Coats is an idiopathic disease related to the abnormalities in the Wnt signaling pathway during retinal angiogenesis.[1],[2] It progresses through the stages of retinal vascular anomalies, subretinal exudation, exudative retinal detachment, glaucoma, and phthisis. The patient usually is a young male with unilateral decreased vision, strabismus, or leukocoria. The importance lies in differentiating it from retinoblastoma. Treatment options range from observation, photocoagulation, cryotherapy, and intravitreal steroids to vitrectomy and subretinal fluid drainage which are rarely needed. Although the anti-vascular endothelial growth factors have been studied, their role remains inconclusive.[3],[4] In a 4-year young boy on dilatation, we uncoated the total exudative retinal detachment abutting the lens suggestive of Stage 3B of Coats disease on smartphone photography in the left eye [Figure 1].
