Change of Microaneurysm in Diabetic Retinopathy Patients Who Undergo Bevacizumab Injection

Purpose: To evaluation of microvasular change(microaneurysm) in diabetic retinopathy patients who undergo intravitreal bevacizumab injection by FAG(fluorescein angiography). Method: Thirty- one eyes of 31 diabetic retinopathy patients undergoing intravitreal bevacizumab injection(1.25mg/0.05ml) only one eye were included in this study. The control group(31 eyes) were the opposite eyes. We made an exception for both intravitreal bevacizumab...

Reduction of Venous Filling Time Between Pre and Post PRP Correlated to the Progression of Retinal Neovascularization

Yun-Sik Yang, Yong-Woo Kim, Seong-Soo Jang, Jeong-Woon Jang Purpose: We evaluated the reduction in the venous filling time between pre and post PRP and its effect on the progression of retinal new vessel growth. Methods: We compared a “stabilized group” of 20 eyes with regressed or reduced new vessels and 12 eyes of an “unstable group” which need additional scatter photocoagulation or which had vitreous hemorrhage or needed vitreous...
