Persons affected by glaucoma are over three times more likely to have been involved in falls and motor vehicle accidents than persons of the same age without the condition, say researchers from Dalhousie University in Canada. Their findings are published in the March 2007 issue of Investigative Ophthalmology & Visual Science.
The study involved 48 patients 50 years of age or older with glaucoma and 47 age-matched persons without the eye disease. Glaucoma patients were almost three times as likely to have experienced one or more falls in the previous year and over six times as likely to have been involved in one or more motor vehicle accidents in the previous five years. They were also more likely to have been at-fault for motor vehicle accidents in which they were involved. The strongest risk factor for these motor vehicle accidents was impaired useful field of view.
This research shows higher levels of falls and motor vehicle accidents than found in previous studies. These results have a potential useful application in patient education, licensing of drivers, and intervention programs.
"Based on these results, the research group has started a larger prospective study to better understand why patients with glaucoma may be more likely to have falls and motor vehicle accidents," said researcher Sharon A. Haymes, PhD, of the Department of Ophthalmology and Visual Sciences at Dalhousie University. "We need to find ways to help them minimize their risk."
Glaucoma is a group of diseases of the optic nerve involving loss of retinal ganglion cells in a characteristic pattern of optic neuropathy. If left untreated, glaucoma can lead to permanent damage of the optic nerve and resultant visual field loss, which can progress to blindness. It is the second leading cause of blindness worldwide and affects 1 in 200 people aged 50 and younger and 1 in 10 over the age of 80.
There are currently no known ways to prevent glaucoma. However, studies show that early detection and treatment of the disease, before it causes major vision loss, is the best way to control the disease. The National Eye Institute recommends that persons who are at high risk for the disease (African-Americans over 40; persons over 60; and people with a family history of glaucoma) have their eyes examined and pupils dilated every two years by an eye care professional.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
