Healthy vision is essential for interacting with the world. Without it, kids face slowed development, adults can encounter employment and mental health difficulties, and seniors become more vulnerable to social isolation, accidents, and injuries. Despite this, plenty of people continue to neglect their eye health. The World Health Organization (WHO) states that over 2.2 billion …

CREDIT: Carl Zeiss Vision International GmbH Myopia is becoming increasingly common, over 40% of the American population alone is affected by it, an increase of 15% since the 1970s. Myopia occurs when the eyeball is …
A preclinical study using stem cells to produce progenitor photoreceptor cells — light-detecting cells found in the eye — and then transplanting these into experimental models of damaged retinas has resulted in significant vision recovery. This finding, by scientists at Duke-NUS Medical School, the Singapore Eye Research Institute and the Karolinska Institute in Sweden, marks …
An international team of researchers led by Lithuanian scientists provides additional evidence that intracranial pressure plays an important role in normal-tension glaucoma, which accounts for up to 50 percent of all glaucoma cases. A recent clinical study demonstrates that low intracranial pressure correlates with impaired patient visibility, especially in the nasal zone. Glaucoma, one of …
NIH Highlights At A Glance: Replacing a component of a dietary supplement for treating age-related macular degeneration improved its safety and efficacy over a 10-year period. The results demonstrate the merits of the supplement formulation, called AREDS2. Age-related macular degeneration (AMD) is a degenerative disease of the eye that is the most common cause of …
A discovery about how some visually impaired adults could start to see offers a new vision of the brain’s possibilities. The finding that the adult brain has the potential to partially recover from inherited blindness comes from a collaboration between researchers at the University of California, Irvine School of Biological Sciences, and the School of …
The levels of long-term blood sugar, HbA1c, can be used to accurately determine the risk of a person with type 1 diabetes developing eye- and kidney complications. A study from Linköping University, Sweden, has shown that this level should be lower than 53 mmol/mol (7%). The study has followed individuals for more than 30 years …
The earlier individuals develop Type 2 diabetes or hypertension in life, the earlier they are likely to develop primary open-angle glaucoma (POAG), the leading cause of irreversible blindness worldwide, researchers from UT Southwestern reported in a recent study. The findings, published in Clinical Ophthalmology, could lead to better screening protocols for POAG, which accounts for …
Age-related eye diseases often lead to blindness and low vision in Americans. And the modern era of the screen is certainly not helping! However, if you are aware of common eye problems such as blurry vision, digital eye strain, amblyopia, etc., you can promptly start their treatment. Most eye problems, such as sudden blurry vision …
Loss of the protein pigment epithelium-derived factor (PEDF), which protects retinal support cells, may drive age-related changes in the retina, according to a new study in mice from the National Eye Institute (NEI). The retina is the light-sensitive tissue at the back of the eye, and aging-associated diseases of the retina, like age-related macular degeneration …
