PURPOSE: To study the clinical profile, treatment, and visual outcome of patients with Coats disease in India. METHODS: This was a cross-sectional, observational hospital-based study of patients diagnosed with Coats disease during a 10-year period using an electronic medical record system. RESULTS: We identified 675 patients with Coats disease with a prevalence rate of 0.025%. The mean age of the patients was 16.8 years (median, 12 years). Majority were males (75%) with unilateral presentation (98%) in first decade of life (n = 309, 46%). The most common presentation was foveal exudation (stage 2B, n = 161, 23.3%), followed by exudative retinal detachment-extrafoveal (stage 3A1, n = 143, 20.7%), and extrafoveal exudation (stage 2A, n = 136, 19.7%). Treatment modalities included observation (48 eyes, 17%), laser photocoagulation ± intravitreal bevacizumab/triamcinolone acetonide (n = 82, 29%), cryotherapy ± intravitreal bevacizumab/triamcinolone acetonide (n = 64, 23%), and surgical intervention (n = 86, 31%). Despite appropriate treatment, at mean follow-up of 16 months, there was no significant difference between presenting and final visual acuity (48% vs. 48%, p > 0.05). Using multivariate regression analysis, factors associated with poor visual outcome were younger age (< 0.001; - 0.02 to - 0.1), unilateral disease (0.04; - 0.68 to - 0.01), cataract (0.004; 0.13 to 0.69), retinal detachment (< 0.001; 0.49 to 0.82), and glaucoma (< 0.001; 0.34 to 0.94). CONCLUSION: The most common clinical presentation of Coats disease in India is foveal exudation in first and second decade. At initial presentation, about half of the affected eyes had blindness and one-third underwent surgical intervention.
