目的 :探讨不打开结膜囊的小切口小梁切除术治疗原发性青光眼的效果。方法 :对 46例 (6 4眼 )行上述手术的原发性青光眼患者的眼压、视力、滤过泡及手术并发症进行回顾性总结。结果 :追踪观察末期 (平均 16个月 ) ,43例 (93.47% )患者的眼压控制在正常范围 ,平均眼压为 17.30 mm Hg (2 .31k Pa)。没有发生明显的手术并发症。结论 :小切口小梁切除术操作简便、手术并发症少 ,中期疗效优于经典的小梁切除术 Objective: To investigate the effect of small incision trabeculectomy without conjunctival sac in the treatment of primary glaucoma. Methods: The intraocular pressure, visual acuity, filtration bleb and operative complications of 46 patients (64 eyes) with primary glaucoma undergoing the operation were reviewed retrospectively. Results: In the end of follow-up observation (mean 16 months), the IOP in 43 patients (93.47%) was within the normal range and the mean IOP was 17.30 mm Hg (2.31k Pa). No obvious surgical complications occurred. Conclusion: Small incision trabeculectomy is simple, less operative complications, the mid-term efficacy is superior to the classic trabeculectomy
