背景：关于超声生物显微镜（UBM）对前房角的发现，发表的数据有限。这项工作提供了一个以人口为基础的评估角度的结果，并比较3种方式来评估角度dimensions.Methods：一个样本的268人谁参加了以人口为基础的研究青光眼患病率在新加坡进行了复查UBM（鼻，颞，下角仅），Scheimpflug摄影的角度宽度，和房角镜检查。结果：UBM显示的3个角中，颞角最宽，下角最窄（比颞角窄近20%，P < 0.005）。发现女性的角比男性窄，老年人的角更窄。Scheimpflug摄影没有提供足够的细节的角度，以增加我们的理解角anatomic.Conclusions：报告的数据支持早期的研究结果，即前房角较窄的老年人和妇女。评估角的方法本身可能影响角的外观。有限的协议之间存在的角度量化方法研究。理想的角度评估方法不会接触眼睛，也不需要将光线对准眼睛。
Background: Limited data are published on the ultrasound biomicroscope (UBM) findings of the anterior chamber angle. This work provides a population-based assessment of angle findings and compares 3 modalities for assessing angle dimensions.Methods: A sample of 268 persons who had participated in a population-based study of glaucoma prevalence in Singapore were reexamined by UBM (nasal, temporal, and inferior angles only), Scheimpflug photography of angle width, and gonioscopy. Angle findings were compared, and age and sex influences evaluated.Results: The temporal angle was the widest of the 3 angles imaged with the UBM, and the inferior angle was the narrowest (nearly 20% more narrow than the temporal angle, P < 0.005). Women were found to have narrower angles than men and older persons had more narrow angles. Scheimpflug photography did not provide enough detail of the angle to increase our understanding of angle anatomy.Conclusions: The data reported support earlier findings that the anterior chamber angle is narrower in older individuals and women. Methods of assessing the angle may themselves influence the appearance of the angle. Limited agreement exists between the angle quantification methods studied. An ideal method of angle assessment would not contact the eye and would not require light be directed at the eye.
