Eye

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.

If diabetes progresses too far, it can result in a potentially blinding condition known as retinopathy. And while existing treatments are invasive and often painful, there may be new hope in the form of an LED-equipped contact lens.

We've looked at many studies and research prototypes demonstrating how contact lenses could be used for more than correcting vision, and a new approval from the FDA has now cleared the way for use of the world's first drug-delivering contact lens.

A new study has uncovered some useful new insights around how physical activity can improve ocular health, suggesting that regular exercise can promote hydration and stability of tear film, helping ward off dry and itchy eyes.
