Glaucoma Research Points To Potential Early Indicator
2013-01-02 13:21:05

Lee Rannals for redOrbit.com - Your Universe Online A new study has found that certain changes in blood vessels in the eye's retina can be an early sign that a person may have an increased risk of glaucoma. Researchers wrote in the journal Ophthalmology that they found that patients who have abnormally narrow retinal arteries are more likely to develop glaucoma 10 years down the road. The research could eventually provide ophthalmologists with a new tool to identify and treat those...

Study results show need for mandatory visual field testing for drivers The first study to compare accident rates for drivers who have advanced glaucoma – an eye disease that affects peripheral vision – with normal-vision drivers, found that the glaucoma group had about twice as many accidents. This study, which was conducted in Japan using a driving simulator, suggests that potential drivers should pass a visual field test to ensure adequate peripheral vision before a license...

Study in October's Ophthalmology journal may lead to preventive treatment for groups at risk for glaucoma People who take statins to reduce their risk of cardiovascular disease are less likely to be diagnosed with the most common form of glaucoma, according to a nationwide study of more than 300,000 patients. A University of Michigan School of Medicine research team, directed by Joshua Stein, MD, MS, found that the risk for glaucoma was reduced by eight percent in patients who took statins...

CLARKSBURG, Md., July 25, 2012 /PRNewswire/ -- The American Health Assistance Foundation (AHAF, http://www.ahaf.org), a nonprofit organization that funds breakthrough research on age-related vision diseases, announced today that it has awarded 21 new grants totaling $2.1 million to scientists worldwide who are studying glaucoma and macular degeneration. The two conditions are the leading causes of irreversible blindness in the world. "AHAF is known for pinpointing some of the world's most...

Findings in mice suggests hope for patients with glaucoma, optic nerve damage BOSTON, May 21, 2012 /PRNewswire-USNewswire/ -- Researchers have long tried to get the optic nerve to regenerate when injured, with some success, but no one has been able to demonstrate recovery of vision. A team at Boston Children's Hospital reports a three-pronged intervention that not only got optic nerve fibers to grow the full length of the visual pathway (from retina to the visual areas of the brain), but...

Two Blind Men Receive Some Sight Through Eye Implants
2012-05-04 05:05:10

Two blind men have received sight for the first time in years due to new advances in medical science. The Oxford Eye Hospital and King's College Hospital in London have been carrying out a clinical trial that helps restore sight to the blind, at least partially, through eye implants. Chris James and Robin Millar lost their vision due to a condition known as retinitis pigmentosa, which is when the photoreceptor cells at the back of the eye eventually cease to function. A 0.12-inch...

Women Have Bigger Pupils Than Men

From an anatomical point of view, a normal, non-pathological eye is known as an emmetropic eye, and has been studied very little until now in comparison with myopic and hypermetropic eyes. The results show that healthy emmetropic women have a wider pupil diameter than men. SINC Normal, non-pathological emmetropic eyes are the most common type amongst the population (43.2%), with a percentage that swings between 60.6% in children from three to eight years and 29% in those older than 66....

Working in mice, scientists at Washington University School of Medicine in St. Louis have devised a treatment that prevents the optic nerve injury that occurs in glaucoma, a neurodegenerative disease that is a leading cause of blindness. Researchers increased the resistance of optic nerve cells to damage by repeatedly exposing the mice to low levels of oxygen similar to those found at high altitudes. The stress of the intermittent low-oxygen environment induces a protective response called...

Jackson Laboratory researchers identify new damaging mechanism Jackson Laboratory researchers have demonstrated that a single, targeted x-ray treatment of an individual eye in young, glaucoma-prone mice provided that eye with apparently life-long and typically complete protection from glaucoma. In research published March 19 in the Journal of Clinical Investigation, Gareth Howell, Ph.D., Simon John, Ph.D., (professor and Howard Hughes Medical Investigator) and colleagues also used...
