[Histologic studies on the effect of light coagulation of the retina on the vitreous body].

Up to 6 months after panretinal photocoagulation of rabbit eyes the subsequent changes in the vitreous body were examined histologically by means of a stereomicroscope. Marked changes were evident: severe exudation into all of the vitreous tissue during the early follow-up period, circumscribed areas of higher density or loss of normal density, membrane-like structures, confluent cavities and liquefaction of most of the tissue at the later postcoagulative stage.
