Scientists in Europe have discovered a molecular “zipper” mechanism that can lead to cell death in the genetic disease retinitis pigmentosa. The good news is that injecting certain proteins could slow or prevent vision impairment from the disease.

Cataracts are one of the most common forms of vision impairment, and unfortunately surgery is the only real treatment. But the clouds may be parting on a new drug treatment, improving the vision of the majority of mice it was tested on.
-
Scientists have found that an existing drug, already used in humans, could help restore vision lost to conditions like age-related macular degeneration and retinitis pigmentosa. The discovery could also lead to a whole new class of drugs.

Yale researchers have found evidence that worms can detect the color blue – even though it doesn’t have eyes or any kind of visual system. In tests, the team found that the color of harmful bacteria influenced whether or not the worms avoided them.

One common symptom of multiple sclerosis (MS) is vision impairment, and it can progress to blindness in some cases. Now, researchers at the University of California, Riverside report a drug that was able to reverse that vision loss in mice.

Researchers in Australia are claiming an important breakthrough in glaucoma research, demonstrating how the degenerative condition can be treated using an innovative form of gene therapy that repairs damaged optic nerve cells.
-
Scientists in the UK have been putting an AI to the test for diagnosing glaucoma, with the results of the trial indicating it can pick up on progression of the disease 18 months earlier than current methods.

One would think that having normal 20/20 vision is due mainly to the anatomical characteristics of the eye. According to a new study, however, tiny eye movements play a large role – and the findings could lead to new treatments for poor sight.

The subjective sense that time moves faster as we get older is a universal one, and over the years scientists have proffered a number of different explanations as to why this happens. A new and strange hypothesis attempts to explain the phenomena, and it has to do with our aging brains.

As far as we know, the largest bird of all time was the now-extinct elephant bird. The flightless animal stood over 10 feet tall (3 m), and was native to Madagascar. Little is known about how it lived, although new research indicates that it was likely nocturnal, and had little if any eyesight.

Repairing people's sense of sight by way of retinal implants is a field of research that is seeing some rather promising advances. Now researchers say they have broken new ground in the area, which brings with it the prospect of more successful integration in the human body.

Researchers have been able to restore partial vision in mice by regenerating previously severed optic-nerve cables. It’s the first time researchers have succeeded in restoring important aspects of vision in mammals, and the breakthrough could lead to future work that restores sight in the blind.
