Coats Disease in 9 Patients: A Hispanic Case Series

Abstract

Background/Aim To describe demographic and clinical characteristics, treatment, and visual prognosis of Coats disease in Hispanic patients. Methods A retrospective chart review was performed on nine patients (ten eyes) diagnosed with Coats disease in our two clinical centrers from 2004 – 2017. Results Mean age at diagnosis was 5.5 years (range 1 – 12 years) and mean follow-up time was 48 months (range 9 – 108 months). Eight patients (89%) were male and had unilateral disease and one (11%) female patient had bilateral disease. In 40% of the cases, patients were asymptomatic. Visual acuity at first presentation was worse than hand motion in 60% of the eyes. Half of the eyes (5/10 eyes, 50%) had exudative retinal detachment (≥ stage IIIA). Vascular ablation with cryotherapy combined with retinal photocoagulation was the most frequent therapeutic approach (40%). Despite anatomical success at 6 months in 100% of the treated eyes, visual outcome at 1 year of treatment was poor (worse than 20/200) in 70% of the cases. Conclusions In our case series, patients were mostly asymptomatic on presentation, with severe stages of Coats disease. Even with anatomical success after surgical treatment in all treated cases, long-term visual prognosis remained very limited.
