAFLD (cutoff = 25.5 kg/m2, sensitivity 75%, and specificity 75%), whereas visceral fat (cutoff = 5.5%, sensitivity 79%, and specificity 67%) and WC (cutoff = 89.5 cm, sensitivity 73%, and specificity 64%) were inferior for predicting NAFLD in PCOS patients.

Conclusion:
The prevalence of NAFLD in the study population is high. Our findings supported the use of BMI as a simple and practical predictive factor for the NAFLD onset, with a cutoff level of 25.5. The use of this cutoff level will enable physicians to identify PCOS patients at risk for NAFLD.
