A method of image analysis for primary angle closure glaucoma.
Abstract
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.
