title: [The most important signs of a glaucomatous disc].
abstract: Glaucomatous optic atrophy is the result of both primary and secondary glaucomas leading to functional defects. Loss of axons and ganglion cells leads to a specific atrophy of the optic nerve head. Increased cup size and depth with loss of neuroretinal rim tissue are accompanied by changes of the retinal vessels and juxtapapillary retinal pigment epithelium. Changes of the retinal nerve fibre layer, caused by ganglion cell loss may be earliest signs of glaucomatous atrophy. The marked variability of optic disc size and form may influence the quality of ophthalmoscopic evaluation in extreme variants. Peripapillary haemorrhages and changes of pulsation properties of the retinal venules may give prognostic information for the course of the disease. These signs may be evaluated and even semiquantitatively measured with limited technical effort. They lay the basis for the evaluation of modern imaging and measuring techniques. This article summarises criteria described by Jonas and other authors in the light of modern imaging techniques and adds the latest scientific results.
