When Diabetes Strikes, Get Moving to Lower Risk to Eyes

Posted 4 Aug 2016 by Drugs.com

THURSDAY, Aug. 4, 2016 – People with diabetes who remain inactive may have higher odds for a vision-robbing eye condition, new research suggests. While the study couldn't prove a cause-and-effect relationship, researchers say a "couch potato" lifestyle does seem to raise the risk for diabetic retinopathy. According to the U.S. National Eye Institute, the condition "involves changes to retinal blood vessels that can cause them to bleed or leak fluid, distorting vision." Diabetic retinopathy is the most common cause of vision loss for people with diabetes. Could exercise – or a lack of it – affect risk for the disease? To find out, a team led by Paul Loprinzi at the University of Mississippi tracked outcomes for 282 U.S. diabetes patients. The patients averaged 62 years of age. Nearly one-third (29 percent) had mild or more severe diabetic retinopathy. Using an accelerometer device to ... Read more

Routine Eye Exams See Vision Problems You Miss

Posted 14 Jul 2016 by Drugs.com

WEDNESDAY, July 13, 2016 – Routine eye checkups often pick up unnoticed problems, particularly in older adults, a new study says. "In asymptomatic patients, comprehensive routine optometric eye examinations detect a significant number of new eye conditions and/or results in management changes," said the study's author, Elizabeth Irving, and her colleagues from the University of Waterloo in Ontario, Canada. More than half of people with no new symptoms or vision problems receive new prescriptions or treatment changes as a result of routine eye exams, the researchers found. The need for vision prescription changes was found for two out of five people, the study noted. Meanwhile, 16 percent were diagnosed with a new eye condition and 31 percent had a change in their ongoing care, researchers found. The study included data on nearly 6,400 patients who visited a university eye clinic over ... Read more

Nearly 10 Million Americans Are Severely Nearsighted

Posted 21 Jun 2016 by Drugs.com

TUESDAY, June 21, 2016 – About 9.6 million Americans are severely nearsighted, a new study finds. Rates of nearsightedness – also known as myopia – in the United States rose from 25 percent in the early 1970s to 40 percent around 2000, the study authors said. Most cases of nearsightedness can be corrected with eyewear or surgery. However, severe nearsightedness can cause complications that threaten vision. The new study is based on federal data, plus an analysis of an American Academy of Ophthalmology database. The researchers estimate that nearly 820,000 Americans have a degenerative form of myopia called progressive high myopia, which can cause weakening of the retina. More than 40,000 of these individuals may also develop an even more serious condition called myopic choroidal neovascularization. This is "a severe complication of myopia with abnormal fragile blood vessels growing ... Read more
