Focal laser photocoagulation can be performed directly on microaneurysms and on the microvascular lesions in the center of the rings of hard exudates, at least 500 microns from the fovea, or may be performed in the area of retinal edema without treating specific retinal vascular lesions. The mechanism of edema reduction after laser treatment is unknown, but many studies with minor technique variations suggest that it is most probably dependent on creating a grid pattern of light burns of the retinal pigment epithelium, which underlies the retin... 查看完整內容 |
