Device may improve vision impairments in stroke victims

LTC Liability Monitor, February 20, 2007

The Food and Drug Administration approved a device that uses light stimulation to enlarge the visual field of people who are left with vision impairments after a stroke, according to Reuters. A study looked at 161 stroke patients who were treated at 16 U.S. clinics. The average patient age was 58.7 years old. The patients were seen about three years after a stroke or other brain injury causing impaired vision. Patients underwent Vision Restoration Therapy, which is a custom-designed pattern of bright and dim light stimulation, delivered to the edges of the visual field of the affected eye. Three quarters of the patients improved to some extent, reported Reuters.
