Müller Cells May Restore Sight

Posted in: Latest News, Research and Developments

by Dan Roberts March 19, 2008 Over the past several years, scientists have been taking an interest in certain cells within the patient’s own eyes as having the potential to transform into stem-like (progenitor) cells. Called Müller glial cells, they would then migrate to damaged areas of the retina and replace dead cells, restoring vision

Color Perception and Macular Degeneration

Posted in: Daily Living

Originally published November 2007 People with macular degeneration gradually lose their color perception. This is because the photoreceptor cone cells, which are most dense in the macula, are responsible for color vision. The rod cells, which proliferate in the peripheral field, provide only black and shades of gray. Color is interpreted by the brain. The
