Study examines how people adapt to post stroke visual impairments – University of Liverpool

A new University of Liverpool study, published in Wiley Brain and Behaviour, examines the factors that influence how a person adapts to visual field loss following stroke.

Approximately 65% of acute stroke survivors have visual impairment which typically relates to impaired central or peripheral vision, eye movement abnormalities, or visual perceptual defects.

Symptoms can include blurred or altered vision, double or jumbled vision, loss of visual field, reading difficulty, inability to recognize familiar objects or people and glare. The factors that influence how a person adapts to a Post stroke visual impairment (PSVI) is currently an under researched area.

In order to profile the full range of influencing factors researchers from the University’s Department of Health Services Research, led principally by Professor Fiona Rowe and Mrs Claire Howard, systematically reviewed data pertaining to PSVI published between 1861 and 2016. This data included randomized controlled trials, controlled trials, cohort studies, observational studies, and case controlled studies.

Researchers identified 47 studies which involved a total of 2,900 participants and categorised them into two sections. Section one included seventeen studies where the reviewers were able to identify a factor they considered as likely to be important for the process of adaptation to post stroke visual field loss. Section two included thirty studies detailing interventions for visual field loss that the reviewers deemed likely to have an influence on the adaptation process.
