应用超声生物显微镜对翼状胬肉术后眼前节结构改变观察

摘要

目的：观察翼状胬肉切除手术后前房深度、房角的变化。方法：原发性翼状胬肉30例30眼行翼状胬肉切除联合角膜缘干细胞移植术,手术前后分别用超声生物显微镜( ultrasound biomicroscopy,UBM)测量术眼中央前房深度以及前房上、下、鼻、颞四个方向的房角开放距离( angle open distance,AOD)及房角开放度数(open angle,AA),并观察眼压。结果：术前与术后的眼压分别为15.17±10.6,16.23±2.61 mmHg；中央前房深度分别为2.28±0.39,2.33±0.24 mm；四个方向的AOD及AA比较均无统计学差异。结论：翼状胬肉切除术后前房深度及房角改变不明显。%AlM: To observe the effect of anterior chamber depth and angle change after pterygium excision.METHODS:Thirty cases (30 eyes) of primary pterygium were underwent pterygium excision. Central anterior chamber depth, four direction angle open distance ( AOD ) and open angle ( AA ) were measured preoperatively and postoperatively by ultrasound biomicroscopy ( UBM ) and the intraocular pressure was observed.RESULTS:Preoperative and Postoperative intraocular pressure were 15. 17±10. 6 and 16. 23±2. 61mmHg, and the central anterior chamber depth were 2. 28±0. 39 and 2. 33± 0. 24mm. The four directions of AOD and AA were no statistical difference.CONCLUSlON:The anterior chamber depth and the angle change is not obvious after pterygium excision.
