Glaucoma patients at significantly higher risk for falls, motor vehicle accidents

02.03.2007
Likelihood higher than reported in previous studies

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.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
