目的探讨结膜松弛症术后的泪液学变化。方法对29例(32眼)结膜松弛症新月形球结膜切除,分别于术前和术后3个月进行症状评估、裂隙灯显微镜检查、泪河观察、SchirmerⅠ试验、泪膜破裂时间(BUT)、眼表荧光素染色、以及泪液清除率(TCR)对比分析。结果症状改善者29眼(90.63%),泪河高度恢复正常28眼(87.50%),SchirmerⅠ试验手术前后差异无统计学意义(P>0.05),BUT和眼表荧光素染色评分术后较术前差异有统计学意义(P<0.05),荧光素清除试验恢复正常31眼(96.88%)。结论手术切除松弛多余结膜组织可以明显改善结膜松弛症的干眼症状以及泪液动力学改变。
Objective To investigate the changes of lacrimal fluid after conjunctivochalasis. Methods 29 patients (32 eyes) with conjunctivochalasis were treated with crescentic conjunctiva resection. The symptoms were evaluated preoperatively and 3 months after surgery. Slit lamp microscopy, tear river observation, Schirmer I test, tear film breakup time (BUT ), Ocular surface fluorescein staining, and tear clearance (TCR). Results There were 29 eyes (90.63%) with symptom improvement and 28 eyes (87.50%) with normal height of tear river. There was no significant difference in Schirmer Ⅰ test before and after operation (P> 0.05). BUT and ocular surface fluorescein staining score The difference was statistically significant (P <0.05), and the fluorescein clearance test returned to normal in 31 eyes (96.88%). Conclusion Surgical removal of excess conjunctival tissue can significantly improve the symptoms of conjunctivochalasis dry eye and tear dynamic changes.
