The impact of the first peak of the COVID-19 pandemic on childhood myopia control practice patterns among ophthalmologists-an international pediatric ophthalmology and strabismus council global perspective.

BACKGROUND: The prevalence of myopia keeps increasing during the COVID-19 pandemic. We aimed to map the worldwide treatment preferences of ophthalmologists managing myopia control during the first wave of the pandemic. METHODS: An online questionnaire inquiring about pharmacological and optical treatment patterns during the first half of 2020 was sent to pediatric ophthalmology as well as general ophthalmology memberships worldwide. The results among pediatric ophthalmologists were compared to a previous study we performed before the pandemic. RESULTS: A total of 2269 respondents from 94 countries were included. Most respondents were pediatric ophthalmologists (64.6%), followed by ophthalmologists from other subspecialties (32.3%). The preferred modality for all geographical regions was a combination therapy of pharmacological and optical treatments. When evaluated independently, the pharmacological treatment was more popular than the optical treatment in most regions other than East Asia (P < 0.001). Compared to a pre-pandemic questionnaire, the participation of pediatric ophthalmologists affiliated with non-university hospitals increased. Additionally, the prevalence of respondents utilizing either any type of pharmacological treatment and those that using only evidence-based treatments increased globally. Although a decline in the use of optical treatment was evident worldwide, the use of evidence-based optical treatments increased. CONCLUSION: Ophthalmologists around the world preferred a combination therapy of pharmacological and optical treatments. More pediatric ophthalmologists treated myopia progression and preferred a better evidence-based approach to control myopia. These trends reflect a positive response and more awareness of the rising prevalence of myopia due to the increased burden of myopia imposed by the COVID-19 pandemic.

Keratoconus International Consortium (KIC)- advancing keratoconus research.

CLINICAL RELEVANCE: The Keratoconus International Consortium (KIC) will allow better understanding of keratoconus. BACKGROUND: Keratoconus is a disorder characterised by corneal elevation and thinning, leading to reduced vision. The current gaps in understanding of this disease will be discussed and the need for a multi-pronged and multi-centre engagement to enhance our understanding of keratoconus will be highlighted. DESIGN: KIC has been established to address the gaps in our understanding of keratoconus with the aim of collecting baseline as well as longitudinal data on several fields. PARTICIPANTS: Keratoconus and control (no corneal condition) subjects from different sites globally will be recruited in the study. METHODS: KIC collects data using an online, secure database, which enables standardised data collection at member sites. Data fields collected include medical history, clinical features, quality of life and economic burden questionnaires and possible genetic sample collection from patients of different ethnicities across different geographical locations. RESULTS: There are currently 40 Australian and international clinics or hospital departments who have joined the KIC. Baseline data has so far been collected on 1130 keratoconus patients and indicates a median age of 29.70 years with 61% being male. A total of 15.3% report a positive family history of keratoconus and 57.7% self-report a history of frequent eye rubbing. CONCLUSION: The strength of this consortium is its international, collaborative design and use of a common data collection tool. Inclusion and analyses of cross-sectional and longitudinal data will help answer many questions that remain in keratoconus, including factors affecting progression and treatment outcomes.

Efficacy of an Automated Algorithm for Screening Diabetic Retinopathy in Gradable and Ungradable Images in Real-Time Conditions.

Background: To examine the effectiveness of a computer-assisted device (CAD) for diabetic retinopathy (DR) screening from retinal photographs at a vitreoretinal outpatient department (VR OPD), telecamps, and diabetes outpatient clinic by an ophthalmologist. In particular, the effectiveness of CAD in gradable and ungradable retinal images was examined. Methods: A total of 848 eyes of 485 patients underwent 45° retinal photographs at the VR OPD of a tertiary care hospital in southern India. A total of 939 eyes of 472 patients with diabetes were examined in the telecamps conducted in remote villages in Tamil Nadu, a state in southern India. A total of 2,526 eyes of 1,263 patients were examined in a diabetes clinic using 45° field retinal photographs. The algorithm was validated under physiological dilatation (without pharmacological dilatation) in all three arms. Results: Seventy-one percent of 848 eyes in VR OPD, 13% of 939 eyes in telecamps, and 7% of 2,526 eyes in diabetes clinic were diagnosed to have DR. The algorithm showed 78.3% sensitivity and 55.1% specificity for all images and 78.9% sensitivity and 56.8% specificity for gradable images in the VR OPD; 80.1% sensitivity and 79.2% specificity for all images and 84.8% sensitivity and 80.0% sensitivity for gradable images in telecamps; 63.0% sensitivity and 79.6% specificity for all images and 63.2% sensitivity and 78.1% specificity for gradable images in the diabetes clinic. The algorithm had an overall accuracy of 76.4%. The ungradable rate was variable. Conclusion: The algorithm performs equally well in identifying DR from gradable and ungradable photographs and may be used for DR screening in a rural setting with limited or no access to eye care.

