Abstract
- BACKGROUND Retinal vein occlusion-induced macular edema (RVO-ME) is a significant global cause of vision loss, with the effectiveness of combined anti-vascular endothelial growth factor (anti-VEGF) drugs and dexamethasone implantation (DEX I) being a relevant, yet not thoroughly explored, area of interest.The aim of this study was to evaluate the 1-year clinical efficacy of combination therapy using anti-vascular endothelial growth factor (VEGF) drugs and dexamethasone implantation (DEX I) in the treatment of macular edema secondary to retinal vein occlusion (RVO-ME). MATERIAL AND METHODS This retrospective study analyzed data from 34 RVO-ME patients treated at the Inner Mongolia Chaoju Eye Hospital between January 2020 and December 2021. All patients underwent initial DEX I treatment, followed by the introduction of anti-VEGF drugs, and were observed for one year. Retinal structural and vascular changes were measured using spectral domain optical coherence tomography (SD-OCT) and OCT angiography (OCTA). The study also evaluated shifts in best corrected visual acuity (BCVA) throughout the observation period. RESULTS Following the combined therapy, patients showed significant improvements in BCVA, intraocular pressure (IOP), central retinal thickness (CRT), and retinal vessel density (VD) (all P<0.05). Upon stratifying the results by RVO type, patients with branch retinal vein occlusion (BRVO)-ME displayed more significant BCVA improvement and CRT reduction at various post-treatment intervals compared to those with central retinal vein occlusion (CRVO)-ME (all P<0.05). CONCLUSIONS The combined use of anti-VEGF drugs and DEX I showed promising one-year efficacy in treating RVO-ME, with greater improvements noted in patients with BRVO-ME compared to those with CRVO-ME. Despite the positive results, close monitoring of IOP elevation, a notable side effect, remains crucial.
