目的 探讨巩膜遂道成形术治疗青光眼的效果。方法 对 5 1例 70眼的各类型青光眼施行巩膜遂道成形术 ,并且根据术中内层巩膜瓣下暴露的小梁及角膜内皮表面房水溢出的情况选择进入前房或不进入前房两种方式。结果 随访 6～ 30个月 ,不用药物治疗 ,眼压控制在 2 0 m m Hg以下者 6 8眼 ,手术成功率为 97.1% ,仅 2眼眼压失控的病例 ,1眼是新生血管性青光眼 ,1眼是开角性近绝对期青光眼 ,分别经二极管激光术和再次巩膜遂道成形术治疗 ,眼压控制在 8～ 10 mm Hg之间。结论 应用巩膜遂道成形术治疗青光眼 ,可明显提高成功率 ,根据术中情况选择方法 ,减少眼部组织损伤 ,从而减少和避免术中及术后并发症 ,并适合各类型青光眼的治疗
Objective To investigate the effect of scleral tunnel surgery on glaucoma. Methods 51 cases of 70 eyes of all types of glaucoma were performed scleral tunnel angioplasty, and according to the intraoperative scleral flap exposed under the inner scleral flap and corneal endothelial surface of the aqueous humor out of the situation to choose into the anterior chamber or do not enter the anterior chamber two Kind of way. Results The patients were followed up for 6 to 30 months without treatment. The intraocular pressure was controlled at 68 eyes below 20 mm Hg, the operative success rate was 97.1%, only 2 eyes had uncontrolled intraocular pressure, 1 was neovascular glaucoma, 1 eye is open angle near absolute glaucoma, respectively, by diode laser and re-scleral tunnel surgery, intraocular pressure control in 8 ~ 10 mm Hg between. Conclusion The use of scleral tunnel approach for the treatment of glaucoma can significantly improve the success rate, according to intraoperative selection method to reduce eye tissue damage, thereby reducing and avoiding intraoperative and postoperative complications, and for the treatment of various types of glaucoma
