Eye

As is the case with so many other things, the sooner that Alzheimer's disease is detected, the more that can be done to slow its progress. An experimental implantable lens could help, by changing in appearance at the early stages of the illness.

Scientists have grown mini eyes from human cells in the lab. These eye organoids provide good models of the real thing to help scientists study diseases that cause blindness and potentially find treatments.

A team of researchers in the UK has developed a fully automated artificial intelligence-enabled system that can scan retinal images for vascular health, helping identify those at high risk of heart disease and stroke.

When crossing the road in front of a car, pedestrians should make eye contact with the driver, to make sure they've been seen. However, what if the car has no driver? New research suggests that the vehicle should then have eyes of its own.

New research points to an eye response to light as a potentially useful way of diagnosing autism in young children. Further testing is underway in a large cohort of children and a simple device to screen pupil responses has been developed.

A cornea implant made out of collagen gathered from pig skin has restored the vision of volunteers in a landmark study. Pending further testing, the novel implant is hoped to improve the vision of millions waiting for difficult transplant surgeries.

Scientists studying the aging process in the eye have made an important discovery around the role of a so-called "youth" protein, and shown how it promotes a healthy recycling process that maintains our vision.

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.

When you view the image above, does it look like black smear in the center is expanding? If it does, that means you're like most people – and your brain may even think that you're entering a tunnel, adjusting your eyes accordingly.

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.

A prototype smartphone app has been developed to screen for the very earliest stages of Alzheimer’s disease. The app tracks minute changes in a person’s pupil size, which previous research has shown can indicate pre-clinical neurological disease.

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.
