简介：目的：观察小牛血去蛋白提取物眼用凝胶对复发性翼状胬肉术后角膜切口修复的应用疗效。方法：将68例68眼行复发性翼状胬肉术后发生角膜切口水肿的患者随机分为2组,每组34例。对照组常规应用双氯芬酸钠滴眼液加抗生素滴眼液同时加用贝复舒滴眼液交替点眼,4次/d。治疗组除每日应用双氯芬酸钠滴眼液加抗生素滴眼液交替点眼外,使用小牛血去蛋白提取物眼用凝胶,4次/d,疗程1mo,于用药前和用药后3,7,14d;1mo分别对患者主觉症状、体征、角膜切口修复情况进行对比分析。结果：复发性翼状胬肉术后3,7,14d,治疗组角膜切口水肿较对照组明显消退,切口修复较快,主觉症状在短时间消退,术后1mo,两组无显著性差异。结论：小牛血去蛋白提取物眼用凝胶对复发性翼状胬肉术后角膜切口的早期修复起效时间短、舒适度好、安全性良好,对减少术后感染性角膜病的发生及术后角膜散光有良好的作用。

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。

简介：目的探讨前列腺素类药结合玻璃体腔注射雷珠单抗治疗新生血管性青光眼的效果。方法伴发高眼压的新生血管性青光眼患者160例根据随机数字表法分为治疗组80例与对照组80例,两组都给予复合式小梁切除术,对照组选择拉坦前列腺素辅助治疗,治疗组选择拉坦前列腺素联合玻璃体腔注射雷珠单抗辅助治疗。结果治疗后治疗组与对照组的治疗有效率分别为97.5%和88.8%,治疗组的治疗有效率明显高于对照组（P〈0.05）。两组治疗后最佳矫正视力都明显提高,而眼压都明显下降,与治疗前对比差异明显（P〈0.05）;同时治疗后治疗组的最佳矫正视力与眼压也都明显好于对照组（P〈0.05）。治疗期间治疗组的眼结膜充血、前房炎症反应、角膜水肿、一过性视觉模糊等并发症发生率都明显低于对照组（P〈0.05）。所有患者治疗后随访调查6个月,治疗组的治疗后3个月与6个月的复发率分别为1.3%和5.0%,而对照组分别为7.5%和13.8%,治疗组治疗后3个月与6个月的复发率明显少于对照组（P〈0.05）。结论前列腺素类药结合玻璃体腔注射雷珠单抗治疗新生血管性青光眼能促进眼压的降低,改善视力水平,安全性好,降低复发,从而有利于近远期疗效的提高。
