目的:研究改良型非穿透性小梁切除术治疗原发性青光眼的临床效果。方法:原发性青光眼21例30眼施行改良型非穿透性小梁切除术,切除小梁网和Schlemm管外壁组织1.0mm×3.0mm,保留最内层组织,于术后1wk;1,6mo;1a及5a以上(最长10a)观察临床效果。结果:早期随访不用抗青光眼药物眼压低于2.7kPa者28眼,有效率达93%,长期随访眼压低于2.7kPa者27眼,有效率达90%。术后无严重并发症发生。结论:改良型非穿透性小梁切除术在早期和平均5a随访中能有效降低原发性开角型和闭角型青光眼患者眼压,因不穿透前房而术后并发症少,是一种理想的原发性青光眼手术方法。
Objective: To study the clinical effect of modified non-penetrating trabeculotomy in the treatment of primary glaucoma. METHODS: Thirty eyes of 21 eyes with primary glaucoma underwent modified non-penetrating trabeculotomy. The outer wall of the trabecular meshwork and Schlemm’s canal was excised to 1.0 mm × 3.0 mm. The innermost layer of the tissue was preserved at 1 week after operation. 6mo; 1a and 5a above (up to 10a) to observe the clinical effect. Results: In the early follow-up, there were 28 eyes with intraocular pressure less than 2.7kPa in anti-glaucoma medication, the effective rate was 93%. The long-term follow-up was 27 eyes with intraocular pressure less than 2.7kPa, the effective rate was 90%. No serious postoperative complications occurred. CONCLUSIONS: Modified non-penetrating trabeculotomy can effectively reduce the intraocular pressure in patients with primary open-angle and angle-closure glaucoma at an early stage and mean follow-up of 5a. Because it does not penetrate the anterior chamber and has fewer postoperative complications, Is an ideal primary glaucoma surgery methods.
