摘要:

目的 探讨局部使用前列腺素滴眼剂对角膜厚度及眼压的影响。设计 前瞻性比较性病例系列。研究对象 119例原发性开角型青光眼患者。方法 随机分0.004%曲伏前列素滴眼剂组(Tra组)(71眼)和0.15%酒石酸溴莫尼定滴眼剂组(Bri组)(48眼)。利用Pentacam 眼前段分析仪检查用药3、6个月后两组患者的中央角膜厚度(CCT)、顶端角膜厚度(ApexCT)、最薄角膜厚度(TCT)以及距离TCT 2、4、6、8 μm处的角膜厚度(CT2、CT4、CT6、CT8)变化,以及Goldmann压平眼压计校正眼压(c-IOP)值的变化。主要指标 中央和周边角膜厚度、矫正眼压。结果 用药前及用药6个月后Tra组CCT变化在(555.35±36.51)~(549.68±36.43) μm(P均<0.05)、ApexCT变化在(553.80±36.42)~(549.14±36.41) μm(P均<0.05)、TCT变化在(552.11±36.29)~(546.15±35.87) μm(P均<0.05)以及CT2、CT4、CT6、CT8较用药前均有相似变薄趋势(P均<0.05)。其中用药3个月CCT较用药前平均变薄(4.63±0.62) μm,6个月时平均变薄(5.67±0.64)μm。用药前与用药3、6个月的c-IOP差异均无统计学意义。Bri组用药3、6个月后角膜厚度及c-IOP差异均无统计学意义(P均>0.05)。结论 局部使用前列腺素滴眼剂是导致角膜厚度变薄的潜在危险因素,而眼压矫正值无明显影响。(眼科,2016,25: 18-22)

Abstract:

Objective To observe the effect of topical using of prostaglandin eye drops on the thickness of the cornea and intraocular pressure. Design Prospective comparable case-control study. Participants One hundred nineteen patients with primary open angle glaucoma. Methods Patients were randomly divided into two groups, 71 eyes in 0.004% travoprost eye drops group (Tra group) and 48 eyes in 0.15% brimonidine tartrate eye drops group (Bri group). Central corneal thickness(CCT), apex corneal thickness (Apex CT), thinnest corneal thickness(TCT) and every 2 μm distant from TCT point were assessed by Pentacam Analyzer and intraocular pressure (IOP) by Goldmann applanation tonometer was corrected at the 3 and 6 months follow up.  Main Outcome Measures Central and peripheral corneal thickness; corrected intraocular pressure. Results At the last follow up, the CCT from 555.35±36.51 μm to 549.68±36.43 μm (P<0.05), Apex CT from 553.80±36.42 μm to 549.14±36.41 μm (P<0.05), TCT from 552.11±36.29 μm to 546.15±35.87 μm (P<0.05) and similar to corneal thickness from TCT 2 μm, 4 μm and 6 μm, 8 μm (CT2 and CT4, CT6 and CT8) in Tra group (P<0.05). In the 3 months, CCT was getting thinner for average 4.63±0.62 μm after 3 months’ treatment and average 5.67±0.64 μm after 6 months’ treatment. There were no significant differences in corrected intraocular pressure(c-IOP) at the baseline and the follow up (P>0.05). And no significant statistical differences was found between corneal thickness and c-IOP in Bri-group (P>0.05).  Conclusion Topical use of prostaglandin eye drops is one of potential risk factors to make corneal thinner, despite of no effect on c-IOP.  (Ophthalmol CHN, 2016, 25: 18-22)
