title: Two-month follow-up of the changes in vitreal constituents after argon laser coagulation of the retina in rabbits.
abstract: The response of the vitreous after panretinal argon laser photocoagulation was followed over a period of 60 days. Two phases can be discerned. An an immediate reaction to the disturbance of the blood-retinal barrier at the site of the pigment epithelium the total protein content and malate dehydrogenase activity rise sharply within 3 days, 4- to 5-fold above a normal. The more protracted increase of lysosomal enzyme activities which reach their peak heigh after 14 days only, can be attributed to the action and proliferation of phagocytic cells. 2 months after treatment all parameters have returned to their normal levels.
