目的 观察硅胶泪点塞治疗获得性泪点狭窄的临床效果.方法 回顾性分析2017年4月至2019年4月共23例(46眼)获得性泪点狭窄的资料,将患者的手术眼纳入观察组(23眼),手术显微镜下行泪点扩张后置入硅胶泪点塞,2个月后拔除泪点塞.患者的非手术眼作为对照组,进行泪点扩张器扩张和泪道冲洗治疗,每周1次,连续治疗2个月.在泪点塞拔除后第1、2、3个月,分别观察两组眼的泪点形态及溢泪症状.结果 观察组23眼术后未出现泪点塞移位、脱落,泪点塞拔除术后随访第1、2、3个月的治愈率分别是100％、90.5％、80.9％,显效率100％;对照组治疗前后泪点直径变化不明显,好转率仅为21.7％.结论 硅胶泪点塞置入法治疗泪点狭窄安全、简单、有效.“,”Objective To observe the clinical efficacy of silicone punctal plug for the treatment of acquired lacrimal puncta stenosis. Methods The data of 46 eyes of 23 cases with acquired lacrimal stenosis from Apr. 2017 to Apr. 2019 were analyzed retrospectively. The observation group, 23 operative eyes, received punctum dilation followed by silicone punctal plug inserted into lacrimal punctum under surgjcal microscope and silicone punctal plug extraction after 2 months. The control group, 23 non-operative eyes, treated with lacrimal point dilator and lacrimal duct irrigation once a week for 2 months. Results No complication such as displacement or exfoliation of silicone punctual plug occurred in the observation group. The cure rate at 1,2 and 3 months after silicone punctal plug extraction were 100％, 90. 5％, 80. 9％,and the apparent improvement rate was 100％. In the control group, the diameter of puncta was unchanged after treatment, and the improvement rate was only 21. 7％. Conclusion Silicone punctal plug for the treatment of acquired lacrimal puncta stenosis is an effective and safe procedure.
