Objective To give the injection of the glass body of the patients with choroidal neovascularization (CNV), and analyze the influence of the retina and visual function. Methods Group selection 67 cases of CNV in our hospital from Oc-tober 2014 to November 2015 were selected and divided into observation group (n=33) and control group (n=34) according to the different treatment method.The observation group was treated with laser electric coagulation therapy combined with intravitreal ranibizumab injection,the control group was used laser therapy combined with antibiotics and Tobramycin and Dexamethasone Ophthalmic Suspension electric coagulation.The total effective rate was compared between the two groups. Results The total effective rate of observation group was 87.87% (29/33), the control group total effective rate was 55.88%(19/34), the total effective rate of the two groups was significantly different (P< 0.05). Conclusion In vivo injection of CNV can effectively inhibit the formation of blood vessels, the effect is significant.%目的：给予脉络膜新生血管(CNV)患者雷珠单抗玻璃体内注射，并分析其对黄斑区视网膜和视功能的影响。方法整群选取该院2014年10月—2015年11月收治的CNV患者67例，依据患者所选治疗方法不同分为观察组(n=33)和对照组(n=34)，观察组采用激光电凝联合雷珠单抗玻璃体内注射治疗，对照组采用激光电凝联合抗生素和妥布霉素地塞米松滴眼液治疗，对比两组治疗总有效率。结果观察组的总有效率为87.87%(29/33)，对照组总有效率为55.88%(19/34)，两组总有效率比较差异有统计学意义(P<0.05)。结论雷珠单抗玻璃体内注射治疗CNV能有效抑制血管的生成，效果显著。
