Abstract:
The aim of this study was to evaluate the histopathologic changes of the pigmented rabbit ratina after endocryopexy. We investigated the differences or similarity among endocryopexy, transscleral cryopexy and laser phocoagulation. Their ultrastructural changes were observed with light and electron microscope. The results were as follows; 1. The first day after endocryopexy, we observed rupture of the internal limiting membrane, breakdown the inner and outer retina, separation of intercellular gap junction of pigment epithelial cells, and accumulation of exudation within subretinal space. 2. In the 8th days, there are mull iplication of retinal pigment epithelial cell layer and development of basal infolding. 3. The present study suggested that effects of endocryopexy on the retina to cause chorioretinal adhesion was similar to transscleral cryopexy or laser photocoagulation However it should be operated on the premise that in requires technical skill for the purpose of clinical application.
