目的:了解小梁切除术后泪膜功能的变化并分析其原因。方法:于术前,术后7、14、30、90 d对患者行BUT、STI、FL、干眼仪检查及干眼症状评分,了解术前、术后的差异。结果:术后7、14、30 d干眼症状评分、FL积分较术前增加,干眼仪正常比率、BUT、STI较术前降低,术后90 d恢复到术前水平。结论:小梁切除术会影响泪液的分泌和分布,降低泪膜的稳定性。
Objective: To understand the changes of tear film function after trabeculectomy and to analyze its causes. Methods: The patients underwent BUT, STI, FL, dry eye examination and dry eye symptom scores at preoperative, postoperative 7, 14, 30, and 90 days after operation. The preoperative and postoperative differences were observed. Results: On the 7th, the thirtieth, the 30th and the 30th postoperative day, the symptom score of dry eye and FL score increased compared with that before operation. The normal rate of dry eye, BUT and STI decreased compared with that before operation, and returned to preoperative level 90 days after operation. Conclusion: Trabeculectomy can affect the secretion and distribution of tear fluid and reduce the stability of tear film.
