简介:目的:观察翼状胬肉切除联合自体球结膜瓣移植术后,局部应用1g/L环孢霉素A对胬肉复发的抑制效果。方法:对原发性翼状胬肉患者58例58眼进行前瞻性研究。所有入选眼均采用翼状胬肉切除联合自体球结膜瓣移植术,根据术后是否应用1g/L环孢霉素A滴眼液分为试验组和对照组。术后追踪随访1a,观察患者的胬肉复发率。结果:术后试验组基础泪液分泌试验(SchirmerⅠtest,SⅠt)结果明显优于对照组(9.93±1.59vs8.47±1.53mm/5min);SⅠt结果也显示1g/L环孢霉素A使患眼术后的泪液分泌量较术前有所增加。术后1a试验组与对照组的胬肉复发率分别为10%和39%。对照组并发症的出现率要高于试验组,差异具有统计学意义(P=0.029)。结论:翼状胬肉切除术后局部应用1g/L环孢霉素A滴眼液能够安全有效地降低胬肉的复发率。
简介:目的评价庆大霉素双氯芬酸钠控制白内障和青光眼术后炎症反应的疗效和安全性。方法采用临床多中心、随机、双盲、对照试验。试验组和对照组分别滴用庆大霉素双氯芬酸钠和复美新,每日4次,观察2wk。结果内眼术后试验组和对照组中有效率分别是71.43%和65.52%,两者间的差异无统计学意义。两组的不良事件发生率也无统计学意义。结论庆大霉素双氯芬酸钠是控制内眼术后(白内障手术和青光眼手术)有效和安全的药物。(中国眼耳鼻喉科杂志,2006,6:223~225)
简介:目的观察七叶洋地黄双苷滴眼液(施图伦)对青少年低度数近视及视疲劳症状的治疗效果。方法收集于2015年6月至9月就诊于浙江省台州医院眼科门诊的青少年近视患者120例240眼,根据用药情况不同随机分为对照组,托吡卡胺组,施图伦组,每组40例80眼,分别比较三组用药前与用药后一月的裸眼视力与屈光状态,根据视疲劳问卷调查表评估用药前后的视疲劳症状变化。结果(1)裸眼视力:施图伦组及托吡卡胺组较治疗前裸眼视力均有一定程度提高,差异有统计学意义(P〈0.05)。(2)近视度数:施图伦组较治疗前矫正度数下降,差异有统计学意义(P〈0.05),托吡卡胺组矫正度数较治疗前有下降,差异有统计学意义(P〈0.05)。对照组矫正度数较治疗前对比无差异。(3)视疲劳症状:施图伦组视疲劳症状改善37例,总改善率达92.5%。对照组及托吡卡胺组对比治疗前差异无统计学意义。结论施图伦滴眼液能显著改善近视患者的视疲劳症状,对于低度数近视有一定的治疗作用。
