How does VRT work?

Vision Rehabilitation Post Stroke or Brain Injury – Understanding the Process of VRT

Developed by NovaVision and based on decades of research. Vision Restoration Therapy consists of three components: evaluation and diagnostic, treatment, and results.

Evaluation and Diagnostic

The first step to improving your vision and enhancing your quality of life is to have a doctor evaluate your deficit and see if you are an appropriate candidate for Vision Restoration Therapy. If you need assistance finding a doctor qualified to do so, visit the VRT Directory or contact NovaVision on 1.888.205.0800. To start the therapy, you will perform a few tests that will help NovaVision clinicians create a customized vision rehabilitation therapy specific to your condition for you to perform at home.

In order to start your therapy you must have a prescription and eye exam form completed by your physician. To download these forms please click here.


VRT involves no surgery or medication of any kind and the therapy is completed at your home. VRT consists of daily therapy sessions on a computer in which light stimuli are presented along the border between the seeing area and the blind area in order to stimulate visual functions and expand the field of vision. It is prescribed in time intervals based on individual needs and abilities. VRT is prescribed to be performed six days a week for a period of up to six months.

Performing VRT

You perform your vision rehabilitation therapy sessions seated in front of a computer screen and with your head held in a NovaVision-supplied chin rest, ideally in a relatively dark room free of distractions. Throughout the vision rehabilitation sessions, you will focus your eyes on a central point displayed on the computer screen and respond whenever you see a stimulus that will be mostly presented along the border of the blind area. To get an idea of what therapy entails and the look and feel of it, take the online vision test.


For every month of vision rehabilitation NovaVision will evaluate your results and update your therapy for the following month to optimize your progress. Typically, patients who require vision rehabilitation after a brain injury or stroke need time for impaired brain functions to recover. After most injuries, therapy can help restore function.

Vision Therapy Progress

As with any rehabilitation program, consistent use of VRT on the part of the patient is required. Vision rehabilitation post stroke or brain injury is gradual, though for some patients the first improvements are noticeable as early as a few months after therapy begins. In a retrospective study of Vision Restoration Therapy, more than 70 percent of patients who completed VRT showed improvements in their vision and reported an enhanced quality of life.1
