Vision problems prompt older drivers to put down the keys
Date:1/6/2009

Rockville, MD With 30 million drivers in the US aged 65 and over, we count on older Americans to recognize when they can no longer drive safely and decide that it's time to stay off the road. A new study finds that a decrease in vision function is a key factor in bringing about this decision.

The Salisbury Eye Evaluation and Driving Study (SEEDS) (http://www.iovs.org/cgi/content/full/50/1/107), conducted by researchers affiliated with Johns Hopkins University, looked at changes in vision, cognition and the general health status of more than 1,200 licensed drivers aged 67-87 in Salisbury, MD, a community with limited public transportation. SEEDS is unique, in that the researchers performed comprehensive tests of both vision and cognitive function.

The results, recently published in the peer-reviewed journal Investigative Ophthalmology & Visual Science (www.iovs.org), reveal that after a year, 1.5 percent of the drivers had given up driving, and another 3.4 percent had restricted their driving. The most common predictors of stopping or decreasing driving were slow visual scanning, psychomotor speed and poor visuo-constructional skills, as well as reduced contrast sensitivity. (These skills are necessary to help drivers be aware of and respond to other cars, road conditions and road signs. Contrast sensitivity is the ability to detect detail in shades of gray; it is necessary for driving in poor weather and low lighting.)

"These skills are important for safe and confident driving where objects are moving at rapid speeds in relation to each other, and timely and accurate judgments are required," the researchers stated.

The study, which was in part supported by the National Institute of Aging, also found that women were four times more likely than men to stop or restrict their driving. In addition, drivers who had higher depressio
