目的 探讨原发性视网膜脱离术前找不到裂孔的原因及处理方法。方法 回顾分析 1998年 7月～2 0 0 0年 1月我院收治的原发性视网膜脱离患者中 ,术前未找到明确裂孔的原因、处理及随访结果。结果 6 7只眼中 ,2 2只眼经努力术中查到裂孔 ,其中 2 1例视网膜完全复位 ,其手术解剖复位率为 95 .6 5 % ;6 7只眼术前术后视力比较有显著差异 (x2 =2 6 .0 9,P <0 .0 0 1) ,0 .12或以上者达 2 2只眼 (占 32 .84% ) ,手术解剖复位率达 88.0 6 % ;随访 3～ 9月 ,平均 6 .3月 ,5 7只眼视网膜完全复位 (占 85 .0 7% ) ,9只眼次全复位 ,1只眼失败 ,视力除未成功者外 ,其余均有所提高 ,与术前视力比较有显著差异 (x2 =2 0 .79,P <0 .0 0 1) ,达 0 .12以上者 2 5只眼 (占 37.31% ) ,0 .4以上者 5只眼。结论 术前详查裂孔 ,全面分析找不到裂孔的原因及术中进一步寻找裂孔是治疗此类患者的首要前提 ,掌握正确的手术方式则是成功的另一关键
Objective To investigate the reason and treatment method of preoperative retinal detachment. Methods Retrospective analysis of the patients with primary retinal detachment who were admitted to our hospital from July 1998 to January 2000, the reason, treatment and follow-up results were not found clear preoperatively. RESULTS: Twenty-seven eyes were found in 22 eyes. Among them, 21 cases of retina were completely repositioned, and 95.65% of them had anatomical reduction rate. Sixty-seven eyes had significant difference in visual acuity The difference was significant (x2 = 26.09, P <0.001), with 0.12 or more in 22 eyes (32.84%), and the anatomic reduction rate was 88.0 6% In September, an average of 6.3 months, 57 eyes completely retreated (85.07%), 9 eyes were fully subsided, 1 eye failed, the vision was not successful, the rest were improved, There were significant differences compared with preoperative visual acuity (x2 = 20.79, P <0.001), 25 eyes (more than 0.12) accounted for 37.31%, and more than 0.4 had 5 eyes. Conclusions The preoperative examination of the foramina and comprehensive analysis of the reasons that the fissure fissure can not be found and the further finding of the fissures in the operation are the most important preconditions for the treatment of such patients. It is another key to success to master the correct surgical method
