Q&A: Discovery could lead to a cure for glaucoma with nanotherapy

Researchers at the University of Virginia and Northwestern University have created a tool that could help cure glaucoma.

Aging blocks the retina's ability to regrow lost neurons, a first-of-its-kind study finds

A new study from the laboratory of Levi Todd, Ph.D., at Upstate Medical University has found that aging significantly limits the ability of support cells in the retina, called glia, to be reprogrammed into new neurons, a ...

How HIV affects the eyes of aging adults

Older adults with well-controlled HIV may have a higher prevalence of certain eye conditions, particularly dry eye, compared with similar adults without HIV, according to a new study led by a University of Colorado Anschutz ...

Boosting cell cleanup process may protect against glaucoma

Glaucoma is a neurodegenerative eye disease defined by the progressive death of nerve cells in the retina called retinal ganglion cells (RGCs) and damage to the optic nerve. It doesn't have many warning signs, so significant ...

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, ...
