[Study on the dynamic examination of anterior chamber angle by ultrasound biomicroscopy]
1Zhongshan Ophthalmic Center, Sun Yat-sen University of Medical Sciences, Guangzhou 510060, China.
Purpose:
To study the factors that influence ultrasound biomicroscopy(UBM) examination on anterior chamber angle, and explore a dynamic differentiating method.
Method:
To compare the UBM morphologic characters of the anterior chamber angle of the high-risk chamber angle and adhered angle groups under different illumination.
Result:
Under routine working condition, some eyes of the high-risk-group (9/12) displayed bombing iris with extremely narrowly-opened angle; but 3/12 cases and the control group showed bombing iris and closed angle. Under bright circumstances, all angles of the high-risk group showed widely-opened, but the control group remained closed.
Conclusion:
Different illumination influences the UBM examination of the anterior chamber angle significantly, we should differentiate the angle morphologic characters under different illumination if it seems to be closed. Factors that affect the UBM examination were also discussed.