The application of clinical registries in ophthalmic trauma-the International Globe and Adnexal Trauma Epidemiology Study (IGATES).

Ophthalmic trauma is a leading cause of preventable monocular blindness worldwide. The prevalence of ophthalmic trauma varies considerably based on geographic location, socio-economic status, age groups, occupation, and cultural practices such as firework celebrations. Clinical registries are known to be valuable in guiding the diagnosis, management, and prognostication of complex diseases. However, there is currently a lack of a centralized international data repository for ophthalmic trauma. We draw lessons from past and existing clinical registries related to ophthalmology and propose a new suitable international multicenter clinical registry for ophthalmic trauma: the International Globe and Adnexal Trauma Epidemiology Study (IGATES). IGATES is hosted on a secure web-based platform which exhibits user-friendly smart features, an integrated Ocular Trauma Score (OTS) prognosis calculator, efficient data collection points, and schematic graphical software. IGATES currently has 37 participating centers globally. The data collected through IGATES will be primarily used to develop a more robust and improved ophthalmic trauma prognostic classification system, the Ocular Trauma Score-2 (OTS-2), which builds on previous systems such as the Birmingham Eye Trauma Terminology System (BETTS) and Ocular Trauma Score (OTS). Furthermore, IGATES will act as a springboard for further research into the epidemiology, diagnosis, and management of ophthalmic trauma. Ultimately, IGATES serves to advance the field of ophthalmic trauma and improve the care that patients with ophthalmic trauma receive.

Epidemiology and outcomes of open globe injuries: the international globe and adnexal trauma epidemiology study (IGATES).

PURPOSE: To detail the methodology for a novel ocular trauma registry and utilize the registry to determine the demographics, nature of injury, and associations of severe visual loss for open globe injuries (OGI). METHODS: Thirteen hospitals in 7 countries used International Globe and Adnexal Trauma Epidemiology Study (IGATES) platform. Patients presenting between April 2009 and 2020 with OGI (with or without) adnexal involvement or intraocular foreign body (IOFB) were included. RESULTS: Analyses of presenting and final VA, using "severe vision loss" (VA ≤ 6/60) and "no severe loss" (VA > 6/60), were performed. Four hundred fifty-four (64%) patients had VA < 6/60 at presentation and 327 (44.8%) at final follow-up, with a highly significant association between presenting and final VA (p < 0.0001). From the cohort of 746 patients, 37 were missing VA at presentation and 16 at follow-up and complete clinical data was available for 354 patients. The male to female ratio is 6:1, and mean age 36.0 ± 20.0 years old. Relative afferent pupillary defect (RAPD), zone III injury, IOFB, and eyelid injury at presentation were recorded in 50 (6.7%), 55 (7.8%), 97 (13%), and 87 (11.7%) patients, respectively, and were significantly associated with VA < 6/60 at follow-up. Older age, ≥ 61 years, was associated with 3.39 times (95% CI: 1.95-5.89) higher risk than ≤20-year-old patients (p < 0.0001) and males 0.424 times (95% CI: 0.27-0.70) lower risk than female (p = 0.0001) of severe vision loss (SVL). CONCLUSION: In OGIs from 13 hospitals, female gender, older age, zone III injury, eyelid injury, and IOFB were associated with higher risk of visual outcome of SVL.

