Photoreceptors are cells in the retina which convert light into nerve impulses. Because of them, we can see the world around us. The two types of photoreceptors are rod cells and cone cells. Rod cells are responsible for peripheral and night vision, and cone cells are responsible for central and color vision under bright conditions. […]
Support groups for people with blindness and low vision are important monthly events in hundreds of senior centers, clinics, retirement communities, and other venues for older adults. Recent public health concerns, however, are causing worries about attendance at these gatherings. MD Support has announced that its telephone support group, TeleSupport, is welcoming guest callers during […]
Pixium Vision reports that follow-up from 18 to 24 months after implantation showed that their PRIMA Bionic Vision System sustainably elicited light perception in all four dry AMD patients with favorable safety profile. Moreover, the second-generation transparent glasses, enabling to combine natural peripheral vision and prosthetic vision, greatly benefited patients and their visual acuity by 3 […]
Many doctors are restricting clinic visits to urgent or emergent problems during the coronavirus pandemic. Are anti-VEGF injections considered urgent? What qualifies as an emergency? Should I let my eye physician know if I am showing symptoms of COVID-19? I’m in a clinical trial. Should I continue to participate? Prevent Blindness provide answers to these […]
Nano Retina has announced preliminary results for first-in-human implantation of its NR600 artificial retina device. The first two patients to receive the device in March 2020 reported visual effect. The NR600 mimics the natural physiological processes of the human eye and restores functional vision to persons blinded by retinal degenerative diseases, including age-related macular degeneration […]
“Social distancing? Not a problem,” remarked an elderly member of my low vision support group. “I’ve been socially distant for years.” “Absolutely,” said another. “The toughest issue with being alone was originally what to do to fill my time, but I’ve gotten pretty good at that.” The session then took a detour from my planned […]
A Summary of a Quarter-Century of Low Vision Research and Development Presented to the International Low Vision Support Groupby Dan Roberts, Director Macular Degeneration Support, the charitable parent corporation of our International Low Vision Support Group, is celebrating its 25th year as a leading resource for people affected by macular degeneration and similar diseases leading […]
Information from the National Eye Institute A protein that normally deposits mineralized calcium in tooth enamel may also be responsible for calcium deposits in the back of the eye in people with dry age-related macular degeneration (AMD), according to a study from researchers at the National Eye Institute (NEI). This protein, amelotin, may turn out […]
Patients who are undergoing anti-VEGF treatment with Beovu (brolucizumab) for wet AMD should be aware that the drug is currently being investigated by the drug’s manufacturer, Novartis, for potential adverse events in some patients. Beovu was approved for clinical use in October 2019, and it has since shown to be an effective and long-lasting inhibitor […]
A study concluded in 2019 suggests that some patients with wet AMD can retain good visual acuity with no treatment for at least 3 years after stopping anti-VEGF treatment. Researchers compared two groups from the 2008-2009 Comparison of Age-Related Macular Degeneration Treatments Trials (CATT). The first group was comprised of patients who had been released […]
