New Discovery May Lead to Better Eye Disease Screening
Australian scientists may have made a discovery that could lead to the development of better tests to detect eye diseases like glaucoma and macular degeneration. Research published in the Journal of Vision suggests that color sensing cells in retina, which were previously believed to be able to only respond to specific colors, can also detect black and white moving objects as well. According to lead researcher Paul Martin: “For a long time we’ve had an image of the brain as a kind of computer, with particular pathways or ‘wires’ for particular nerve signals. Now, it is becoming clear the wiring is a lot less precise than a computer.”
What might this mean for you when its time to be screened for eye disease? Discoveries like this one help scientists better understand how cells in the eyes respond to stimuli, and the more they know about how the eye works, the more able they are to improve eye testing procedures and technologies.
