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 virus is known to cause microcephaly, in which infants are born with a smaller-than-normal head and brain. And previous research has found that one-third of Brazilian babies with microcephaly have eye problems such as ocular lesions, optic nerve abnormalities and chorioretinal atrophy, a withering of the retina and choroid. The choroid provides oxygen and nutrients to the retina. Now, this new report on three Brazilian infants with microcephaly identified three new eye problems: retinal lesions, bleeding in the retina and abnormal blood vessel development in the retina. The three infants also had the eye problems found in previous research. Since last spring, Brazil has been the epicenter of a Zika outbreak, and nearly 5,000 babies have been diagnosed with ...
