Pigmentary retinal degeneration and Coats' disease: a case study

Abstract

We report a 22-year-old Hispanic man with familial congenital nystagmus, iris transillumination, and pigmentary retinal anomalies with subretinal fatty exudates similar to those seen in Coats' disease. Direct treatment of the telangiectatic vessels with cryotherapy caused a subretinal hemorrhage. We therefore recommend surrounding the area of abnormal vessels (posterior to vessels and between vessels and ora serrata) with cryotherapy to reverse the formation of the vascular anomalies.
