Brief Summary
The goal of this study is to learn whether NeuroEyeCoach, a computer-based eye movement training programme, can help stroke survivors with visual field loss. The study will also assess whether a larger clinical trial is feasible. The main questions it aims to answer are:
- Can stroke survivors be successfully recruited, randomised and followed up in a larger trial?
- Is NeuroEyeCoach acceptable and practical to use?
- Is there early evidence that NeuroEyeCoach improves vision-related functioning and wellbeing? Researchers will compare NeuroEyeCoach plus usual care with usual care alone. Participants will:
- Be randomly assigned to receive NeuroEyeCoach plus usual care or usual care alone
- Complete six weeks of training if allocated to NeuroEyeCoach
- Complete questionnaires and tests of vision, daily activities, quality of life, confidence and wellbeing
- Take part in follow-up assessments over six months This pilot trial will include 60 stroke survivors living with visual field loss after stroke. Findings will be used to inform the design of a larger study.
