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.
Both high and low HDL levels are linked to age-related macular degeneration risk
University of California San Diego researchers have identified a U-shaped association between high-density lipoprotein (HDL) levels and age-related macular degeneration (AMD) risk, with lower incidence of AMD in the middle range and peaks in both the lower and upper ranges. The team also discovered specific genetic variants related to HDL metabolism as contributing factors to AMD.
Treatment to preserve sight in children with rare genetic disorder shows promise in clinical trial
A new treatment that could prevent blindness in children with the CLN2 type Batten disease has been trialed by clinicians and researchers at UCL and Great Ormond Street Hospital (GOSH).
Empagliflozin linked to reduced progression of diabetic retinopathy
An investigation led by Brigham and Women's Hospital finds empagliflozin (sold as Jardiance) may reduce the risk of diabetic retinopathy (DR) progression in patients with a history of nonproliferative diabetic retinopathy (NPDR) but showed no association with preventing new NPDR onset.
Sleep apnea associated with age-related macular degeneration
A Center for Eye Research Australia study has linked low levels of oxygen in the blood overnight—a common sign of obstructive sleep apnea—with wet age-related macular degeneration.
