Diopsys announced in a press release that research scientists may have found a direct correlation with functional cell loss in the retina and signs of dementia in those with a genetic risk for frontotemporal dementia.
The research from the University of Alabama, Birmingham, Gladstone Institutes, and University of California, San Francisco, was published in the Journal of Experimental Medicine.
According to the press release, the researchers used an electroretinogram as the measuring device in their subjects, which measures the electrical signal activity of ganglion cells. The researchers compared ganglion cell activity in healthy subjects with subjects known to have frontotemporal dementia and found a significant decrease in cell activity in the retina of subjects with dementia.
Diopsys’ NOVA-ERG Vision Testing System enables practitioners to attain information on ganglion cell activity within 28 seconds.
Diopsys is currently working towards creating an entire line of testing modules for the eye care practitioner utilizing ERG and visual-evoked potentials to measure activity in the retina and visual cortex, according to the press release.
