망막분지정맥폐쇄에서 황반부종 형태에 따른 유리체강내 베바시주맙 주입술 효과와 주입횟수 비교

다국어 초록 (Multilingual Abstract)

Purpose: To compare the effects of intravitreal bevacizumab injection (IVB) in 3 types of macular edema secondary to branch retinal vein occlusion (BRVO). Methods: Patients with macular edema secondary to BRVO with at least 1-year follow-up after IVB were included in the present retrospective study. The authors classified the macular edema into 3 types according to OCT findings: diffuse macular edema (type 1), cystoid macular edema (type 2), and serous retinal detachment (type 3). The clinical outcome indicators were best corrected visual acuity, central macular thickness (CMT), and total number of injections. Results: The total injection number was significantly higher in type 2 than type 3 (p = 0.02). Changes in CMT were significantly different between type 2 and type 3 (p = 0.03). CMT decreased significantly after IVB in all types of macular edema. Conclusions: Morphologic classification of macular edema with OCT is useful for predicting efficacy of IVB in macular edema secondary to BRVO. J Korean Ophthalmol Soc 2012;53(8):1112-1117
