We performed argon-laser peripheral iridotomies on the right eyes of eight cynomolgus monkeys and administered panretinal scatter photo-coagulation to the left eyes of the same monkeys. Both eyes of each monkey were photographed and studied with a slit lamp, pachymetry, and direct and indirect specular microscopy. After follow-up periods of 0 to 31 days, the monkeys were killed and the enucleated eyes studied by light and scanning electron microscopy. Scanning electron microscopy showed that the changes observed by specular microscopy were deposits on the endothelium. Only minimal damage occurred and there were no significant changes in endothelial cell density after either treatment.
