Abstract
PURPOSE: To report on the outcome of conventional therapy in patients with Coats' disease. METHODS: Retrospective analysis of the charts of thirteen patients with Coats' disease. RESULTS: Mean age of 9 male (70%) and 4 female (30%) patients was 17.7 (range, 5-33) years; one female had bilateral disease. Eleven eyes with retinal telangiectasia and exudation were treated with argon laser photocoagulation alone or photocoagulation associated with cryotherapy; the mean follow up was 32.5 (range,17-41) years. In four eyes without foveal involvement (stage 2a) the mean presenting visual acuity (VA) remained at 0.8 or improved, whereas poor VA in seven stage 2b eyes deteriorated minimally over time. In one and two of the three eyes with total retinal detachment, phthisis or neovascular glaucoma ensued. CONCLUSION: About three decades after conventional treatment of Coats' disease stage 2a, treated eyes maintained good VA, and stage 2b eyes did not progress to advanced stages.
