PAPILLEDEMA ASSOCIATED WITH SUBARACHNOID HEMORRHAGE

Abstract
Papilledema occurs in many but not all cases of increased intracranial pressure. Satisfactory criteria have not as yet been established to differentiate between cases of increased cerebrospinal fluid pressure in which papilledema occurs and those in which it does not. Efforts to set up such criteria follow one of two lines: (1) The important factor is the degree of the intracranial hypertension and its duration. (2) The important factor has to do with the mechanism of the production of papilledema. The present study deals with the occurrence of papilledema in cases of subarachnoid hemorrhage. During the past seven years this diagnosis has been made for eleven patients in the medical wards of this hospital (table 1). In all these cases bloody or xanthochromic spinal fluid was found. In eight cases the pressure was recorded as ranging from 220 to 400 mm. of water. In the three other cases readings of
