目的：采取两种不同观察方式下手术治疗简单孔源性视网膜脱离，术后观察原裂孔与垫压嵴的关系。 方法：将35例35眼简单孔源性视网膜脱离患者随机分成两组，A组17例17眼，在外路显微手术下完成巩膜外垫压的操作过程；B组18例18眼，在间接检眼镜下完成巩膜外垫压的操作过程；A，B两组术后患者点典必殊1wk，全身应用抗生素和皮质类固醇1wk，术后随访1wk～6mo。 结果：A组原裂孔位于嵴前坡患者15眼，成功率为88%,B组位于嵴前坡者15眼，成功率为83%,两组比较无差异（P＞0.05）。 结论：两种不同观察方式下手术治疗简单孔源性视网膜脱离患者，术后观察原裂孔位于嵴前坡的病例无显著性差异。

AIM:To observe the relationship between original hole and scleral buckling after surgery therapy for simple rhegmatogenous retinal detachment by two different observation modes. METHODS: Thirty-five eyes of 35 patients with simple retinal detachment were divided into two groups.Group A including 17 patients (17 eyes) were treated by external microsurgery to complete scleral buckling operation.Group B including 18 patients (18 eyes) were treated by indirect ophthalmoscope.The patients of both groups were treated with tobradex eyedrops and systemic antibiotic and corticosteroids for one week postoperatively.The patients were followed up for 1 week to 6 months。 RESULTS: In group A,the original hole of 15 eyes located on buckled sclera and the success rate was 88%.In group B, the original hole of 15 eyes located on buckled sclera and the success rate was 83%.There was no difference between the two groups (P>0.05). CONCLUSION: There is no significant difference in postoperative cases with original hole located on buckled sclera between patients after surgery therapy for simple rhegmatogenous retinal detachment by two different observation modes
