Deep learning refines how bionic eyes communicate with the brain

Researchers from three institutions, including UC Santa Barbara, have demonstrated that artificial intelligence has the potential to make future visual prostheses, like a bionic eye, more precise, predictable and responsive ...

Erectile dysfunction drug used to treat enlarged prostate symptoms may raise glaucoma risk

An erectile dysfunction drug that is also used to treat symptoms, such as sudden urgency and frequency, associated with an enlarged prostate in men may heighten the risk of glaucoma, a serious eye condition, a large comparative ...

Renal impairment linked to age-related macular degeneration

Renal impairment and age-related macular degeneration (AMD) are interrelated, with higher odds of AMD among individuals with chronic kidney disease (CKD), according to a review published in the American Journal of Ophthalmology.

Hidden 'recycling system' helps keep vision cells healthy

For decades, scientists believed that photoreceptors in the retina relied primarily on neighboring support cells, known as the retinal pigment epithelium (RPE), to remove waste. While the RPE is still responsible for clearing ...

Human study links reduced inflammation to later myopia onset

University of Oklahoma College of Medicine researcher Jody Summers, Ph.D., has long hypothesized that inflammation plays a role in the development of myopia, or nearsightedness, in which close-up vision is clear but distance ...

Researchers discover the eye's hidden cleanup system

Many of the world's leading causes of irreversible blindness, including glaucoma and age-related macular degeneration, share a common problem: the buildup of fluid, waste and inflammatory debris in the back of the eye.

Patient-specific 3D-printed contact lenses in just 20 minutes

A breakthrough combination of new silicone materials and advanced 3D printing technology developed by University of Waterloo researchers could transform how contact lenses are manufactured. The study, "Patient-specific hard ...

Low-dose eye drops can manage adult myopia for 24 hours

Groundbreaking research from the University of Houston shows that a single low-dose atropine eye drop can produce daylong effects in managing myopia, or nearsightedness, which affects roughly one-third of U.S. adults. Professor ...

Seeing keratoconus earlier with light polarization and AI

Keratoconus is a progressive eye disease that weakens and thins the cornea, the clear front surface of the eye. In its early, subclinical stage, the cornea can still appear normal on routine exams. Yet this is when accurate ...

'MitoCatch' delivers healthy mitochondria to diseased cells

Scientists led by Botond Roska at the Institute of Molecular and Clinical Ophthalmology Basel (IOB) have developed MitoCatch, a system that enables targeted delivery of healthy mitochondria to specific cell types affected ...

How blind people map their surroundings using sound

Some blind people use returning echoes from their own mouth clicks to perceive external surroundings, or echolocation. New from eNeuro, Haydee Garcia Lazaro and Santani Teng, from Smith-Kettlewell Eye Research Institute, ...
