Efficacy of ranibizumab combined with retinal photocoagulation in patients with diabetic retinopathy
Objective: To investigate the efficacy of ranibizumab combined with retinal photocoagulation in patients with diabetic retinopathy (DR). Methods: Eighty patients (100 eyes) with DR were divided into a control group (35 patients, 40 eyes, treated with retinal photocoagulation) and an observation group (45 patients, 60 eyes, treated with retinal photocoagulation combined with vitreous cavity injection of ranibizumab) according to their different treatment method, and the treatment effects, symptom improvement and retinal thickness in the macula, best corrected visual acuity (logMAR BCVA), vascular endothelial growth factor (VEGF) levels and complications were compared between the two groups. Results: The total effective rate of the treatment was higher in the observation group than the control group (93.33% vs 77.50%, P<0.05). The time for the absorption of fundus hemorrhage, exudation and retinal edema were shorter and the macular retinal thickness, logMAR BCVA and VEGF levels were lower in the observation group than the control group (all P<0.05). There were no statistical differences in the incidence of complications between the two groups (P>0.05). Conclusion: Ranibizumab combined with retinal photocoagulation for DR patients can effectively improve clinical symptoms, protect visual function and reduce complications.

糖尿病视网膜病变(DR)是糖尿病患者最重要的微血管病变,也是当今人群主要致盲眼病之一,其引起的眼部典型病理改变为视网膜缺血刺激分泌的血管内皮生长因子(VEGF)介导的新生血管生成,因此抗VEGF药物已逐渐成为治疗DR及其引发的一系列病变,如糖尿病性黄斑水肿等的主流方式之一。近年来发现抗VEGF药物对DR患者的眼部血管及血流具有一定影响,但具体机制尚未完全阐明,本文总结了玻璃体腔内注射抗VEGF药物对DR患者眼部血管及血流影响方面的研究进展。
