FAQs about Vision Restoration Therapy – Help for Stroke and Brain Injury Patients

NovaVision, Inc. developed Vision Restoration Therapy to help stroke and head injury patients regain their vision, mobility, confidence, and quality of life. Learn the answers to frequently asked questions about the basics of vision rehabilitation, including how long the therapy takes, how it works, and more.

What is the success rate of VRT?

88% of VRT patients surveyed have mentioned at least one significant benefit as a result of performing VRT, such as improved reading, mobility, and in a few cases, driving again¹. A retrospective study of 161 patients from 16 medical centers across the US demonstrated that 76% of patients who completed this type of vision rehabilitation showed measurable improvements in their vision fields². Other studies have produced similar results. As with all therapies individual results vary, and there is no way to predict how you will respond to VRT.

How much vision can I expect to regain?

Clinical data have shown that the average vision gain from VRT vision rehabilitation is a five degree shift in the border of the blind field, which can have an exponential impact on a patient’s daily life. A 5 degree shift in the border of the blind field often leads to better reading, better mobility, less collisions, among other effects. For the majority of patients, the improvement is not sufficient to return to driving, however, quite a few patients have achieved this goal. 88% of patients mention a significant improvement in quality of life.1 Learn more about the studies that support these conclusions.
