...ked by the gradual degeneration of the specialized photoreceptor cells that line the retina along the back of the eye. These cells, better known as rods and cones, translate light that enters the eye into nerve impulses that travel to the brain for interpretation "The million dollar question in retinitis pi...Brown researchers find new photoreceptor and visual system in the eye

What we didnt know until now was what sort of photoreceptor system still operated. In experiments, the researchers injected a fluorescent dye into the tiny part...Optic nerve disease may cause sleep disorders
...Gelder found that the retina contains not only the photoreceptor cells called rods and cones, which translate light into vision, but it also houses non-visual photoreceptor cells called intrinsically photosensitive retinal ganglion cells (ipRG cells) that function as the e...Livermore scientists join DOE consortium

Engineers from LLNL's Center for Micro- and Nanotechnology specifically are developing a flexible silicone implant...DOE labs, universities and second sight partner to speed development of 'artificial retina'
...from the eye to brain is intact, but the eyes lack photoreceptor activity. The artificial retina is a device that captures visual signals and sends them to the brain in the form of electrical impulses. The device is a miniature disc that contains an electrode array that can be implanted in the back of the eye to ...University of Utah study suggests cellular waste to blame for a form of blinding eye disease

... necessary for the nourishment of adjacent retinal photoreceptor cells. As these photoreceptors die in and around the macula, central vision is lost. Peripheral vision is not impaired by AMD. There are two forms of AMD, the more common "dry" form and the less common "wet" form. The wet form can rapidly lead to bli...
