[Vascular pseudopapillitis (author's transl)].

Besides the true ischaemias of the optic nerve, which explain the post-haemorrhagic amaurosis, the low tension glaucoma and the open angle glaucoma, there are two varieties of vascular pseudopapillitis. First the variety due to arteriosclerosis, which is characterized by a palid oedema of the disc, followed by optic atrophy, a diminution of the vision field, as well as by signs of arteriosclerosis at the biopsy of the temporal artery. The second variety is the temporal arteritis, which is also characterized by a palid oedema of the disc, followed by optic atrophy, a visual loss, which is often complete, a marked rise of the erythrocyte sedimentation rate and a typical granulomatous arteritis at the biopsy of the temporal artery. These two varieties are due to an involvement either of the short posterior ciliary arteries or of the central vascular or pial system of the optic nerve.
