The anterior segment of the eye is displayed on the video monitor using a slitlamp apparatus (slitlamp 75SL, Zeiss, Germany) combined with a video camera and the video image is then analyzed with a computer to convert the optimal image into the true image. The profile of the true image of the anterior eye segment allows us to estimate the pupil-blocking force, which is the posteriorly directed vector exerted in the iris tissue, according to Mapstone's theory. In mensuration by digitizer on 3 occasions from a single video image of a given normal eye, the Pbf was -0.0255 +/- 0.0011 lambda (= Young's module). And the pupil-blocking force of 10 procedures in a given glaucomatous eye was +1.092 +/- 0.018 lambda.
使用裂隙灯装置（德国蔡司75SL裂隙灯）结合摄像机在视频监视器上显示眼前节，然后用计算机分析视频图像，将最佳图像转换为真实图像。根据马斯顿理论，眼前节真实图像的轮廓使我们能够估计瞳孔阻滞力，即施加在虹膜组织中的向后矢量。在从给定正常眼的单个视频图像上用数字化仪进行3次测量时，瞳孔阻滞力为-0.0255±0.0011λ（=杨氏模量）。在给定青光眼眼中10次手术的瞳孔阻滞力为+1.092±0.018λ。
