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, ...

After taking a neuroscience or biology course, most students have heard about rods and cones. But what about the recently discovered third class of photoreceptor cells in the retina - intrinsically ...

“The non-invasive in vivo optical imaging of rhodopsin activation extends the diagnostic capability of ORG and may facilitate ...

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 ...

Light-sensitive cells in the retina come in two main types: rods and cones. Rods are used for vision at low light and cones for color and bright light. A study in the September issue of the Journal of ...

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 ...

Like ours, the fish visual system relies on light-sensitive receptors in the retina called rods and cones: Rods for twilight vision, cones for daylight vision. Researchers examining a 300-million-year ...

A 22-year-old man was referred with decreased visual acuity of 4 years duration and bilateral ‘positive’ scotomata. Past medical and ocular history was unremarkable. Visual acuity (VA) was 0.30 logMAR ...

CHICAGO — An investigational drug that would potentially be the third approved treatment for people with geographic atrophy has demonstrated a signal the two approved treatments have not: An ability ...

Scientists are shedding new light on the importance of light-sensing cells in the retina that process visual information. The researchers isolated the functions of melanopsin cells and demonstrated ...

Light-sensitive cells in the retina come in two main types: rods and cones. Rods are used for vision at low light and cones for color and bright light. A study in the September issue of the Journal of ...
