Observation of the change in ocular anterior segment after pterygium surgery with ultrasound biomicroscopy

Abstract

AIM: 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. CONCLUSION:The anterior chamber depth and the angle change is not obvious after pterygium excision.
