Research summary
Sight is considered by many as our most important sense. This project is a study of vision problems following stroke. Loss of vision to one side is common following a stroke whereby vision is lost to the right or left side. This visual condition is called hemianopia. Problems that can arise as a result include bumping into objects on the affected side and difficulty with reading. Research has found that some people can still see certain visual targets, for example moving or flickering targets, on their blind side immediately after stroke but these skills are lost over time. Standard testing of the visual field after stroke involves only the use of still / static targets.
In this study we aim for the first time to find out what targets can be seen immediately after a stroke and to see if these skills are lost over time.
We aim to use the results to develop further research into visual training to help improve the visual field area after stroke and other brain injuries.Participants from one site (Salford Royal Hospital) will be involved in this study for 12 weeks. During this time a total of three visits to an outpatient eye clinic will be required (first assessment within 2 weeks of stroke), then 6 weeks and 12 weeks after the stroke. These visits are not additional to the usual routine follow up this condition.
At each visit, the researcher will record all vision information taken from the usual eye examination. Participants will also be asked to undergo two additional visual field assessments as part of the study. One test will involve the use of a flickering target and the other a coloured target. The total additional time to complete both additional assessments is expected to be approximately twenty minutes.REC name
