Spontaneous Regression of Neovascularization at the Disc in Diabetic Retinopathy

ABSTRACT

Neovascularization at the disc (NVD) is the most serious complication in diabetic retinopathy, and leads to vitreous hemorrhage and tractional retinal detachment. We report two cases of spontaneous regression of NVD in proliferative diabetic retinopathy. Two men (31 and 46 years old) with diabetes had NVD in both eyes. They were treated with panretinal photocoagulation on the left eye first, but their right eyes went untreated, because they did not revisit our clinic for several months. Fortunately, on revisit, their neovascularization had disappeared a few months later in both eyes, including their untreated right eyes. We could not find any specific causes for the spontaneous regression of the new vessels.
