Abstract
We describe the role of intravitreal anti-vascular endothelial growth factor (VEGF) agents in Coats' disease in children. In a prospective, interventional, non-randomized case series, three patients (three eyes) aged 16, seven and two years were diagnosed to have Coats' disease. In Case 1 (16 yr/ male) with macular edema, previous laser photocoagulation being unsuccessful, intravitreal pegaptanib sodium (Macugen™) was tried. Case 2 (seven yr/ male) and Case 3 (two yr/ female) were diagnosed to have Stage 4 Coats' and underwent external needle drainage, laser photocoagulation, SF6 gas injection and intravitreal injection of bevacizumab (Avastin™). Reduction of exudation and attached posterior pole (Cases 2 and 3) was seen at a follow-up of six months and two months respectively. Intravitreal anti-VEGF agents may be successfully used as adjunct treatment in select cases of Coats' disease in childhood.
