Abstract:
The pupil reactions in young subjects with emmetropic and myopic refraction, in normal subjects aged over 40, and in patients with primary open-angle glaucoma (POAG) are analyzed in relation to the trophic changes in the iris and functional activity of the ciliary muscle. These processes course in parallel with each other, but in POAG the changes in the pupil reaction are preceded by dystrophy of the iris and ciliary body, which is due to a slower conduction of pulses via the conduction routes. This permits the use of pupilography for early diagnosis of POAG.
