目的 :探讨非穿透小梁切除羊膜植入术治疗开角型青光眼的机理及疗效评价。方法 :对 2 0例 32眼开角型青光眼患者行非穿透小梁切除羊膜植入术 ,术后观察视力 ,眼压、滤过泡及眼内反应。随访 1～ 8个月 ,平均 6 2个月。结果 :眼压 :术前 32眼平均眼压 48 6mmHg ,术后除 1例 1眼眼压高达 2 5mmHg外 ,19例 31眼均控制在 7～ 2 0mmHg之内 ,手术成功率达 96 9%。术后视力均有显著提高 ,滤过泡扁平弥漫 ,轻微充血 ,无新生血管及纤维增殖发生。结论 :羊膜取材简便 ,疗效显著 ,为非穿透小梁手术提供了有效安全植入材料。可考虑广泛用于开角型青光眼的治疗
Objective: To investigate the mechanism and efficacy of non-penetrating trabeculectomy for amniotic membrane in the treatment of open-angle glaucoma. Methods: Non-penetrating trabeculectomy was performed in 20 patients with open-angle glaucoma of 32 eyes. Visual acuity, intraocular pressure, filtration bleb and intraocular reaction were observed after operation. Follow-up 1 ~ 8 months, an average of 6 2 months. Results: The intraocular pressure (IOP) was 48 6mmHg in 32 eyes before operation. Except for 1 case in 1 case, intraocular pressure was as high as 2 5mmHg, 19 cases (31 eyes) were all controlled within 7 ~ 20mmHg, the success rate was 96.9% . Postoperative visual acuity was significantly improved, the perforation flattened diffuse, slightly hyperemia, no new blood vessels and fiber proliferation occurred. Conclusion: The amniotic membrane is easy to draw and has good curative effect. It provides an effective and safe material for non-penetrating trabecular surgery. Can be considered widely used for the treatment of open angle glaucoma
