白内障超声乳化术前睑板腺按摩对合并睑板腺功能障碍患者术后眼表的影响

目的：：探讨合并有睑板腺功能障碍( Meibomian gland dysfunction,MGD)的白内障患者在术前行睑板腺按摩对术后眼表的影响。方法：选取合并MGD的白内障患者90例93眼,随机分为两组,试验组在术前1 wk每天行眼睑部热敷及睑板腺按摩,对照组不采取措施。两组患者均行白内障超声乳化联合人工晶状体植入术。分别于术前、术后1 wk进行裂隙灯显微镜检查,记录并比较两组的睑缘形态评分、睑板腺分泌物评分、泪液分泌试验( Schirmer Ⅰ test,SⅠt)、泪膜破裂时间( break-up time,BUT)结果。结果：与术前相比,对照组的睑缘形态评分、睑板腺分泌物评分显著提高,BUT和SⅠt显著下降。而试验组的术后睑缘形态评分、睑板腺分泌物评分、BUT和SⅠt均较对照组显著改善(P<0.05)。结论：超声乳化手术可以加重合并MGD患者的睑板腺功能,破坏眼表状态,而术前行睑板腺按摩可以显著改善白内障术后MGD患者的眼表状态。

Effect of Meibomian gland massage before phacoemulsification on ocular surface after surgery in patients with Meibomian gland dysfunction

?AIM:To study the changes of ocular surface in cataract patients with Meibomian gland dysfunction ( MGD) who treated with Meibomian gland massage before surgery.?METHODS: Totally 90 patients ( 93 eyes ) with cataract and MGD were randomly divided into two groups. Patients in experimental group were treated with hot compress and Meibomian gland massage every day before surgery, while the patients in the control group were not taken. Two groups of patients received phacoemulsification combined with intraocular lens implantation. Lid margin abnormalities, secretion characteristics, Schimer I test ( SⅠt) and tear film break-up time ( BUT ) were recorded and compared between two groups using slit lamp microscope inspection preoperatively and postoperatively 1wk.?RESULTS:In the control group, the postoperative score of eyelid margin and Meibomian gland secretion was increased significantly than preoperative, while the value of BUT and SⅠt was down significantly. Compared with control group, the postoperative score of eyelid margin shape and Meibomian gland secretion in the experimental group was decreased significantly, while the value of BUT and SIT improved significantly (P<0. 05).?CONCLUSION: Phacoemulsification can aggravate the Meibomian gland dysfunction and have some extent of effects on the ocular surface. Meibomian gland massage before surgery can significantly improve the function of Meibomian gland and the state of ocular surface in patients with MDG.
