Purpose: To measure the proportion of people with major ophthalmic and retinal disorders in the tribal and non-tribal people presenting to a community eye hospital in an Indian state with a sizeable tribal population.Methods: Hospital-based cross-sectional retrospective study of all new adult patients, examined between September 2015 and June 2020. A tribal was defined as per the Indian ethnic classification. Blindness and visual impairment were defined as per the WHO standards. Diabetes and hypertension were defined as per Indian standards. The proportion of common ophthalmic and retinal disorders between the tribal and non-tribal community were compared.Results: This cohort consisted of 76,166 people (45.8%; n = 34,869, tribal); 39.4% (n = 29,989; non-tribal 23.6% and tribal 15.8%) people had ophthalmic disorders. In the examined people 2.3% were blind (higher in tribal community 4.7% versus 0.8%; P < 0.001) and 8.4% had moderate-to-severe visual impairment (higher in tribal community 14.4% versus 4.4%; P < 0.001). Refractive error (64.4%; higher in non-tribal community, 77.3% versus 44.6%, P < 0.001) and operable cataract (23.9%; higher in tribal community, 40.9% versus 11.8%, P < 0.001) were the principal ophthalmic disorders. Retinal disorders were higher in non-tribal people (5.9% vs. 2.9%; P < 0.001), but the tribal group had higher proportion of retinitis pigmentosa (20% vs. 6.4%; P < 0.001) and lower proportion of diabetic retinopathy (8% vs. 40.7%; P < 0.001).Conclusion: : The health-seeking behavior of the tribal community in India is low. A tribal person in India apparently visits the hospital when vision is grossly affected. It calls for greater advocacy, increased access to healthcare, and a larger population-based study.

Purpose: To analyze the causes for late presentation in a series of patients with advanced retinopathy of prematurity (ROP) in a tertiary eye care institute in Eastern India.Methods: We analyzed our medical records and ROP database retrospectively from 2007 to 2015 and prospectively thereafter till 2017 to identify the factors for late presentation in babies with advanced ROP (stages 4 and 5).Results: A total of 71 eligible subjects were analyzed. The mean chronological age was 15.1 months (2 months to 14 years). The three important barriers were: (1) the system and neonatal care policy failure (n = 45; 63.3%), (2) parental negligence and ignorance (n = 19; 26.7%), and (3) ophthalmologist's misdiagnosis or unavailability (n = 7; 10%). Majority of the babies (63.3%) were admitted in the neonatal care unit when they were due for ROP screening with an average duration of stay of 35.5 days.Conclusion: The main barriers to early screening for ROP were related to availability of trained human resources, ignorance of "parents and health care personnel," and distance from the point of care. This calls for training of ophthalmologists, advocacy with neonatologists and parents, and create systems for better coordination and compliance of the care providers. [ABSTRACT FROM AUTHOR]

The Retinopathy of Prematurity (ROP) epidemic is no more confined to metro cities and has spread to interior states including Eastern India. There is hardly any published data available on the subject, including the incidence and profile of babies with ROP, screening experience with binocular indirect ophthalmoscope and wide-field digital retinal imaging, as well as the difficulties faced with each model. In our cohort, 33.2% had ROP and 25.3% of babies with ROP required treatment. Mean (SD) gestational age and birth weight were 30.7 (2.53) weeks (range: 23 to 37 weeks) and 1315.09 (322.30) grams (range: 650-2500 grams), respectively. The hurdles in establishing a screening program are discussed. Binocular indirect opththalmoscopy and wide-field digital retinal imaging were complementary rather than a substitute for each other in a non-telescreening model. [ABSTRACT FROM AUTHOR]

