Brief Summary
In Denmark, about 120,000 people suffer from brain damage, of whom approx. 75,000 with brain damage after stroke. Serious and often lasting vision impairments affect 20% to 35% of people after stroke. Vision is the most important sense in humans, and even smaller permanent injuries can drastically reduce quality of life. Vision impairments after brain damage inhibits rehabilitation and enhances other invalidating effects. Reduced vision results in impaired balance, increased risk of serious falls, increased support needs, reduced quality of life, and impaired ability to perform activities of daily living. Restoration of visual field impairments occur only to a small extent during the first month after brain damage, and therefore the time window for spontaneous improvements is very limited. Hence, brain-impaired persons with visual impairment will most likely experience chronically impaired vision already 4 weeks after brain injury and the need for visual compensatory rehabilitation is substantial. Neuro Vision Technology (NVT) is an supervised training course where people with visual impairments are trained in compensatory techniques using special equipment. Through the NVT process, the individual's vision problems are carefully investigated and personal data is used to organize individual training sessions that practice the individual in coping with situations that cause problems in everyday life. The purpose of this study is to investigate whether rehabilitation with NVT can cause significant and lasting improvement in functional capacity in persons with chronic visual impairments after brain injury. Improving eyesight is expected to increase both physical and mental functioning, thus improving the quality of life. Participants included in the project will be investigated in terms of both visual and mental functions, including quality of life, cognition and depression. Such an investigation has not been performed previously and can have a significant impact on vision rehabilitation both nationally and internationally.

Eligibility Criteria
You may qualify if:
- years or older with brain injury.
- Persons who experience significant vision impairment.
- Eye sight 6/18 or better.
You may not qualify if:
