Corticosteroid added to standard treatment improves eyesight in patients with sudden vision loss
Nonarteritic anterior ischemic optic neuropathy (NAION) is one of the leading causes of sudden and irreversible loss of vision in older adults. In a prospective randomized trial of 60 patients with NAION, investigators have shown that the addition of the corticosteroid fluocortolone to standard therapy significantly improves both short- and long-term visual acuity, especially when given soon after the onset of symptoms. Their results are published in Restorative Neurology and Neuroscience. (2013-11-19)

New device offers hope to people blinded due to incurable eye disorders
Research presented today at the 117th Annual Meeting of the American Academy of Ophthalmology shows promising data about a device that helps people who have lost their vision due to a blinding genetic disease to recognize common objects. In the study, the researchers found when the objects' outlines had been enhanced, there was increased recognition. The device, called the Argus II, is the first FDA-approved retinal implant for adults with retinitis pigmentosa. (2013-11-16)

Congenital blindness results in lower thermal pain thresholds
An international team of scientists investigated whether congenitally blind subjects experience pain differently than sighted individuals. Their results, published in the current issue of PAIN®, reveal compelling evidence that congenitally blind individuals are hypersensitive to pain caused by thermal stimuli. (2013-11-01)

Alarming increasing incidence of myopia
New research on myopia -- how it develops, risk and protective factors, and potentially effective measures for prevention and treatment are reported across twenty articles in the Nov. issue of Optometry and Vision Science, official journal of the American Academy of Optometry.

All the better to see you with: Snakes alter blood flow dynamics to aid vision
Much like a pair of closed eyelids a snake's eye is covered layer of skin riddled with tiny blood vessels. Although this layer is transparent Kevin van Doorn for the University of Waterloo, Canada, wondered if the blood vessels caused problems with vision. Delving deeper, van Doorn finds that during periods when clear vision may be advantageous snakes decrease the amount of time the vessels staying dilated, keeping the eye as blood-free as possible.

Contact lens discomfort: What is it, why does it occur and how can it be treated?
Contact lens discomfort may be the leading cause of patient dissatisfaction with, and discontinuation of, contact lens wear throughout the world -- but there is little agreement among vision researchers and eye care professionals about how to define and manage its causes. The Tear Film and Ocular Surface Society organized the TFOS International Workshop on Contact Lens Discomfort and findings were reported Friday in the current issue of journal Investigative Ophthalmology and Visual Science.

(2013-09-13)

The eyes have it
Methylmercury compounds specifically target the central nervous system, and among the many effects of their exposure are visual disturbances, which were previously thought to be solely due to methylmercury-induced damage to the brain visual cortex. However, after combining powerful synchrotron X-rays and methylmercury-poisoned zebrafish larvae, scientists have found that methylmercury may also directly affect vision by accumulating in the retinal photoreceptors, i.e., the cells that respond to light in our eyes. (2013-09-11)

Look at what I'm saying
University of Utah bioengineers discovered our understanding of language may depend more heavily on vision than previously thought: under the right conditions, what you see can override what you hear. (2013-09-04)

Study shows that people who undergo cataract surgery to correct visual impairment live longer
People with cataract-related vision loss who have had cataract surgery to improve their sight are living longer than those with visual impairment who chose not to have the procedure, according to an Australian cohort study published this month in Ophthalmology, the journal of the American Academy of Ophthalmology. After comparing the two groups, the researchers found a 40 percent lower long-term mortality risk in those who had the surgery. (2013-09-04)

Coming soon to an optometrist's office near you: Wavefront analysis
Techniques developed by astronomers seeking a clear view of objects in space are coming closer to home, as eye care professionals apply the concept of wavefront optics to understanding -- and correcting -- subtle visual abnormalities of the human eye, according to a special article in the September issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. (2013-08-27)

Language can reveal the invisible, study shows
It is natural to imagine that the sense of sight takes in the world as it is -- simply passing on what the eyes collect from light reflected by the objects around us. But the eyes do not work alone. What we see is a function not only of incoming visual information, but also how that information is interpreted in light of other visual experiences, and may even be influenced by language. (2013-08-26)

UCI, UCLA study reveals new approach to remedying childhood visual disorders
By discovering the role of key neurons that mediate an important part of vision development, UC Irvine and UCLA neurobiologists have revealed a new approach to correcting visual disorders in children who suffer from early cataracts or amblyopia, also known as lazy eye. (2013-08-26)

Research breakthrough: Impaired autophagy associated with age-related macular degeneration
A new study published in the prestigious PLoS One journal changes our understanding of the pathogenesis of age-related macular degeneration (AMD). The researchers found that degenerative changes and loss of vision are caused by impaired function of the lysosomal clean-up mechanism, or autophagy, in the fundus of the eye. The results open new avenues for the treatment of the dry form of AMD, which currently lacks an efficient treatment. (2013-08-21)

Therapeutic eye injections may be needed less often
Biomedical engineers have created a new drug-delivery strategy for a type of central vision loss caused by blood vessel growth at the back of the eye, where such growth should not occur. The team gave the drug a biodegradable coating to keep it in the eye longer. If effective in humans, monthly needle sticks to the eye, which are the current standard of care, could be replaced with only two or three injections per year. (2013-08-19)

Human eye movements for vision are remarkably adaptable
When something gets in the way of our ability to see, we quickly pick up a new way to look according to a new study. Our eyes are constantly on the move, darting this way and that. Now researchers have found that the precise manner of those eye movements can change within a matter of hours. This discovery might suggest a way to help those with macular degeneration better cope with vision loss. (2013-08-15)