Need for Vitreous Surgeries in Proliferative Diabetic Retinopathy in 10-Year Follow-Up: India Retinal Disease Study Group Report No. 2.

INTRODUCTION: To report the 10-year rate of vitrectomies and the associated factors in people with proliferative diabetic retinopathy (PDR) from a multicentric cohort of people with diabetes mellitus. METHODS: Ten centres in India with established vitreoretinal (VR) services for over 10 years were invited to provide long-term data on PDR. People with Type 1 or 2 diabetes with a clinical diagnosis of active PDR in 1 or both eyes were included. Baseline data collected included age, sex, duration of diabetes, source of referral and best-corrected visual acuity, and diabetic retinopathy status in both eyes. Available follow-up data included the numbers of panretinal photocoagulation (PRP) sessions, cataract surgery, treatment of diabetic macular oedema, use of anti-vascular endothelial growth factor (VEGF) therapy, vitrectomy with or without retinal surgeries over 10 years. RESULTS: Over 10 years, 89% needed supplemental PRP after initial complete PRP. One-third required retinal surgery, 16% needed intravitreal injection. Men (74.5%) had significant higher risk for vitreous (VR) surgery. Of the group with low-risk PDR, 56.8% did not require VR surgery, p < 0.001. Of the patients who underwent cataract surgery and had intravitreal anti-VEGF injections, 78.5 and 28.2% needed subsequent vitreous (VR) surgery, p = 0.006 and <0.0001, respectively. Independent predictors of need for vitreoretinal surgery included those who underwent cataract surgery and those with poor baseline visual acuity (logMAR). Eyes at lower risk for VR surgery included the eyes previously treated with PRP and low-risk PDR at baseline. CONCLUSION: Despite initial "complete" PRP, one-third of our study cohort needed vitrectomies over 10 years, highlighting that these patients require regular follow-up for a long period of time.

Impact of individual counseling on the knowledge and attitudes of type 2 diabetics regarding diabetic retinopathy: The Aditya Jyot Diabetic Retinopathy in Urban Mumbai Slums Study - Report 3.

Purpose: Baseline knowledge and attitudes regarding diabetic retinopathy (DR) have not been previously reported for type 2 diabetes mellitus adults (T2DM) in Dharavi, one of the largest slums in Mumbai. Furthermore, a pre- and post-intervention survey study regarding this topic has not been conducted to date in Dharavi. This pre- and post-intervention survey study analyzes the impacts of DR counseling sessions administered individually on the knowledge and attitudes of T2DM participants recruited from Dharavi. Methods: Potential subjects (>30 years old) from Dharavi were enrolled by community workers and screened for T2DM. Those with confirmed T2DM were each registered for an individual DR counseling session. A survey was distributed to participants before the counseling session to determine their baseline knowledge and attitudes. The same survey was distributed after the counseling session, and changes in pre- and post-survey responses were analyzed. Results: Exactly 1718 T2DM study participants were given pre- and post-surveys. Before the counseling, T2DM participants showed low baseline knowledge and attitudes regarding DR, with only 30.8% (530/1718) participants being aware that diabetes can affect the eye. Participants showed significant improvements after the counseling session, with more participants showing willingness to attend DR screenings (pre: 38.3.%, post: 56.8%; P < 0.0001) and more becoming aware that diabetes can affect the eye (90.4%, 1553/1718; P < 0.0001). Conclusion: Targeted educational interventions for T2DM individuals from the slums of western India, such as Dharavi, can lead to significant improvements in knowledge and attitudes, representing a promising avenue in tackling the burden of avoidable blindness caused by DR in India.

Choroidal Microvascular Alterations in COVID-19 Patients.

