Cones outnumber rods only in the center of the retina, which is the area of greatest density. It is also the area most heavily used by daytime, direct vision. But rods do fire during the day, ...

Scientists at the Jules Stein Eye Institute at the David Geffen School of Medicine at UCLA have discovered that certain ...

New research shows that retinal neurons can rewire to preserve vision in retinitis pigmentosa, a genetic disease causing blindness.

Researchers have developed a noninvasive technique that can capture images of rod and cone photoreceptors with unprecedented detail. The advance could lead to new treatments and earlier detection ...

A fish fossil suggest rods and cones, the two main components of modern vision, have been around for more than 520 million years.

Scientists have discovered a fossilized fish with its well-preserved eyeball containing rods and cones that are visible under a microscope. The discovery of the 300 million-year-old fish eye ...

Scientists have discovered a fossilized fish so well preserved that the rods and cones in its 300-million-year-old eyeballs are still visible under a scanning electron microscope.

Scientists have reported that the tiny light-sensing cells known as rods have been clearly and directly imaged in the living eye for the first time. Using adaptive optics, scientists can see ...

We investigated the cone- and rod-mediated mfERG in 17 eyes of 17 subjects with early ARM and 16 eyes of 16 age-matched control subjects with normal fundi.
