Advanced Coats' disease: Treating the effect before the cause

An 8-year-old child with Stage 3A Coats' disease and severe submacular lipid exudation was initially treated with intravitreal injections of bevacizumab followed by triamcinolone. The exudative retinal detachment was then treated by scleral buckling, cryotherapy of persistent telangiectasia, and subretinal fluid drainage. The residual telangiectasia on the reattached retina was finally ablated by photocoagulation. The patient had a near-total resolution of submacular hard exudates without macular fibrosis. The peripheral telangiectasia and exudative detachment also regressed, with the sustained recovery of excellent visual acuity.
