AN INVESTIGATION OF THE EFFECTS OF PHOTOTHROMBOSIS AND PHOTOCOAGULATION ON CORNEAL NEOVASCULARIZATION

This study reports on the intracellular effects of photocoagulation an d photothrombosis applications on experimental corneal neovascularizat ion created in rabbit eyes. Some vessels were left untreated as contro ls while others were subjected to argon laser photocoagulation and pho tothrombosis. The resulting ultrastructural changes, which take place relatively moderately in photocoagulation compared with those in photo thrombosis, were responsible for the vessel blockage occurring at low energy levels in photothrombosis.
