Permanent damage to the brain from loss of blood supply. Most occur due to thrombosis within the blood vessels supplying a portion of the brain or less commonly from haemorrhage from those blood vessels. Similar damage may also be caused by tumours or infection. Its relevance to the eye is due to potential damage to the nerves from the eye to the brain, the visual part of the brain itself, and the nerves that control eye movements.
Transient ischaemic attack (TIA) refers to features of a stroke that resolve fully within 24 hours.
