The National Library for Health Eyes & Vision Specialist Library presents a short article on Visual field loss after stroke Dr Fiona Rowe, Senior Lecturer, Directorate of Orthoptics and Vision Science at the University of Liverpool. The article was published on 3rd December to coincide with the first annual evidence update on Stroke Rehabilitation being hosted by the NLH Stroke Specialist Library.
Stroke is a vascular event in the brain that is commonly due to a blockage of blood supply (infarction due to thrombus or embolus) or bleed (haemorrhage). 110000 individuals are reported to have their first stroke per year in the UK population with 30000 having a recurrent stroke [1]. Many stroke survivors will have a functional disability following their stroke of which visual disability is just one aspect. One of the commonly recognised visual disabilities is the loss of visual field. Visual field loss is a loss of part of the field of vision. This may occur centrally or peripherally. However, following stroke, loss of visual field is more usually peripheral in nature. Visual field loss is reported as occurring in 20-67%2-8 although some visual field impairment is due to a previous stroke or pre-existent ocular pathology.
