NIH Discovery Brings Stem Cell Therapy for Eye Disease Closer to the Clinic

Scientists at the National Eye Institute (NEI), part of the National Institutes of Health, report that tiny tube-like protrusions called primary cilia on cells of the retinal pigment epithelium (RPE)—a layer of cells in the back of the eye—are essential for the survival of the retina’s light-sensing photoreceptors. The discovery has advanced efforts to make […]

Scientists Find Therapeutic Target for Diabetes-Related Blindness

Study reveals single cell type and surface molecule sufficient to cause common complication Specific cells in the retina trigger inflammation and vision impairment associated with diabetes, according to new research out of Case Western Reserve University School of Medicine. The findings unexpectedly implicate Müller cells—which provide structural support in the retina—as key drivers of the […]

In-Home Occupational Therapy Curbs Depression in Visually Impaired Patients

Depression is common in patients with central vision loss, but study suggests that low vision rehabilitation and occupational therapy could decrease its severity Johns Hopkins researchers report that in-home occupational therapy appears to reduce the rate and severity of depression in people at higher risk for the disorder because of seriously impaired vision. The Centers […]

Researchers Develop Best-Yet Cell Culture System for Age-Related Macular Degeneration

An international team from the University of Alabama at Birmingham and University College London and Queens University Belfast in the United Kingdom developed a cell culture model that could help to develop earlier treatment strategies for age-related macular degeneration, the third most prevalent cause of vision loss worldwide. In AMD, which is twice as prevalent […]
