In the retina, the cells responsible for the visual experience are rods and cones. These cells are called photoreceptors and they absorb and convert light into electric signals.

The two types of photoreceptor cells are known as rods and cones. Rods are responsible for peripheral and night vision. They detect brightness and shades of gray. Cones are responsible for day vision ...

These recordings revealed that the remaining cones in a retina where the rods have mostly degenerated were still functional. Although the anatomic specializations that are responsible for ...

No cases of retinal vasculitis were reported in any of the groups, he said. “What’s most meaningful about this study is ANX007 protection from vision loss and its safety,” Khurana said.

At low levels of luminance visual acuity is probably limited by the rate at which light quanta activate the retinal receptors2, and thus a large pupil admitting the maximum amount of light would ...

In the study, the mean change from baseline in best corrected visual acuity was -0.21 logMAR (90% CI -0.45 to 0.02) in the study eyes and -0.01 logMAR (90% CI -0.09 to 0.06) in the untreated ...

Rods and cones studding the retina can work in tandem to give an animal good vision in a wide variety of light conditions. Some species that live in dark environments, like many deep-sea fish ...
