A new computerised method of measurement of the anterior chamber in the human eye is described. Photographs of the anterior chamber were taken with a Zeiss slit-lamp 75-SL and converted from an optical image into a true image by computer with a digitiser. We obtained data on both the anterior chamber volume and also the anterior chamber depth, peripheral anterior chamber volume, the diameter of the anterior chamber, and the degree of the iridocorneal angle. These data were simultaneously displayed several seconds after in-put by the digitiser. In mensuration by digitiser on three occasions from a single photograph of a given eye the mean deviation rate was about 0.7%, and the mean deviation rate of 10 successive exposures of one eye was 3.5%. By this image analysis technique an accurate profile of the anterior chamber is displayed of the pupil margin, iris-root insertion, and central anteroposterior pupillary axis. These data help us to understand the mechanism of primary angle-closure glaucoma.
本文描述了一种测量人眼前房的新型计算机化方法。使用蔡司75-SL裂隙灯拍摄前房照片，并通过带有数字转换器的计算机将光学图像转换为真实图像。我们获得了前房容积、前房深度、周边前房容积、前房直径以及虹膜角膜角度数的数据。这些数据在数字转换器输入后几秒钟内同时显示。在对同一只眼睛的单张照片进行三次数字测量时，平均偏差率约为0.7%，而对一只眼睛连续10次曝光的平均偏差率为3.5%。通过这种图像分析技术，可以显示出瞳孔边缘、虹膜根部附着点和瞳孔中央前后轴的准确前房轮廓。这些数据有助于我们了解原发性闭角型青光眼的发病机制。
