Objective To evaluate the clinial effect of intravitreal injection of ranibizumab combined with membrane sac injection of triamcinolone acetonide (TA) in the treatment of retinal vein occlusion (RVO) complicated with macular edema (ME). Methods There were 30 patients (30 eyes) who were diagnosed as RVO with macular edema by fundus fluorescence angiography (FFA) and optical coherence tomography (OCT). The changes of best corrected visual acuity (BCVA) and OCT were compared before and after the treatment by intravitreal injection of ranibizumab combined with membrane sac injection of TA. Results The BCVA before injection and after 1 week, 1 month, and 3 months of injection were (0.727±0.115), (0.591±0.062), (0.528±0.083), and (0.494±0.082). Central macular thickness (CMT) were (482.6±75.9) μm, (402.7±77.2)μm, (344.6±72.7)μm, and (310.6±68.7)μm respectively. BCVA was remarkably increased and CMT decreased after 1 month, 3 months, and 1 week of treatment, and the difference with those before treatment had statistical significance (P0.05). Conclusion The treatment by intravitreal injection of ranibizumab combined with membrane sac injection of TA can reduce macular edema in short time and increase BCVA. It provides a new idea for treating RVO complicated with macular edema, however, its long-term effect requires further observation.%目的：评价玻璃体腔注射雷珠单抗(ranibizumab)联合筋膜囊下注射曲安奈德(TA)治疗视网膜静脉阻塞(RVO)继发黄斑水肿(ME)的临床疗效。方法经眼底荧光血管造影(FFA)及光学相干断层扫描(OCT)检查确诊为RVO合并黄斑水肿的患者30例,30眼。对比分析单次玻璃体腔注射雷珠单抗联合筋膜囊下注射TA治疗前后最佳矫正视力(BCVA)、OCT的变化。结果治疗前与治疗后1周、1、3个月BCVA分别为(0.727±0.115)、(0.591±0.062)、(0.528±0.083)、(0.494±0.082)；黄斑中心厚度(CMT)分别为(482.6±75.9)μm、(402.7±77.2)μm、(344.6±72.7)μm、(310.6±68.7)μm。治疗后1周、1、3个月BCVA显著提高, CMT显著降低,与治疗前相比差异均具有统计学意义(P0.05)。结论玻璃体腔注射雷珠单抗联合筋膜囊下注射TA可以在短期内减轻黄斑水肿、提高BCVA,为RVO继发黄斑水肿治疗提供了新的思路,但长期效果有待进一步观察。
