Abstract

Background: Diabetic retinopathy is the leading cause of vision loss in diabetic patients. Bevacizumab is used to regress neovascularization in proliferative diabetic retinopathy. Objectives: Determine the successful treatment rate of Bevacizumab and some factors related to the treatment outcomes of diabetic retinopathy at Can Tho City General Hospital in 2023-2024. Materials and Methods: A non-randomized, non-controlled clinical intervention study was conducted on 60 patients with diabetic retinopathy. Patients were treated with intraocular Bevacizumab injection and monthly monitoring and evaluation for 6 months on visual acuity, ophthalmoscopy images, retinal tomography, retinal thickness, blood glucose, HbA1C, and total cholesterol. Results: The overall mean age of the 60 patients was 61.1±11.9 years old. Men constituted a larger share (56.7%) than women (43.3%). The successful treatment rate was 85%. After 6 months of treatment, the level of fair and good vision increased, accounting for 40% and 48.3%, respectively. Regarding complications, 16.7% of patients had pain and 8.3% had conjunctival hemorrhage. Some factors related to successful treatment results include: Duration of diabetes 5-10 years (p=0.03); ophthalmoscopic lesions (p=0.02); Damage via retinal tomography (p=0.001); retinal thickness <250 μm (p=0.001); Blood cholesterol (p=0.004). Conclusion: Bevacizumab achieved an 85% successful clinical outcome in treating diabetic retinopathy and can continue per treatment protocol and indication.
