Abstract:
PURPOSE: To evaluate microvascular change (microaneurysm) in diabetic retinopathy patients who undergo intravitreal bevacizumab injection using fluorescein angiography (FAG). METHODS: Thirty one eyes of 31 diabetic retinopathy patients undergoing intravitreal bevacizumab injection (1.25 mg/0.05 mL) in only 1 eye were included in this study. The control group (31 eyes) consisted of the fellow eyes. We excluded cased with intravitreal bevacizumab injection in both eyes and medial opacity obscuring three fundus image due to vitreous hemorrhage. The microaneurysmal change was analyzed at the same site the circle with optic disc radius and macula using FAG 2 to 4 months after injection. RESULTS: The average number of microaneurysms was 42.58 +/- 33.93 and significantly decreased to 28.74 +/- 28.06 after intravitreal bevacizumab injection (p < 0.05). The decrease of 35.70 +/- 24.79% in the treatment group was statistically higher than 13.95 +/- 38.21% in the control group with the fellow eyes (p < 0.05). CONCLUSIONS: In the present study, intravitreal bevacizumab injection reduced neovascularization, cystoid macular edema. Therefore this data can be used for future research on microvascular changes in the retina.
