The Dynamics of Transient Cerebral Blindness

Abstract

Although cerebral blindness is well known and has been described in numerous communications,37,28,8 detailed studies, particularly those relating to changes in the visual functions over the course of time, have been limited. Thus the condition of the fields of vision before blindness is rarely known, and the history of the onset is often incomplete. Moreover patients usually have severe mental disturbances which make it impossible to determine whether they are totally blind. When there is residual vision, per-

Acute posterior cerebral circulation syndrome accompanied by serious cardiac rhythm disturbances: A rare but reversible complication following bypass graft angiography

“…CB usually resolves completely within 2 to 7 days, as was the case in our patient [10]. Return of vision is gradual, starting with the perception of light and motion, followed by restoration of form and color vision [11]. Reversibility of the toxicity depends on BBB reconstitution and the rate of clearance of the offending agent [8].…”

Transient Bilateral Blindness in Relation to Subarachnoid Haemorrhage Caused by Spastic Ischaemic Changes in Retina and Optic Nerve

“…Transient blindness has been described before (Walsh & Brown 1964). Further cortical blindness related to angiography of the vertebral and carotid artery or due to ventriculography is well known Udrgensen et al 1970;Rasmussen 1970;Silverman et al 1961;Walsh & Smith 1952). Such cortical blindness is presumably caused by spasms in the posterior cerebral artery, arising few hours after the neuroradiological procedure, usually with visual remission after a few days.…”

Permanent cerebral blindness after cardiac catheterization

“…Mental status changes are common in association with cerebral blindness and are extensively described by Silverman et al [8]. Features include disorientation as to time, place, or person; defective memory; errors in spelling and calculation; persistent bilateral errors on the face-hand test; and denial of the blindness [8].…”

“…Features include disorientation as to time, place, or person; defective memory; errors in spelling and calculation; persistent bilateral errors on the face-hand test; and denial of the blindness [8]. The mental disturbances appear with the onset of the blindness and last from 1 to 3 days, clearing prior to the full recovery of vision.…”
