The sagittal distance of ocular structures can be obtained with a slit-lamp microscope providing the movement of the slit-lamp can be measured. A simple device consisting of a pointer attached by a spring clip to the axle of a Haag-Streit 900 slit-lamp is described. The pointer rides over a scale which slides with the slit-lamp. Comparisons of anterior chamber depth and lens thickness showed a high correlation between this optical method and ultrasound measurements.
如果能够测量裂隙灯的移动，那么利用裂隙灯显微镜就可以获得眼部结构的矢状距离。本文描述了一种简单的装置，它由一个通过弹簧夹连接到Haag-Streit 900裂隙灯轴上的指针组成。指针在与裂隙灯一起滑动的刻度上移动。前房深度和晶状体厚度的比较表明，这种光学方法与超声测量之间具有高度相关性。
