Rods in the retina contribute to daylight vision

An international research team headed by Thomas Münch from Tübingen University found the contribution of rod photoreceptors in mouse retinas to be much greater than previously assumed. Rods cannot distinguish between colours ...

Immune system found to control eye tissue renewal in zebrafish

Researchers at Johns Hopkins Medicine report evidence that zebrafishes' natural ability to regenerate their eyes' retinal tissue can be accelerated by controlling the fishes' immune systems. Because evolution likely conserved ...

Yin and yang in retinal degeneration

Mutations in the peripherin-2 gene are among the major causes of retinal degeneration. LMU researchers have now discovered why different mutations in the gene preferentially affect one or other of the two types of photoreceptor ...

Why human eyes are wired backwards

The human eye is optimised to have good colour vision at day and high sensitivity at night. But until recently it seemed as if the cells in the retina were wired the wrong way round, with light travelling through a mass of ...

New function for rods in daylight

(Medical Xpress)—Vision – so crucial to human health and well-being – depends on job-sharing by just a few cell types, the rod cells and cone cells, in our retina. Botond Roska and his group have identified a novel ...

Inherited retinal disease research may lead to treatment

Inherited retinal disease is a major cause of vision impairment in early life - and a researcher at The University of Western Australia hopes a study in which he was involved will contribute towards the development of a drug-based ...

Study clarifies process controlling night vision

On the road at night or on a tennis court at dusk, the eye can be deceived. Vision is not as sharp as in the light of day, and detecting a bicyclist on the road or a careening tennis ball can be tough.
