Reports from University of Oxford describe recent advances in retinal degeneration
January 11th, 2011
New research, 'Light effects on mitochondrial photosensitizers in relation to retinal degeneration,' is the subject of a report. "The retina captures and converts light between 400-760 nm into electrical signals that are sent to the brain by way of the optic nerve and in the process helps to translate these electrical signals into what is known as vision. The same light that allows vision to occur is nevertheless also potentially toxic to retinal cells in certain situations," investigators in Oxford, the United Kingdom report.
"The shorter wavelengths of light are known to interact with chromophores in photoreceptors and pigment epithelial cells to cause oxidative stress...
