Eye health linked to dementia risk
Dunedin Multidisciplinary Health and Development Study researchers discovered the blood vessels at the back of the eye-called retinal microvasculature-can show early signs someone is at risk of developing dementia.
New insights into eye drainage cells' response to forces could inform glaucoma treatments
A new study on glaucoma, a leading cause of irreversible blindness, offers a fresh understanding of how the disease progresses and points the way toward new treatments. The study, published today in Matter, examined the behavior of cells in the eye's drainage system.
Treating dry eye disease may reduce migraine severity
Adults with dry eye disease and migraine who were treated with eye drops for ocular lubrication experienced significant reductions in migraine severity, according to a study published in Optometry and Vision Science.
How to protect your eyes in the digital age: Expert in eye and vision science
In an era where screens dominate our daily lives, a silent epidemic is sweeping the globe. Digital eye strain, a condition once relegated to the fringes of occupational health concerns, has emerged as a significant public health issue affecting millions worldwide.
Early treatment may still be needed for eyes with stable myopic normal-tension glaucoma
Overall, 22.5% of patients with myopic normal-tension glaucoma showed progression requiring treatment. Those with a family history of glaucoma or higher IOP were at an especially increased risk for progression.
Demodex collarettes associated with itching, fluctuating vision
Collarettes are a pathognomonic sign of Demodex blepharitis and are significantly correlated with symptoms such as itching, fluctuating vision, irritation and redness, according to a study.
Genetic risk for glaucoma increases with age
An international collaborative research effort found that with aging, a higher genetic risk score is a stronger predictor of elevated intraocular pressure (IOP) and an increased chance of developing
Novel stem cell therapy repairs 'irreversible' corneal damage in clinical trial
An expanded clinical trial that tested an experimental stem cell treatment for blinding cornea injuries found the treatment was feasible and safe in 14 patients who were treated and followed for 18 months, and there was a high proportion of complete or partial success.
Myopia is a disease, not a refractive error. Here's what that means
Myopia is a refractive error (blurred vision at a given distance) that affects about 30% of the world's population. This proportion is increasing so quickly that it is estimated it will reach 50% by 2050. The United States-based National Academy of Sciences (NAS) recently changed the way myopia is defined. NAS now considers myopia to be a disease rather than a refractive error.
Research shows just one hour of screen time increases risk of nearsightedness
Each hour a person spends squinting into a smartphone or staring at a screen increases their risk of nearsightedness, a new evidence review suggests.
