A meta-analysis finds that vision impairment and blindness are tied to an increased risk of mortality, prompting the need to address global eye health disparities.
A team of EPFL engineers has developed technology that could partially restore vision in blind people.
This study of more than 526,000 procedures across 17 institutions reports a significant decrease in the use of lasers and cryotherapy, retinal detachment repairs and other vitrectomies, beginning mid-March last year and lasting at least until May.
Using reverse transcription-polymerase chain reaction testing, this study found that SARS-CoV-2 was present on the ocular surface in 52 of 91 patients with COVID-19 (57.1%). The virus may also be detected on ocular surfaces in patients with COVID-19 when the nasopharyngeal swab is negative.

Imagine seeing the world in muted shades -- gray sky, gray grass. Some people with color blindness see everything this way, though most can't see specific colors. Tinted glasses can help, but they can't be used to correct blurry vision. And dyed contact lenses currently in development for the condition are potentially harmful and unstable. Now, in ACS Nano, researchers report infusing contact lenses with gold nanoparticles to create a safer way to see colors.
A newly-published work highlights the long-term ocular health of children wearing daily disposable soft contact lenses and reports minimal impact on physiology over six years. Its results affirm that such lenses are an option for children as young as eight years old. Across the entire study period, there were no contact lens-related serious adverse events, and the low incidence rate of corneal infiltrative events were the equivalent of 6.1 per 1,000 wearing years.
Researchers at UC San Diego Health see a possible way to detect heart disease through the eye.
High-resolution imaging and 3D computer modeling show that the dendrites of neurons weave through space in a way that balances their need to connect to other neurons with the costs of doing so. The discovery emerged as researchers sought to understand the fractal nature of neurons as part of a project to design fractal-shaped electrodes to connect with retinal neurons to address vision loss due to retinal diseases.
There's more to taste than flavor. Let ice cream melt, and the next time you take it out of the freezer you'll find its texture icy instead of the smooth, creamy confection you're used to. Though its flavor hasn't changed, most people would agree the dessert is less appetizing.
