雷珠单抗联合577nm微脉冲激光治疗重度糖尿病性黄斑水肿

Clinical effect of Ranibizumab combined with 577nm micropulse laser in the treatment of severe diabetic macular edema

目的:观察雷珠单抗联合577nm微脉冲激光治疗重度糖尿病性黄斑水肿(DME)的临床疗效。方法:选取2016-06/2019-09就诊于广西壮族自治区人民医院确诊为重度DME的患者52例52眼,随机分为观察组(26例26眼,予雷珠单抗联合577nm微脉冲激光治疗)和对照组(26例26眼,仅予雷珠单抗治疗)。两组患者均予“3+PRN”方案行玻璃体腔注射雷珠单抗治疗。治疗(首次玻璃体腔注射)后随访9mo,观察黄斑中心凹厚度(CMT)、最佳矫正视力(BCVA)情况及玻璃体腔注射雷珠单抗次数。结果:与治疗前相比,两组患者治疗后各时间点CMT、BCVA均明显改善(均P<0.001),但两组间均无差异(P>0.05)。随访期间,观察组玻璃体腔雷珠单抗注射次数明显少于对照组(5.88±1.24次vs 7.12±1.24次,P=0.001)。结论:雷珠单抗联合577nm微脉冲激光和单用雷珠单抗均能有效降低重度DME患者黄斑水肿程度,改善视力,但联合治疗可减少雷珠单抗的注射次数。

AIM:To observe the clinical effect of ranibizumab combined with 577 nm micropulse laser in the treatment of severe diabetic macular edema(DME). METHODS:There were 52 eyes of 52 patients diagnosed with severe DME who admitted to the People’s Hospital of Guangxi Zhuang Autonomous Region from June 2016 to September 2019. The patients were randomly divided into the observation group(26 patients with 26 eyes, treated with ranibizumab combined with 577 nm micropulse laser) and the control group(26 patients with 26 eyes, treated with ranibizumab alone). Patients in both groups received intravitreal injection of ranibizumab with “3+PRN” regimen. Followed up at 9 mo after treatment to observe the central macular thickness(CMT), the best corrected visual acuity(BCVA) and the times of intravitreal injection of ranibizumab in the two groups.RESULTS:Compared with before treatment, the CMT and BCVA of the two groups were significantly improved at each time point after treatment(all P<0.001), but there was no difference between the two groups(P>0.05). During the follow-up period, the times of vitreous injection of ranibizumabin the observation group was significantly less than that in the control group(5.88±1.24 times vs 7.12±1.24 times, P=0.001). CONCLUSION:Both ranibizumab combined with 577 nm micropulse laser and ranibizumab alone are effective in reducing edema and improving vision in patients with severe DME, but the combination therapy reduces the times of injection.
