[Current etiological aspects of papilledema].

Twenty-eight patients with papilloedema have been observed on twenty-thousand patients. In one third of the cases, they were associated with an hypertensive retinopathy. Another third was symptomatic of an expansive intra-cranial process. Otherwise, we only find a papilloedema in one case of eight with an expansive intra-cranial process. If a lot of them stay idiopathic and can regress without complication, it is necessary to look after them regularly, the secondary discovery of a cerebral tumor is not exceptional at all.
