The visual system adapts to the loss of photoreception by increasing sensitivity but simultaneously becomes deleteriously hyperactive. The findings could lead to new therapies to protect vision or reverse vision loss.
Researchers developed a new method for producing high numbers of human photoreceptor cells. The human photoreceptor cells can be transplanted in bulk to partially degenerated mouse retinas and improve the detection of daylight in mice with damaged eyesight.
If the circadian clock is disrupted, we might be at greater risk of retinal degeneration as we age.
Novel artificial intelligence software can provide a precise assessment of the progression of geographic atrophy. The technology can also determine the integrity of photoreceptors and detect progressive degenerative changes beyond the main lessons associated with GA.
Researchers have identified a circuit in the brains of fruit flies, which enables them to see in color. The network is similar to that which allows human color vision. The findings could help in the development of AI technologies.
Light sensitive cells in the fetal retina communicate as part of an interconnected network, giving the retina more light sensitivity during development that previously believed.
Researchers use nanotech to enhance vision in mice, enabling them to see infrared light as well as visible light.
Contrast sensitivity may be a result of small eye movements people may not be aware they are making, a new study reports.
Using human retinal tissue grown from stem cells, researchers shed light on how color vision develops. The study found thyroid hormones dictated whether the cells became blue, green or red photoreceptors.
A new study from Tokyo Institute of Technology researchers provides insight into neural networks in the developing brain.
Omega 3 fatty acids and DHA can help photoreceptors and RPEs to survive damage or disease, helping to protect vision.
Researchers use coherent control to control the function of a living cell.
