Selective visualization of choroidal neovascular membranes.

Abstract

This study, in an animal model of CNV, shows that laser-targeted angiography demonstrates CNV and its flow dynamics in a manner not provided by conventional fluorescein angiography. It holds clinical promise as a method to delineate CNV considered difficult or impossible to detect by fluorescein angiography. The method also may permit selective photocoagulation of feeding vessels in the choroid, thereby limiting damage to the overlying retina.