OBJECTIVE: To evaluate alterations in the choroidal angioarchitecture of COVID-19 patients using optical Coherence Tomography (OCT) based surrogate markers. METHODS: This prospective case-control study recruited 56 COVID-19 patients (111 eyes) and 61 healthy individuals (120 eyes). Choroidal thickness (CT) and Choroidal vascularity index (CVI) were derived from OCT images using a purpose-built automated software for choroidal image segmentation. A linear mixed model with age and gender as covariates was employed to compare CVI and CT between groups. RESULTS: COVID-19 patients had significantly higher subfoveal (81.3um vs 86.8um, p = .02), temporal (78.8um vs 84.3um, p = .005), nasal (87.5um vs 95.1um, p = .001) and average CT (82.5um vs 88.7um, p = .001). COVID-19 patients had significantly lower subfoveal (64.0 vs 63.5, p = .02) and average CVI (63.5 vs 63.1, p = .02). CONCLUSION: COVID-19 results in significantly thicker choroid with reduced relative vascularity. This may be attributable to increased vascular permeability secondary to inflammation, resulting in choroidal stromal edema.

Evaluation of Retinal Vascularity Index in Patients with COVID-19: A Case-Control Study.

INTRODUCTION: The purpose of this study was to evaluate the impact of COVID-19 infection on retinal microvasculature by topographically mapping the retinal arteriole-to-venule ratio (AVR). METHODS: In a comparative cross-sectional case-control study, fundus photos were obtained in COVID-19-infected patients and healthy controls. AVT was measured over 16 points across the retina using retinal vascularity index (RVI)-a novel semi-automated computerized parameter based on retinal vasculature. RESULTS: A total of 51 COVID-19-positive patients and 65 healthy controls were enrolled in the study. Overall, the mean RVI of all 16 points across the retina was 0.34 ± 0.02 in patients with COVID-19 and 0.33 ± 0.02 in control subjects (p = 0.64). Out of the 16 points being measured, three points had a statistically significant greater value in patients with COVID compared to normal controls. CONCLUSION: Localised greater RVI values were found in some of the points in COVID-19-positive patients, which likely indicates a more focal change of the vasculature.

A series of 777 pellet gun ocular injuries over a 4-month period in Kashmir.

Purpose: To examine the incidence, clinical findings and management of pellet gun-related ocular injuries that occurred during protests in Kashmir region. Methods: This retrospective study included records from 777 patients diagnosed with pellet gun-related ocular injuries admitted to a tertiary hospital in Srinagar, India, between July and November 2016. By reviewing the clinical records, the following data were collected: demographics, clinical information pertaining to the injury, imaging reports including computer tomography and ultrasonography B-scan, management in the emergency setting, and follow-up treatment. Results: Mean age was 22.3 ± 7.2 years and majority patients were male (97.7%). In terms of laterality, 94.3% and 5.7% of the patients sustained monocular and binocular injuries, respectively. In terms of the nature of injury, 76.3% of the eyes had open globe injury while 23.7% of the eyes had closed eye injury. Emergency surgical exploration was performed in 67.7% of closed globe injuries while emergency primary repair was done in 91.1% of open globe injuries. The vast majority of patients (98.7%) who required surgery underwent surgical intervention on the day of admission or the next day. Final best-corrected visual acuity (BCVA) after treatment was counting fingers or worse in 82.4% of the eyes. Conclusion: Pellet gun-related ocular injuries resulted in significant ocular morbidity, mostly manifesting as open globe injuries. Treatment often required surgical interventions, but despite expeditious management, visual prognosis remained poor for most of the patients.

Globe and Adnexal Trauma Terminology Survey.

