PURPOSE
The anterior chamber structure in the supine position and the prone position was investigated with ultrasound biomicroscopy (UBM) in pseudoexfoliation syndrome (PE).
METHODS
We studied 12 eyes of 12 PE subjects. Patients were placed in the supine position for 30 minutes, after which UBM was performed. The UBM was repeated after 30 minutes in the prone position. Anterior chamber depth (ACD), angle opening distance 500 microns (AOD 500), and angle recess area (ARA) in 4 quadrants were measured.
RESULTS
Following the postural change from the supine position to the prone position, ACD decreased significantly (p < 0.0001). AOD 500 and ARA decreased significantly in the superior (AOD 500: p < 0.05, ARA: p = 0.03) and temporal quadrants (AOD 500: p < 0.0001, ARA: p < 0.0001).
CONCLUSIONS
The anterior chamber structural change was greater in the temporal and superior quadrants in the PE eyes. This corresponds with previous reports that zonular involvement by pseudoexfoliation material is more pronounced temporally and superiorly.
目的
采用超声生物显微镜（UBM）研究假性剥脱综合征（PE）患者仰卧位和俯卧位时的前房结构。
方法
我们对12例PE患者的12只眼睛进行了研究。患者仰卧位30分钟后，进行UBM检查。30分钟后改为俯卧位再次进行UBM检查。测量4个象限的前房深度（ACD）、500微米处房角开放距离（AOD 500）和房角隐窝面积（ARA）。
结果
从仰卧位变为俯卧位后，ACD显著降低（p < 0.0001）。上方象限（AOD 500：p < 0.05，ARA：p = 0.03）和颞侧象限（AOD 500：p < 0.0001，ARA：p < 0.0001）的AOD 500和ARA显著降低。
结论
PE患者眼睛的颞侧和上方象限前房结构变化更大。这与之前关于假性剥脱物质对悬韧带的累及在颞侧和上方更明显的报道相符。
