Optometrists can help to prevent falls by avoiding over-aggressive vision correction in older patients at risk, according to the review by David B. Elliott, PhD, 2013 recipient of the prestigious Glenn A. Fry Lecture Award. "Our 2013 Glenn A. Fry Award winner has been studying the effects of blurred vision and vision correction on falls among the elderly," comments Anthony Adams, OD, PhD, Editor-in-Chief of Optometry and Vision Science.
"In his Award-winning lecture, he provides some very special insights into how this may happen and how we as a profession may help to minimize falls related to vision loss."
Vision correction may actually increase risk of falling
Falls are the major cause of accidental death and nonfatal injuries in elderly US adults. At least one-third of healthy adults aged 65 or older fall at least once a year. For those aged 90 or older, the risk increases to about 60 percent.
But falls in older adults aren't accidents, according to Dr. Elliott. Most of the time, they're related to a wide range of risk factors including older age, disabilities, muscle weakness, and many different medical conditions. "The more risk factors you have, the more likely you are to fall," Dr. Elliott writes.
Reduced vision is one important risk factor, suggesting that interventions to correct vision -- particularly glasses and cataract surgery -- would reduce the risk of falling. Surprisingly, however, most studies have shown little or no reduction in falls among older adults receiving a new vision correction.
Magnification from some new glasses provided in one study may contribute to the increase in risk, Dr. Elliott suggests. "Some of the subjects received large changes in spectacle prescription. Older frail people may have greater difficulty adapting to such changes and be at increased risk of falling during this adaptation period."
