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 ...

Lab-grown retinal cells show promise for new eye therapies

Biomedical engineers at Duke University have used induced pluripotent stem cells (iPSCs) to grow specialized blood vessel cells critical to retinal health for the first time. When injected into mouse models of retinal disease, ...

Faded letters, early warnings: A new clue for aging eyes

Struggling to read more than six lines on an eye chart with fading letters may serve as a visual "yellow light" for older adults—raising red flags that routine exams sometimes fail to detect. A new University of Michigan ...

A global push to recognize the threat of toxoplasmosis

One-third of the world's population is infected with the Toxoplasma parasite, which can cause ocular toxoplasmosis, an eye infection that can damage the retina and result in permanent vision loss. Although often seen as an ...

The mystery of the eye disease that can blind infants

The eye disease known as retinopathy of prematurity (ROP) can make infants permanently blind if they are not treated. But there are big differences in how often Norwegian hospitals actually provide this treatment. "These ...
