ERG and VER findings after laser photocoagulation of the retina.

The present investigation analyzes the results of the ERG and VER studies after argon-laser photocoagulation of the papillomacular region and after panretinal argon-laser photocoagulation. The author stresses the possibility of photocoagulation of the papillomacular region without risk of damaging the papillomacular fibers as well as the observation that panretinal photocoagulation performed under identical parameters does not affect electric activity (and consequently the anatomical integrity of the retina) to the same extent in different eyes. The ERG could thus be used for an objective assessment of the degree of adequacy of panretinal photocoagulation.
