Scientists have long believed that the eye uses the retina’s rod cells for vision at night and cone cells to see during the day. New research at The Ohio State University Medical Center, however, ...

Share on Pinterest New research involving cones and rods in the retina could lead to new treatments for vision loss. Gregory Adams/Getty Images Cone photoreceptors in retinal degeneration have been ...

Researchers identified a retinal disease to evaluate the success of gene and cell replacement therapy. In the retinas of human eyes, the cones are photoreceptor cells responsible for color vision, ...

Vitamin A is converted to 11-cis-retinal which then combines with scotopsin to form rhodopsin in the rods. If there is a lack of vitamin A, adequate amounts of rhodopsin cannot be produced, thus ...

In other rare retinal disorders, such as Stargardt disease, mutations affect genes related to the cones or the macula, which ...

In addition to allowing us to see, the mammalian eye also detects light for a number of “non-visual” phenomena. A prime example of this is the timing of the sleep/wake cycle, which is synchronized by ...
