Among 195 patients with intracranial aneurysms, 32 had papilloedema. This corresponds to 16% (99% confidence limits 10–24). The papilloedema did not vary significantly by sex, age, or site of aneurysm. It was unilateral in 7 cases, corresponding to the side of the aneurysm or haematoma in 6 cases. Papillary prominence was slight and most often was accompanied by varying degrees of haemorrhage. It was not possible to demonstrate a relationship between the vascular hypertension or cerebral vascular sclerosis and the occurrence of papilloedema, nor was there any correlation with the intracranial hypertension, as judged by the occurrence of cerebral haematomas around the aneurysms or intraventricular haemorrhages and arachnoid adhesions on the one hand, and papilloedema on the other. The papilloedema is presumably due to the subarachnoid haemorrhages in the sheaths of the optic nerves. The haemorrhage compromises the central retinal vein in its course through the subarachnoid space and thereby causes stasis of the venous outflow from the disc. This phenomenon could be demonstrated histopathologically and will be described in more detail in a subsequent paper. The operative risk was found to be increased in patients with papilloedema.
