In-vivo sub-diffraction adaptive optics imaging of photoreceptors in the human eye with annular pupil illumination and sub-Airy detection. Optica, 2021; 8 (3): 333 DOI: 10.1364/OPTICA.414206 ...

The newly discovered cells are shaped like twisted tree branches and were found deep inside the retina of a rat's eye. Like the eye's rods and cones, the new cells contain chemicals that react to ...

A statistically significant drop in the cone packing density was observed from 2 to 3° (2° eccentricity=25 350/mm2 (5300/mm2, 8400–34 800/mm2) 3° eccentricity=20 750/mm2 (6000 mm2, 9000–33 ...

The eye has two kinds of photoreceptors that convert light into electrical activity: rods and cones. It is necessary to “divide the labor” between two cell types to enable the eye to see over ...

Cone-rod dystrophy is a group of IRDs that damage cones and rods. Vision loss gets worse over time. Between 1 in 30,000 and 1 in 40,000 people have cone-rod dystrophy.

No one knew whether those information-relaying cells still functioned when the rods and cones were out of service. As the scientists sent pulses of electricity to the ganglion cells, the man ...

Scientists have discovered a 300-million-year-old fossil of a fish species called Acanthodes bridgei. The presence of rod and cone cells in the eyes suggests that the fish had color vision.
