Choroidovitreal Neovascular Ingrowth After Photocoagulation for Proliferative Diabetic Retinopathy

Abstract
• In eight patients with proliferative diabetic retinopathy treated with focal photocoagulation for preretinal new vessels, recurrent preretinal new-vessel systems supplied from the choroid developed. Subsequent treatment in most cases failed to produce permanent obliteration of the new-vessels networks.
