What is Vision Restoration Therapy?
NovaVision® Vision Restoration Therapy (VRT) is based on groundbreaking research in visual neuroplasticity. VRT is an FDA-cleared, patented, non-invasive medical device that may restore vision in stroke and traumatic brain injury (TBI) patients with visual deficits. While speech, physical and occupational therapies are the long-standing treatment standards for stroke and TBI survivors, VRT is the first FDA-cleared clinical application of rehabilitation for vision loss.
Visual field loss prevents patients from engaging in many normal day-to-day activities. In a recent retrospective study, more than 70 percent of patients who completed VRT showed measurable improvements in their vision that enhanced their quality of life1.

What vision defects can be treated with Vision Restoration Therapy?
NovaVision Vision Restoration Therapy is cleared by the FDA to treat visual impairments caused by stroke, brain injury, brain tumors, and brain surgery.
Vision Restoration Therapy can treat any of the following vision defects:
- Hemianopia (decreased or lost vision in one half of the visual field)
- Quadrantanopia (decreased or lost vision in one quarter of the visual field)
- Scotoma (island of visual impairment)
- Diffuse field defect , including constriction of the field of vision (tunnel vision) caused by a tumor, brain surgery, or brain disorders

Who is eligible for Vision Restoration Therapy?
Most patients with visual field defects such as hemianopia, scotoma and quadrantanopia are eligible for Vision Restoration Therapy and may benefit from the treatment. However, there are certain conditions in which VRT may not be suitable. Those with serious eye disease and significant cognitive deficits may find that their condition interferes with VRT. In addition, we recommend that patients suffering from acute central nervous system or eye disease delay therapy until the acute phase is over.
VRT requires significant concentration and attention. Those with significant cognitive difficulties that would preclude understanding the instructions or maintaining attention for 30 minutes usually are not appropriate candidates for this version of VRT.
If your visual acuity is worse than 20/200, you may not be able to detect the stimuli reliably and therefore you should not complete VRT. Our screening tool is a good indicator of whether you can perform VRT successfully.

Can myopia or farsightedness be treated with Vision Restoration Therapy?
VRT is indicated only to treat visual impairments caused by neurological disorders such as stroke, head injuries, and brain tumors at this time. Refractive errors like myopia, hyperopia, astigmatism, or presbyopia are not treated with VRT.

Does the amount of time since an injury affect whether a patient qualifies for VRT?
The time between the injury and beginning therapy is not significant. There have been many successful outcomes for patients who suffered vision loss decades before receiving the therapy. One such case was that of a World War II veteran who benefited from VRT.

Does vision rehabilitation have any age limitations?
There are no age restrictions for patients interested in vision rehabilitation after suffering a stroke or brain injury. The only requirement is that the patient must be able to concentrate for the hour a day it takes to perform the therapy.

What is the success rate of VRT?
Nearly 90% 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 again2 . A recent retrospective study of 161 patients from 16 medical centers across the US demonstrated that over 70 percent of patients who completed this type of vision rehabilitation showed measurable improvements in their vision fields1. 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. Nearly 88% of patients mention a significant improvement in quality of life1. Learn more about the studies that support these conclusions.

What are some of the improvements patients have described after undergoing vision rehabilitation?
Most of the improvements patients describe after undergoing vision rehabilitation involve reading, walking / mobility, confidence / independence, hobbies, watching TV, and dining out. Patients also report a decrease in injuries from falls and bumps. Fortunately, nearly 90% of patients have mentioned at least one meaningful benefit as a result of VRT2.

Does Vision Restoration Therapy have any side effects?
The majority of patients who undergo Vision Restoration Therapy do not experience any noticeable side effects, though a small number of patients have reported infrequent headaches. If you experience discomfort or strain, you should consult your doctor.

How do I start therapy?
The first step is to call NovaVision Patient Services to verify your candidacy and to locate a prescribing doctor in your area. Once a neuro-ophthalmologist, ophthalmologist, optometrist, neurologist or physiatrist has determined that you are a candidate for VRT and written a prescription, you will pay for three months of therapy so that a VRT device can be sent to your home. You will then complete a series of tests to evaluate your vision deficit. NovaVision then analyzes the test results to create and send you a customized therapy program. You may contact NovaVision by email or call us at 1.888.205.8380 to ask questions or request more information.

How do I perform the therapy?
Vision Restoration Therapy is performed with a VRT device in the comfort of your home. During a 30-minute session, you will focus on a central point on the device screen and respond whenever you see a light stimulus appear. It is recommended to set up the device on a desk or table with a comfortable chair in a quiet, dimly lit room, free of distractions. NovaVision Patient Services is available to help you get started should you need assistance and can be reached by calling 1.888.205.8380. You will also be provided with helpful videos and instructions.

How long does Vision Restoration Therapy take to complete?
Generally it is recommended that patients complete 6 months of twice-daily therapy, however, everyone responds differently to therapy. After the initial 6 months of therapy the patient should be re-evalutated by their doctor to determine if it will be beneficial to continue therapy.

How much does Vision Restoration Therapy cost?
Since therapy is paid for on a monthly basis, the cost of treatment depends on how long the patient needs to perform therapy. Contact NovaVision for more details.

Is Vision Restoration Therapy covered by insurance?
With proper documentation, a number of NovaVision’s patients have had success gaining insurance coverage for therapy from several carriers. This may take persistence, but may result in either full or partial reimbursement of the cost of your therapy. To submit a claim or an appeal, we recommend completing and sending the following information:
Call NovaVision for assistance in submitting a claim for consideration at 1.888.205.8380. You can download the steps for requesting coverage of VRT from your insurance provider by clicking here.

How is my therapy program determined?
Once it is determined that you are a candidate for Vision Restoration Therapy you will take several tests on the VRT device that will map your area of visual impairment. From these initial tests NovaVision will determine the location of the borders of the visual deficit, and how to target them with therapy. Your therapy regimen will be updated regularly based on your progress and the status of your deficit.

During my therapy when should I see my doctor?
NovaVision will continually monitor your deficit and your progress. After 5 months of treatment, it is recommended to meet with your doctor to determine if you should continue with therapy beyond the typical 6-month course. To learn more, please read the details of how VRT works.

How does VRT improve vision through the brain?
There is brain reorganization that results in visual field improvement. The precise mechanisms of brain reorganization are being studied. Some researchers hypothesize that visual neuroplasticity works through the activation of other visual pathways that were previously unused, and the use of localized attention. Learn more about the studies that support these conclusions.
