[Photography of the optic disc in the management of glaucoma (author's transl)].

Repeated photography of the optic disc is helpful in the management of 1. patients with glaucoma, especially those who do not give reliable results on visual field testing, and 2. patients with ocular hypertension. The changes to be looked for are; a) any increase in the size of the cup, b) any decrease in the width of the rim of tissue between the edge of the cup and the edge of the disc, c) the occurrence of small haemorrhages on the disc, d) changes in the course of vessels on the disc.