Importance: Ocular trauma terminology should be periodically updated to enable comprehensive capturing and monitoring of ocular trauma in clinical and research settings. Objective: To update terminology for globe and adnexal trauma. Design, Setting, and Participants: A 2-round modified Delphi survey was conducted from January 1 to July 31, 2021, using an expert panel, including 69 ophthalmologists identified through their membership in ophthalmology (globe and adnexal trauma) societies. Consensus was defined as at least 67% expert agreement. A steering committee developed questions after identifying gaps in the current terminology via a targeted literature review. Round 1 sought consensus on existing and newly proposed terminology, and round 2 focused on unresolved questions from round 1. Experts included ophthalmologists who had managed, on average, 52 globe or adnexal trauma cases throughout their careers and/or published a total of 5 or more globe or adnexal trauma-related peer-reviewed articles. Main Outcomes and Measures: Expert consensus on ocular and adnexal terms. Results: A total of 69 experts participated in and completed round 1 of the survey. All 69 participants who completed round 1 were asked to complete round 2, and 58 responses were received. Consensus was reached for 18 of 25 questions (72%) in round 1 and 4 of 7 questions (57%) in round 2. Existing Birmingham Eye Trauma Terminology system terminology achieved consensus of 84% (58 of 69 experts) in round 1 and 97% (56 of 58 experts) in round 2. Experts agreed on the need for further refinement of the definition of zones of injury (55 of 69 [80%]), as the zone affected can have a substantial effect on visual and functional outcomes. There was consensus that the mechanism of injury (52 of 69 [75%]) and status of the lacrimal canaliculi (54 of 69 [78%]), nasolacrimal ducts (48 of 69 [69%]), lens (46 of 58 [80%]), retina (42 of 58 [73%]), and central and paracentral cornea (47 of 58 [81%]) be included in the revised terminology. Conclusions and Relevance: There was consensus (defined as at least 67% expert agreement) on continued use of the existing Birmingham Eye Trauma Terminology system definitions and that additional terms are required to update the current ocular trauma terminology.

Embracing technology in cataract surgical training - The way forward.

While ophthalmology as a surgical branch itself has evolved technologically with newer instruments, techniques and procedures; ophthalmic surgical training appears to have stagnated in terms of how it is delivered and how trainees' learning and performance are assessed. This collaborative editorial attempts to identify the lacunae in ophthalmic residency training and highlight how technological tools such as surgical simulators can be incorporated into ophthalmic training even in limited-resource settings with good results.

Intravitreal triamcinolone acetonide versus combined intravitreal bevacizumab and dexamethasone in diffuse diabetic macular oedema.

BACKGROUND: To compare the efficacy of a single injection of combined intravitreal dexamethasone and bevacizumab (Avastin) with that of intravitreal triamcinolone acetonide in eyes with diffuse cystoid diabetic macular oedema. DESIGN: Prospective, non-randomized, masked, interventional case series. PARTICIPANTS: Twenty-four eyes of 24 subjects with centre-involved diabetic macular oedema extending over two disc-areas with predominant cystic changes on spectral domain optical coherence tomography were selected. METHODS: Ten phakic and two pseudophakic, ocular hypertensive eyes received intravitreal dexamethasone and bevacizumab as against 12 pseudophakic, normotensive eyes that received intravitreal triamcinolone acetonide. MAIN OUTCOME MEASURES: Change in central macular volume on spectral domain optical coherence tomography and best-corrected visual acuity were measured at 6-week follow-up. RESULTS: Baseline data were matched in both groups. Post-injection central macular volume (7.46 ± 0.73 mm(3)) was significantly lower (P < 0.001) in the intravitreal triamcinolone acetonide group when compared with its pre-injection central macular volume (9.11 ± 1.0 mm(3)) or when compared with the post-injection central macular volume (P = 0.02) of the intravitreal dexamethasone and bevacizumab group (8.42 ± 1.18 mm(3)). However, post-injection best-corrected visual acuity between the intravitreal triamcinolone acetonide (0.65 ± 0.15 logMAR) and the intravitreal dexamethasone and bevacizumab groups (0.685 ± 0.15 logMAR) was not significantly different (P = 0.06) at 6 weeks. No significant correlation was noted between change in central macular volume and change in best-corrected visual acuity (r = 0.35, P = 0.07) from the pooled data of both the groups. A fair correlation was noted between change in central macular volume and pre-injection central macular volume (r = 0.55, P = 0.005). CONCLUSIONS: Intravitreal triamcinolone acetonide may be more effective than intravitreal dexamethasone and bevacizumab in reducing macular volume in patients with diffuse cystoid diabetic macular oedema. A significant reduction in macular volume does not necessarily translate into a correspondingly significant improvement in best-corrected visual acuity.

Use of offline artificial intelligence in a smartphone-based fundus camera for community screening of diabetic retinopathy.

