Survivors of a stroke or brain injury can have therapy to help them re-learn how to speak or move their muscles again. But what if the part of the brain that affects their vision is damaged?
Well there is something now called Nova-Vision that may be an option for some patients. It's a type of therapy to bring back vision by retraining the brain after a stroke or brain injury.
"By stimulating the remaining parts of the brain that are still active is the potential of re-wiring the brain so function can be maintained," said Lotfi Merabet, OD, PhD, with Beth Israel Deaconness Medical Center.
The Nova-Vision program can be used in a lab or in a patient's home on their computer. Patients focus on spots of light or fixation points. When there's a change on the screen like the spots change color or move, a click of the mouse is all it takes to let the program know you've noticed the change.
Basically, it's an eye exercise. By using the therapy twice a day, five to six days a week, patients can see improvements in their vision as early as three months into the treatment. Although many patients have had great success with Nova-Vision, it is getting mixed reviews because some eye specialists are skeptical.