Purpose: To describe the spectrum and demographic distribution of non-oncological retinal diseases in children and adolescents presenting to a multi-tier ophthalmic hospital network in India., Methods: This is a cross-sectional hospital-based retrospective study over nine years (March 2011-March 2020) from a pyramidal eye care network in India. The analysis included 477,954 new patients (0-21 years), collected from an International Classification of Diseases (ICD) coded electronic medical record (EMR) system. Patients with a clinical diagnosis of retinal disease (non-oncological) in at least one eye were included. Age-wise distribution of these diseases in children and adolescents was analysed., Results: In the study, 8.44% (n = 40,341) of new patients were diagnosed with non-oncological retinal pathology in at least one eye. The age group-specific distribution of retinal diseases was 47.4%, 11. 8%, 5.9%, 5.9%, 6.4%, 7.6% in infants (< 1 year), toddlers (1-2 years), early childhood (3-5 years), middle childhood (6-11 years), early adolescents (12-18 years) and late adolescents (18-21 years), respectively. 60% were male, and 70% had bilateral disease. The mean age was 9.46 ± 7.52 years. The common retinal disorders were retinopathy of prematurity (ROP, 30.5%), retinal dystrophy (19.5%; most commonly, retinitis pigmentosa), and retinal detachment (16.4%). Four-fifth of the eyes had moderate to severe visual impairment. Nearly one-sixth of patients needed low vision and rehabilitative services, and about 1 in 10 patients required surgical intervention (n = 5960, 8.6%)., Conclusion and Relevance: About 1 in 10 children and adolescents seeking eye care in our cohort had non-oncological retinal diseases; the common ones were ROP (in infants) and retinitis pigmentosa (in adolescents). This information would help future strategic planning of eye health care in the institution in pediatric and adolescent age groups., (© 2023.

Purpose : To analyse clinico-microbiological profile, antimicrobial susceptibilities, and visual prognostic factors in post-traumatic endophthalmitis (PTE). Methods : Retrospective clinico-microbiological data analysis for five years (2014-18). Prognostic factors for visual outcomes were analysed by multivariate logistic regression analysis. Results : Four hundred and eighteen patients with clinically diagnosed PTE were analysed. Culture positivity was found in 46.7% samples (44.5% vitreous, 83.3% non-vitreous). Pathogens isolated were Gram positive cocci (GPC, 49.3%, good susceptibility to vancomycin/cefazolin), Gram negative bacilli (GNB, 28.1%, <90% susceptibility to all antibiotics and 25.8% multidrug resistance), Gram positive bacilli (13.1%) and fungi (9.5%). Poor visual prognosis was associated with culture positivity, fungal or polymicrobial PTE, poor view of fundus and presence of membranes on ultrasound scans. Conclusion : GPC and GNB are the predominant pathogens in PTE, with GNB most commonly multidrug resistant. Culture positivity, polymicrobial and fungal PTE, poor view of fundus and vitreous membranes are markers of poor visual outcome.

Retinopathy of prematurity (ROP) is one of the leading causes of preventable blindness in children worldwide. Middle-income nations are currently experiencing epidemic levels of ROP, because greater access to neonatal intensive care units has improved survival rates of premature infants, but without sophisticated oxygen regulation. The epidemiology, screening infrastructure, treatment options, and challenges that these countries face are often tied to unique local socioeconomic, cultural, geopolitical, and medical factors. We present an overview and narratives of the current state of ROP in eight countries that are or soon will be experiencing ROP epidemics-India, Kenya, Mexico, Nigeria, Phillipines, Romania, Thailand, and Venezuela-with a view to fostering both an understanding of the differences in the ROP landscape in various settings and an interest in the further development of ROP screening and treatment services tailored to local requirements., (Copyright ©2019.

To describe the characteristics and treatment outcomes of an unreported, late vitreous hemorrhage due to anterior hyaloidal fibrovascular proliferation in laser-regressed retinopathy of prematurity (ROP). Interventional case series. In the ongoing Indian Twin Cities ROP study database, consecutive cases with isolated late vitreous hemorrhage at least one year after laser-regressed disease were analyzed retrospectively. Anterior hyaloidal fibrovascular proliferation was diagnosed primarily using scleral depression. Anterior retinal cryopexy with adjunctive treatments was performed. The main outcome measure was clinical resolution of new vessels with no recurrent hemorrhage over a 1-year period. Vitreous hemorrhage, at two to eight years of age, developed in three eyes of three children out of 1,168 ROP lasered eyes. All had received laser for zone I disease as neonates, with no subsequent sequelae. Evaluation revealed filiform new vessels at the posterior vitreous base involving inferior 180° with absence of any other source of hemorrhage. All underwent anterior retinal cryopexy to the affected area. Simultaneous additional treatment, based on intraoperative findings, included one case each of peripheral laser photocoagulation, lens-sparing vitrectomy and intravitreal bevacizumab. All three showed successful regression and non-recurrence of vitreous hemorrhage with improvement of vision >20/40 at an intermediate follow-up of two years. Anterior hyaloidal fibrovascular proliferation is an unreported and rare cause of vitreous hemorrhage, appearing years after laser-regressed ROP. It has a good response to interventional treatment. Meticulous scleral depression of the vitreous base under anesthesia is useful to detect this rare source of vitreous hemorrhage.
