A Clinical study on Therapeutic Effect of the Argon Laser Photocoagulation for Prevention of Vitreous Hemorrhage in BRVO

ABSTRACT

Branch retinal vein occlusion(BRVO) is the most frequent entity of retinal vascular abnormality following diabetic retinopathy; a review of diagnosis for all our new outpatients verifies this, Sudden loss of visual acuity occur in the vast majority of BRVO patients. Other complications are macular edema, capillary nonperfusion, neovascularization, vitreous hemorrhage and so on. We did a clinical analysis of 71 patients with BRVO(71 eyes), who were considered to be treated with laser photocoagulation to prevent vitreous hemorrhage. We confirmed the fact that laser photocoagulation could prevent vitreous hemorrhage to a significant degree, but we were unable to demonstrate any statistical correlation between the occurrence of vitreous hemorrhage and the time of laser photocoagulation.
