玻璃体切割手术对近视牵引性黄斑病变患者的效果分析

Effect analysis of vitrectomy for patients with myopic traction maculopathy

目的:探讨近视牵引性黄斑病变(MTM)患者应用玻璃体切割手术治疗的临床疗效。方法:选取50例确诊MTM患者为研究对象,根据MTM的发展阶段将其分为早期组与后期组,均为25例(26眼),同时接受玻璃体切割手术,比较术后患者视力改善情况、黄斑形态以及视网膜复位情况。结果:早期组患者26只眼视力改善率100.0%,后期组患者视力改善率为61.5%,显著低于早期组,差异有统计学意义(P<0.05);早期组患者视网膜复位Ⅰ、Ⅱ分别为100.0%,0.0%,与后期组的92.3%、7.7%比较差异无统计学意义(P>0.05);黄斑形态分级早期组25例患者26只眼均为Ⅰ级,占100.0%,后期组Ⅰ、Ⅱ、Ⅲ分别为19.2%、57.7%、23.1%,两组比较差异有统计学意义(P<0.05)。结论:玻璃体切割手术在阻止MTM患者黄斑裂孔形成方面有疗效显著。

Objective: To study clinical effects of vitrectomy for patients with myopic traction maculopathy( MTM). Methods: 50 patients,who were diagnosed with MTM,were divided into early and late group,with 25 cases( 26 eyes) in each group. They were given vitrectomy surgery. The postoperative vision improvement,macular morphology and retinal reattachment situation of the two groups were compared. Results: The vision improvement rate of late group( 61. 5%) was significantly lower than that of early group( 100%),and the difference was statistically significant( P < 0. 05). The rates of retinal reattachment I and II of early group and late group were 100. 0%,0. 0% and 92. 3%,7. 7%,and the differences were statistically insignificant( P > 0. 05). The macular morphologies of early group were all classified level,accounting for 100. 0%,while those of late group were classified as I,II,and III,accounting for 19. 2%,57. 7% and 23. 1%,respectively,and there were statistically significant differences between the two groups( P < 0. 05). Conclusions: Vitrectomy is the effective measure to prevent macular hole for the patients with MTM.
