简介:目的探讨中、晚期新生血管性青光眼的治疗方法及疗效。方法对中、晚期新生血管性青光眼29例(30眼),根据屈光间质情况分成光凝组和冷凝组,分别行超全视网膜光凝或全视网膜冷凝治疗,再结合行巩膜池小梁切除术,术后观察两组患者的视力、眼压、虹膜新生血管消退情况及并发症等。结果术后随访6-18个月,平均(10.2±3.65)月。术后所有患者眼痛、头痛症状消失。光凝组16例,17眼,术后14眼眼压控制在21mmHg(1mmHg=0.133kPa)以下,手术成功率82.4%,3眼需加用药物控制后眼压〈25mmHg,术后视力提高8眼(47.1%),15眼虹膜新生血管消退,2眼部分消退,残存数根干瘪的新生血管,冷凝组:13眼,术后10眼眼压控制在正常范围,手术成功率为76.7%,2眼需加用药物治疗,1例出现眼球萎缩。术后视力提高3眼(23.1%),11例虹膜新生血管完全消退,2例部分消退。结论超全视网膜光凝或冷凝结合巩膜池小梁切除术是治疗中、晚期新生血管性青光眼的有效方法,适于基层医院开展。
