Full-thickness macular hole and macular telangiectasia in a child with Coats' disease.

A 9-year-old boy presented with a 6-month history of decreased vision in his left eye. The patient's retinal examination was significant for telangiectatic vessels involving the posterior pole and the superior and inferior post-equatorial regions, circinate intraretinal exudation at the macula, and a full-thickness macular hole that was confirmed by optical coherence tomography. Chronic exudation from the anomalous vessels may be involved in the pathogenesis. Full-thickness macular hole formation may occur in conjunction with Coats' disease in children, which has not been reported to date, to the best of the authors' knowledge.
