23 G微创玻璃体切割手术治疗视网膜静脉阻塞性玻璃体积血的有效性及安全性分析

The Efficacy and Safety Analysis of 23 G Transconjunctival Sutureless Vitrectomy in Treatment of Vitreous Hemorrhage Secondary to Retinal Vein Occlusion

目的:分析23G微创玻璃体切割手术治疗视网膜静脉阻塞性玻璃体积血的有效性及安全性。方法:将96例视网膜静脉阻塞性玻璃体积血患者按照随机数字表法分为试验组和对照组各48例,其中试验组采用23G微创玻璃体切割术,对照组采用常规玻璃体切割术。两组患者术后采用相同治疗方法及护理方法,比较两组术后视力恢复情况、眼压情况以及术中、术后并发症的发生情况。结果:两组术后视力恢复及眼压情况的比较差异均无统计学意义(P>0.05)。两组术中大量出血、医源性裂孔的发生率比较差异均无统计学意义(P>0.05),但反复更换显微器械的发生率4.17%明显低于对照组的33.33%,差异有统计学意义(P<0.05)。结论:23G微创玻璃体切割手术治疗视网膜静脉阻塞性玻璃体积血具有与传统手术相同的临床效果,可以恢复患者视力,平稳眼压,但具有较少的术中及术后并发症发生。

Objective：To analyze the efficacy and safety of 23G transconjunctival sutureless vitrectomy in treatment of vitreous hemorrhage secondary to retinal vein occlusion.Method：96 patients with vitreous hemorrhage secondary to retinal vein occlusion were divided into the experimental group and the control group according to the random number table method,48 cases in each group.The experimental group was treated by 23G transconjunctival sutureless vitrectomy,the control group was treated by conventional vitrectomy,and after the surgery,the two group patients were adopted the same treatment and nurse measurements.The visual acuity recovery status,intraocular pressure, intraoperative and postoperative complications between the two groups were compared.Result：There were no significant differences between the two groups in visual acuity recovery and intraocular pressure value（P〉0.05）.There were no significant differences between the two groups in the incidence of intraoperative massive hemorrhage and iatrogenic retinal hole（P〉0.05）,but the incidence of repeated replacement micro instruments in the experimental group was 4.17%, it was significantly lower than 33.33% in the control group,the difference was statistically significant（P〈0.05）. Conclusion：23G transconjunctival sutureless vitrectomy has the same efficacy with conventional vitrectomy,it can recover the patients’visual acuity and normalize intraocular pressure,but compared to conventional vitrectomy,the complications probability of 23G transconjunctival sutureless vitrectomy is smaller.
