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 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
