What is astigmatism? Why does it make my vision blurry? And how did I get it?

Have you ever gone to the optometrist for an eye test and were told your eye was shaped like a football?

Impact of sociodemographic factors, treatment compliance, age of diagnosis in amblyopia treatment outcomes

Amblyopia, commonly referred to as "lazy eye," is the leading cause of vision loss in one eye in children, affecting around 2% of the population. Treatment success varies based on sociodemographic factors, with previous studies ...

Eye scan can reveal risk of having a heart attack or stroke

A simple digital photograph of the back of the eye can predict a major cardiovascular event—such as a heart attack or stroke—set to happen in the next decade with 70% accuracy, according to research supported by the British ...

Scientists target mitochondrial dysfunction in children's eye disease

Autosomal dominant optic atrophy (ADOA), the most common genetic optic neuropathy, is an insidious disease. It often presents slowly during childhood by way of blurry vision, trouble reading or focusing, and sometimes only ...

Cancer drug shows promise as treatment for blindness

Singapore researchers have discovered that a new cancer drug, originally developed at A*STAR Institute of Molecular and Cell Biology (A*STAR IMCB), shows potential as a new treatment approach for two leading causes of blindness ...

NRTI use linked to risk for primary open-angle glaucoma

Use of nucleoside and nucleotide reverse transcriptase inhibitors (NRTIs) is associated with an increased risk for primary open-angle glaucoma (POAG), according to a study published online June 20 in Ophthalmology.

Neuroscience

Babies' poor vision may help organize visual brain pathways

Incoming information from the retina is channeled into two pathways in the brain's visual system: one that's responsible for processing color and fine spatial detail, and another that's involved in spatial localization and ...

Video: Visual snow, a rare disorder

Winter means snow starts falling in many parts of the country. But there's a different kind of snow that appears year-round for some people across the globe.

New potential mechanism for vision loss discovered

Visual cells in the human retina may not simply die in some diseases, but are mechanically transported out of the retina beforehand. Scientists from the Deutsches Zentrum für Neurodegenerative Erkrankungen (DZNE) and the ...

New genetic mutation behind childhood glaucoma identified

An international team of scientists led by Mass Eye and Ear, a member of Mass General Brigham, and Boston Children's Hospital, has discovered a new genetic mutation that may be a root cause of severe cases of childhood glaucoma, ...

Ganglion cells created in mice in bid to fix diseased eyes

While fish, reptiles and even some birds can regenerate damaged brain, eye and spinal cord cells, mammals cannot. For the first time, non-neuronal cells have been induced to mimic specific ganglion cells in the eyes of mice.

Neuroscience

Could we train our brains to see new colors?

For birders struggling to differentiate between male and female blue tits, the answer lies here. The crest of the male actually appears as ultraviolet (UV) to other tits, a distinction invisible to us humans.

New study shows repeated stress accelerates aging of the eye

New research from the University of California, Irvine, suggests aging is an important component of retinal ganglion cell death in glaucoma, and that novel pathways can be targeted when designing new treatments for glaucoma ...

Neuroscience

Understanding the minutiae of seeing in 3D

So much has to go right as our visual systems develop. One of them is that many thousands of retinal ganglion cells (RGCs) have to relay signals through the eye's optic nerve via delicate projections, or axons, to precise ...

Aging eyesight issues and treatment

Diminishing eyesight is a common issue that occurs with age. While often unavoidable, routine eye checks are crucial.

A new device for early diagnosis of degenerative eye disorders

Researchers at an EPFL lab have developed an ophthalmological device that can be used to diagnose some degenerative eye disorders long before the onset of the first symptoms. In early clinical trials, the prototype was shown ...
