摘要: 目的 观察雷珠单抗联合地塞米松玻璃体内植入剂治疗视网膜分支静脉阻塞继发黄斑水肿(macular edema secondary to branch retinal vein occlusion, BRVO-ME)的效果。方法 纳入2020年1月至2022年5月保定市第一中心医院眼科确诊为BRVO-ME且临床资料完整的患者67例67只眼,按照治疗方法的不同将患者分为单药组及联合组,其中单药组37例37只眼,联合组30例30只眼。所有患者行玻璃体腔注射雷珠单抗注射液0.05 mL治疗,联合组于雷珠单抗治疗1周后行地塞米松玻璃体内植入剂0.7 mg玻璃体腔注射;分别于治疗前和治疗后4周检测最佳矫正视力(best corrected visual acuity, BCVA),应用相干光断层扫描成像(optical coherence tomography, OCT)分析黄斑中心凹厚度(central macular thickness, CMT)变化,相干光断层扫描血管成像(optical coherence tomography angiography, OCTA)分析黄斑区浅层视网膜血管灌注密度(vessel perfusion density, VPD)及血管长度密度(vessel length density,VLD)变化。依据患者复诊的情况判断是否需要再次治疗,如果随访复查时OCT的黄斑区域出现视网膜内液或视网膜下液,CMT≥300 μm或BCVA持续下降,需再次接受雷珠单抗注射者则终止观察。结果 初诊时联合组和单药组BCVA、CMT比较差异无统计学意义(P>0.05),治疗后2组BCVA、CMT较治疗前均降低(P<0.05)且治疗后联合组BCVA、CMT低于单药组(P<0.05)。而2组患者治疗前后黄斑区浅层毛细血管中心、内环、外环及完整的VLD及VPD均无明显变化(P>0.05)。2组治疗前后结果进行组间比较,VLD、VPD结果均无统计学意义(P>0.05)。结论 玻璃体腔内注射雷珠单抗联合地塞米松玻璃体内植入剂治疗BRVO-ME可降低黄斑水肿,改善视力及黄斑区结构和功能,并且疗效可持续。但二者早期疗效相似,协同作用不明显。

Abstract: Objective To observe the effcts of intravitreal of ranibizumab and DEX implant in macular edema secondary to branch retinal vein occlusion(BRVO-ME). Methods 67 cases with BRVO-ME in the Department of Ophthalmology of Baoding No.1 Central Hospital were included from January 2020 to May 2022. According to the different methods of treatment,all patients were divided into ranibizumab group and combined treatment group, 37 cases of 37 eyes in the ranibizumab group and 30 cases of 30 eyes in the combined treatment group. All patients were treated with intravitreal injection of ranibizumab,and the combined treatment group was treated with ranibizumab and 1 week later with 0.7 mg DEX implant. The best corrected visual acuity(BCVA), the central macular thickness(CMT)and the vessel perfusion density(VPD), vessel length density(VLD)were evaluated detected with optical coherence tomography(OCT and OCTA)before and after treatment. Depending on the patient's follow-up, the following situation occurs would stop observing. If intra-retinal/sub-retinal accumulation fluid appeared in the macular area, the BCVA continued to decline, or the CMT≥300 μm, with the increase in CMT. Results There was no significant difference in BCVA and CMT between the combination group and the single drug group at the first diagnosis(P>0.05). After treatment, the BCVA and CMT of the two groups were lower than those before treatment(P<0.05), and the BCVA and CMT of the combination group were lower than those of the single drug group after treatment(P<0.05).While no significant difference was found in VPD and VLD at the central, inner, otuer, full region in the superficial retinal capillary plexus within 6 mm×6 mm of macular area before and after treatment(P>0.05). Conclusion In eyes with BRVO-ME, treatment with an anti-VEGF agent plus DEX implant could provide a predictable duration of effect, as well as significant improvements in BCVA and CMT. However, the early efficacy of the two is similar, and the synergistic effects are not obvious.
