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。

简介：目的分析初发翼状胬肉术后患者应用于退翳明目汤治疗后的疗效。方法采用随机数字表法将我院例初103发翼状胬肉术后患者分组,对照组51例应用典必殊滴眼液治疗,观察组52例给予退翳明目汤治疗,对比两组患者治疗后临床疗效、泪膜稳定性及术后复发率。结果观察组水肿消退、角膜创面上皮修复时间及干眼症状计分均低于对照组,SchirmerBUT水平均高于对照组,复发率0%低于对照组13.89P〈0.05）-Ⅰ及%（。结论退翳明目汤能够有效提升初发翼状胬肉术后患者泪液分泌量,提升泪膜稳定性,消除干眼症状,促进创面上皮修复,降低复发率。
