An investigation of the effects of photothrombosis and photocoagulation on corneal neovascularization

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