Summary

The goal of this clinical trial is to learn if vision training works to improve functional vision in people with visual field loss after stroke. The investigators want to know more about how people perceive their own functional vision and ability to compensate for visual field loss in daily activities. The main questions the study aims to answer are: * Does vision training improve dimensions of functional vision? * How does vision training affect the participants's perception of functional vision and the ability to compensate for visual field loss? Researchers will compare the effect of home-based vision training to standard care (no vision training) on functional vision. Participants will: * Participate in home-based vision training or standard care for 8 weeks * Be contacted once a week by phone * Keep a training diary

Detailed description

AIM: The overall aim is to obtain knowledge about the effects of compensatory visual rehabilitation strategies on functional vision in people with stroke who do not meet the health prerequisites for visual field, as defined in the Driving licences regulations in Norway. Specifically, to describe the effect on functional vision and the compensatory vision strategies related to traffic situations. Secondary, to explore markers for perceived functional vision and functional visual field that may predict an effect of visual rehabilitation. DESIGN: The study will be performed as an open, controlled and randomized trial with semi-cross-over design. The participants will be allocated to an immediate- or delayed intervention following a pre-randomized list. The participants are allocated to immediate intervention (Fast track; Group A) will be investigated at baseline, after 8 and 20 weeks. The remaining participant are allocated to delayed intervention (Delayed start; Group B) will start the intervention 8 weeks after the baseline and investigated at baseline, week 8, week 20 and week 28. SETTING /RECRUITMENT The study sample will consist of adults with post-stroke visual field defects. All the three sub-studies will have the same study sample.
