Use of digitized fluorescein angiogram system to evaluate laser treatment for subretinal neovascularization: technique.

Abstract

In patients with subretinal neovascular membranes (SRNVM), persistence of the SRNVM after laser treatment is a major cause of decreased visual acuity. Persistence is associated with inadequate initial laser treatment. A technique using a digitized fluorescein angiogram (DFA) system is presented that allows immediate evaluation of the adequacy of laser treatment for SRNVM. This involves overlaying a red-free photograph taken after treatment on a fluorescein angiogram taken before treatment using a digital angiogram system that evaluates the adequacy of treatment. A protocol for augmentation of laser treatment has been developed that will aid in the reduction of persistence after laser treatment of SRNVM.
