简介：目的：观察翼状胬肉切除联合角膜缘干细胞移植及术后药物治疗翼状胬肉的临床疗效。方法：共行翼状胬肉切除联合角膜缘干细胞移植术治疗的翼状胬肉患者760例980眼。选取亚复发期的162例162眼进行观察,随机分为A,B两组,A组滴1g/L丝裂霉素C＋诺氟沙星滴眼液1～3mo;B组交替滴地塞米松滴眼液、双氯芬酸钠滴眼液1～3mo。结果：A组痊愈67眼（81.7%）,亚复发12眼（14.6%）,复发3眼（3.7%）。B组痊愈35眼（43.8%）,亚复发29眼（36.3%）,复发16眼（20.0%）。A组复发率明显低于B组（P〈0.01）。结论：翼状胬肉切除联合自体角膜缘干细胞移植术,无排斥反应、安全有效、术后复发率低,术后给予滴眼液后续治疗尤为重要,更能有效地抑制和降低翼状胬肉术后的复发率,能明显提高治疗效果。

简介：目的：探讨激光周边虹膜成形术（laserperipheraliridoplasty,LPIP）治疗急性闭角型青光眼（acuteangle-closureglaucoma,AACG）急性发作期药物不能控制的高眼压持续状态中的疗效。方法：原发性急性闭角型青光眼67例69眼发作期药物治疗3～6h后眼压仍〉30mmHg时,行LPIP治疗。监测术前和术后30,60min和2h眼压、视力变化。应用UBM测量术前、术后2h房角宽度和虹膜厚度,并应用房角镜观察前房角粘连情况。结果：LPIP后2h,房角开放距离（AOD）较术前明显增大（P〈0.01）,小梁虹膜夹角（TIA）增宽、部分患者周边虹膜前粘连（PAS）减少、周边虹膜变薄。所有患者眼压在激光虹膜成形术后不同时间均有不同程度下降。术前平均眼压53.81±10.22mmHg,术后30min平均眼压33.81±9.22mmHg,术后60min为21.93±7.19mmHg,2h后眼压下降至15.16±3.07mmHg,治疗前后差异有显著统计学意义（F=151.79,P〈0.01）。同时所有患者视力都有所提高。结论：LPIP可以明显加深患者的周边前房,增宽房角入口,降低患者眼压,是治疗AACG急性发作期药物不能控制高眼压持续状态的重要辅助措施,为青光眼的进一步治疗创造了条件,并且能够改善预后。