PURPOSE: The aim of the study was to analyse the reliability of an offline artificial intelligence (AI) algorithm for community screening of diabetic retinopathy. METHODS: A total of 1378 patients with diabetes visiting public dispensaries under the administration of the Municipal Corporation of Greater Mumbai between August 2018 and September 2019 were enrolled for the study. Fundus images were captured by non-specialist operators using a smartphone-based camera covering the posterior pole, including the disc and macula, and the nasal and temporal fields. The offline AI algorithm on the smartphone marked the images as referable diabetic retinopathy (RDR) or non-RDR, which were then compared against the grading by two vitreoretinal surgeons to derive upon the sensitivity and specificity of the algorithm. RESULTS: Out of 1378 patients, gradable fundus images were obtained and analysed for 1294 patients. The sensitivity and specificity of diagnosing RDR were 100% (95% CI: 94.72-100.00%) and 89.55% (95% CI: 87.76-91.16%), respectively; the same values for any diabetic retinopathy (DR) were 89.13% (95% CI: 82.71-93.79%) and 94.43% (95% CI: 91.89-94.74%), respectively, with no false-negative results. CONCLUSION: The robustness of the offline AI algorithm was established in this study making it a reliable tool for community-based DR screening.

Ophthalmology residency trainers' perspective on standardization of residency training in India.

Purpose: The aim of this study was to study the perception of residency trainers about an optimum residency program. Methods: A survey, using a pre-validated questionnaire, was conducted by the Academic and Research Committee of the All India Ophthalmological Society, in 2019-20 with questions directed to teachers in medical colleges and national board of examination's ophthalmology residency programs on demography, teaching experience, imparting clinical and surgical skills, ideal academic schedule and dissertation in the post-graduate residency program. Results: The response rate in the survey was 47.6%. Valid responses were obtained from 309 residency trainers. Of these, 132 of 309 (42.7%) were females. The mean age was 45.3 ± 9.5 years, range 26-68 years. The trainers believed that on a scale of 0-10, clinical skills teaching should be taught, mean ± SD: slit lamp 9.8 ± 0.7; indirect ophthalmoscopy 9.3 ± 1.3; gonioscopy 9.2 ± 1.5; perimetry 8.9 ± 1.5; OCT 8.4 ± 1.9; applanation tonometry 9.5 ± 1.2 and orthoptic evaluation 8.1 (±1.9). A resident should ideally perform independently surgeries (median, inter-quartile range IQR): SICS 50 (IQR 40-100); phaco 50 (20-60); pterygium excision 20 (10-40); DCR 10 (5-20); chalazion 20 (10-50), trabeculectomy 7 (5-15); strabismus 5 (2-10), LASIK and retinal detachment 0. Ideally there should be four lectures, four seminars, four case presentations, five journal clubs and four wet labs every month. Conclusion: Teachers expected their wards to become competent professionals. There was near unanimity about the content of clinical skills training, non-medical skills and academics, but there was a significant variation on extent of surgical training that should be imparted to the residents.

New Classification for the Reporting of Complications in Retinal Detachment Surgical Trials.

IMPORTANCE: Quantifying severity of complications in rhegmatogenous retinal detachment (RRD) surgical trials is needed. A consensus classification system will help surgeons to more effectively compare harms of different surgical techniques. OBJECTIVE: To develop a new consensus-based classification to quantify severity of complications of RRD surgery. DESIGN, SETTING, AND PARTICIPANTS: A comprehensive list of complications was developed followed by a Delphi consensus survey of international vitreoretinal surgeons. The survey was conducted in 17 countries in mainland Europe, the United Kingdom, the United States, Asia, South Africa, and Australia. Seventy vitreoretinal surgeons were invited to take part in the Delphi survey; 45 agreed to participate. Participants were selected through boards/members lists of retinal societies. Data were analyzed between April 2019 and August 2019. MAIN OUTCOMES AND MEASURES: Consensus-derived classification of complications of RRD surgery, according to their severity. RESULTS: Forty-three of 45 vitreoretinal surgeons who agreed to participate in the Delphi survey completed round 1 (96%); all but 1 (98%) completed round 2. Consensus was reached for 96% of the 84 complications assessed. Examples of complications classified as least severe (graded 1) included subconjunctival hemorrhage and chemosis while those classified as most severe included endophthalmitis and sympathetic ophthalmia (graded 9) and phthisis (graded 10). CONCLUSIONS AND RELEVANCE: We propose a new classification for quantifying severity of surgical complications based on an international consensus of vitreoretinal surgeons to quantify harm and improve the reporting of complications of RRD surgery.

