Johns Hopkins researchers report that chronic dry eye, a condition in which natural tears fail to adequately lubricate the eyes, can slow reading rate and significantly disrupt day to day tasks that require visual concentration for long periods of time.
Academic performance, interactions with peers, and athletic ability are factors connected to self-esteem in school children. This study of children in the third to eighth grades looked at whether the condition 'lazy eye' or amblyopia, where one eye has reduced vision due to misalignment or blur, was associated with lower self-perception by children of their competence, appearance, conduct and self-worth.
By combining two imaging modalities -- adaptive optics and angiography -- investigators at the National Eye Institute (NEI) can see live neurons, epithelial cells, and blood vessels deep in the eye's light-sensing retina. Resolving these tissues and cells in the outermost region of the retina in such unprecedented detail promises to transform the detection and treatment of diseases such as age-related macular degeneration (AMD), a leading cause of blindness among the elderly.
People who experience migraine with visual aura may have an increased risk of an irregular heartbeat called atrial fibrillation, according to a study published in the Nov. 14, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Cataracts surgery is a modern-day medical marvel, but even 10 years after a procedure, so-called secondary cataracts can form. UD researchers are identifying what's behind that and how to stop it.
The most common test for glaucoma can underestimate the severity of the condition by not detecting the presence of central vision loss, also known as macular degeneration, according to a new Columbia University study.
An enzyme known to help our liver get rid of ammonia also appears to be good at protecting our retina, scientists report.
Jayne Weiss, MD, Associate Dean of Clinical Affairs, Professor and Chair of Ophthalmology at LSU Health New Orleans School of Medicine, is the lead author of an editorial about inaccuracies in the medical literature that medical professionals rely upon to diagnose corneal dystrophies, as well as a free resource that provides correct information.
In an Acta Ophthalmologica analysis of 11 relevant articles, maternal smoking during pregnancy was associated with a 46 percent increased risk that offspring will develop strabismus -- one of the most prevalent eye-related diseases among children. Maternal smoking of 10 cigarettes per day during pregnancy was linked with a 79 percent increased risk of strabismus in offspring.
Summer birth and hours spent playing computer games are linked to a heightened risk of developing short or near sightedness (myopia) in childhood, indicates a twin study, published online in the British Journal of Ophthalmology.
