Observation of the change in ocular anterior segment after pterygium surgery with ultrasound biomicroscopy / 国际眼科杂志(Guoji Yanke Zazhi)

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.
