NovaVision Study Presented at the American Academy of Neurology Annual Meeting Shows
Functional Improvements for Traumatic Brain Injury and Stroke Patients.
April 28, 2009 – Seattle, WA – NovaVision, Inc. (www.novavision.com) presented data at the
American Academy of Neurology (AAN) 61st Annual Meeting showing functional improvement
in reading and trail-making for 39 study participants with a homonymous visual field defect who
performed at least 6-months of VRT. The Trail Making Test-Part A (TMT-A), a standardized
test of visual search and motor speed, and a reading test were performed to assess study
participants’ reading speed and visuomotor functions. Reading speed improved by 21.6% and
TMT-A completion time improved 34.5%. Study goal was to examine functional outcomes
following traumatic brain injury and stroke.
Consistent with previous studies, study patients showed a similar increase in stimuli detection
following VRT, thus confirming the dependability of these outcomes. The data noted a 10.4%
absolute improvement in stimulus detection during visual field testing.
“The results further validate that VRT is a reliable visual rehabilitation intervention for
functional improvement outcomes regardless of age or time from incident of injury,” stated Jose
Romano, M.D., Associate Professor Neurology, Director of the Cerebrovascular Division at the
University of Miami, who presented the study. “Because the absolute improvement in stimulus
detection is consistent with other studies, we can now see an objective correlation between visual
field expansion and functional ability as a result of VRT.”
Rudy Mazzocchi, President and CEO, stated,” We are pleased to be able to provide patients and
healthcare providers with more information about the benefits of NovaVision VRT. Potential
patients and prescribing clinicians can now review research data that verifies improvements in
daily living activities in addition to visual field expansion as a result of performing VRT.”
NovaVision VRT is the first and only FDA-cleared medical device or rehabilitative therapy
clinically proven to expand the visual field for stroke and brain injury survivors who have been
left partially blind from their injury. VRT is an at-home, customized therapy, which presents
neuro-stimulation in the border along the individual’s blind field.