Reporting of Complications in Retinal Detachment Surgical Trials: A Systematic Review Using the CONSORT Extension for Harms.

IMPORTANCE: Knowledge on the frequency and severity of complications in surgical trials for rhegmatogenous retinal detachment (RRD) is essential to determine whether surgical procedures are developed and compared adequately, taking into account not only efficacy but also harms. OBJECTIVE: To review standards of reporting of complications in recent randomized clinical trials of RRD surgery. EVIDENCE REVIEW: This systematic review included randomized clinical trials on RRD surgery published between January 2008 and January 2021 in Embase, MEDLINE, and Web of Science Core Collection databases. Titles, abstracts, and full-text articles retrieved were reviewed for eligibility by 2 independent authors. Eligible studies were evaluated against checklist items from the Consolidated Standards of Reporting Trials Extension for Harms criteria by 2 independent authors, and discrepancies were resolved by discussion with a third author. FINDINGS: Fifty studies were included. The median number of checklist items fulfilled was 8 (range, 0-15), of a possible total of 18. Frequently reported items were discussions balanced with regard to efficacy and adverse events (42 studies [84%]) and inclusions of harm-associated timing of data collection (41 studies [82%]). The least frequently reported items were distinctions between expected and unexpected adverse events (1 study [2%]) and mentions of the use of a validated instrument to report adverse event severity (4 studies [8%]). Frequency of complications was commonly reported (29 studies [58%]) in contrast with complication severity (10 studies [20%]). CONCLUSIONS AND RELEVANCE: This review suggests that severity of complications of RRD surgery has been infrequently quantified and reported in randomized clinical trials and potentially represents an important area of improvement in future RRD surgical trials.

Diabetic macular edema treatment guidelines in India: All India Ophthalmological Society Diabetic Retinopathy Task Force and Vitreoretinal Society of India consensus statement.

Diabetic macular edema (DME) is a common cause of moderate visual impairment among people with diabetes. Due to the rising number of people with diabetes in India, the absolute numbers of people with DME are significant. There are several treatment options for DME, and the choice of treatment is based on the availability of retinal specialists and infrastructure for the delivery of treatment. A major challenge is the out-of-pocket expenditure incurred by patients as most treatment options are costly. Treatment also varies based on the associated ocular and systemic conditions. The All India Ophthalmology Society (AIOS) and the Vitreo-Retinal Society of India (VRSI) have developed this consensus statement of the AIOS DR task force and VRSI on practice points of DME management in India. The objective is to describe the preferred practice patterns for the management of DME considering the different presentations of DME in different clinical scenarios.

The All India Ophthalmological Society - Academic and Research Committee pan-India diabetic retinopathy project "Fixing the missing link": Prevalence data from West Bengal.

PURPOSE: The aim of this study was to determine the prevalence of diabetic retinopathy (DR) and its risk factors among diabetic patients in rural and urban West Bengal (WB). METHODS: Patients were screened in the physician's clinic by a team of ophthalmologist, optometrist and counsellor. Demographic details, diabetic control, compliance to eye checkup, awareness regarding diabetic blindness, and visual acuity were recorded using a questionnaire. DR was graded both by indirect ophthalmoscopy and fundus photo taken with a portable fundus camera. RESULTS: A total of 1553 subjects were screened over 39 camps across 14 districts of WB over 17 months. The prevalence of DR was 21.51%, with a significant difference between rural (26.55%) and urban (13.89%) areas (P < 0.01). No significant difference with gender was seen (P = 0.99). Presence and grade of DR were related to age, loss of vision, diabetic age, diabetic control, awareness of diabetic blindness and last eye checkup. CONCLUSION: This study provides the first major prevalence data from WB, and gives valuable insight regarding modifiable risk factors for DR. It is also the first DR study in India to be conducted in the physician's clinic. The study results emphasise the need to "fix the missing link" between ophthalmologists and treating physicians to win the battle against DR.
