In experiments on rats outfitted with tiny goggles, scientists say they have learned that the brain’s initial vision processing center not only relays visual stimuli, but also can “learn” time intervals and create specifically timed expectations of fut…

Light exposure during pregnancy key to normal eye development
New research concludes the eye — which depends on light to see — also needs light to develop normally during pregnancy. Scientists say the unexpected finding offers a new basic understanding of fetal eye development and ocular diseases caused by vasc…
Scientists discover genes responsible for cornea blindness
Scientists have succeeded in identifying genes for central corneal thickness that may cause potentially blinding eye conditions. These eye conditions include glaucoma, as well as the progressive thinning of the cornea, which may eventually lead to a ne…
3-D movies linked to increased vision symptoms
Watching 3D movies can “immerse” you in the experience -— but can also lead to visual symptoms and even motion sickness, reports a new article.
How does nearsightedness develop in children?
Myopia (nearsightedness) develops in children when the lens stops compensating for continued growth of the eye, according to a new study.
Outside temperatures, sun exposure and gender may trigger glaucoma
When it comes to whether or not you will develop exfoliation syndrome — an eye condition that is a leading cause of secondary open-angle glaucoma and increased risk of cataract as well as cataract surgery complications — age, gender and where you liv…
Aging eyes linked to sleepless nights, new study shows
A natural yellowing of the eye lens that absorbs blue light has been linked to sleep disorders in a group of test volunteers. The connection could help explain why sleep disorders become more frequent with increasing age.
Scientists discover new role for vitamin C in the eye and the brain
Nerve cells in the eye require vitamin C in order to function properly — a surprising discovery that may mean vitamin C is required elsewhere in the brain for its proper functioning, according to a new study.
How omega 3s help to prevent several forms of blindness
New research reveals exactly how omega-3 fatty acids work in preventing several forms of blindness.
Advanced macular degeneration is associated with an increased risk of bleeding stroke, study finds
In the first study to examine stroke subtypes in age-related macular degeneration (AMD), older people with late-stage AMD appear to be at increased risk of bleeding stroke, but not a stroke caused by a blood clot in the brain. However the findings are …
Why do some diabetics escape complications?
Much research has been carried out on why diabetics develop complications. Now researchers are asking the question the other way around. They want to know why some diabetic patients do not develop complications. What is it that protects them? The PROLO…
Melanopsin looks on the bright side of life
Better known as the light sensor that sets the body’s biological clock, melanopsin also plays an important role in vision: Via its messengers-so-called melanopsin-expressing retinal ganglion cells, or mRGCs-it forwards information about the brightness …
New evidence for eye-protective effects of omega-3-rich fish, shellfish
Researchers wanted to know how the risk of age-related macular degeneration (AMD) would be affected in a population of older people who regularly ate fish and seafood, since some varieties are good sources of omega-3 fatty acids. A diet rich in omega-3…
Eye movement problems common cause of reading difficulties in stroke patients
Eye movement problems that result in difficulty reading are as common as vision loss in stroke patients, researchers at the University of Liverpool have found.
Photos of tiny blood vessels in the eye link air pollution to heart disease
By digitally photographing the tiny, hair-like blood vessels in the back of our eyes, researchers can now look directly at how small blood vessels like those that bring blood to the heart respond to air pollution.
International clinical trial tests targeted drug for melanoma
Rush University Medical Center has just enrolled the first US patient in an international clinical trial testing a novel drug to treat certain kinds of melanoma, a deadly skin cancer that in its advanced stages currently has few effective treatments.
Novel genetic mutation that causes the most common form of eye cancer discovered
A new study has revealed the discovery of a novel oncogene that is associated with uveal melanoma, the most common form of eye cancer.
Laser system shows promise for cataract surgery
A new system for femtosecond laser-assisted cataract surgery is not only safe but also cuts circles in lens capsules that are 12 times more precise than those achieved by the traditional method, as well as leaving edges that are twice…
Artificial retina more capable of restoring normal vision; animal study shows including retina’s neural ‘code’ improved prosthetic
Researchers have developed an artificial retina that has the capacity to reproduce normal vision in mice. While other prosthetic strategies mainly increase the number of electrodes in an eye to capture more information, this study concentrated on incor…
Young, unsupervised children most at risk for dog bites, study shows; Dogs often target a child’s face and eyes
As dog bites become an increasingly major public health concern, a new study shows that unsupervised children are most at risk for bites, that the culprits are usually family pets and if they bite once, they will bite again with the second attack often…
