Core Outcome Measures in Effectiveness Trials

Impact of Visual Impairment after Stroke (IVIS)

General Information

Summary:
This research programme has four objectives:
1) identify different questionnaires available for people to tell us about their visual problems and identify different treatments available for eye movement problems,
2) determine how frequently visual problems occur and what happens over time,
3) identify issues faced by stroke survivors relating to visual problems, and
4) plan a trial of treatments for eye movement problems following stroke. This new study will help us find out what problems people experience with their sight after a stroke, how we can get better at testing for these problems and what we should do to help.
