Abstract
- Adult albino rabbits were used in this study. The retina was treated with laser photocoagulation around the retinal break. The histopathologic findings were evaluated with light and electron microscopes to determine how quickly chorioretinal adhesion was produced after photocoagulation. Adhesion between the rod and cone layer and the pigment epithelium appeared within 1 hour after photocoagulation, probably due to direct burn effect of the laser. A scar tissue appeared in the chorioretinal lesion 5 days after photocoagulation, derived from the proteinaceous coagulum and accompanying fibrosis.
