Vision correction in older adults may actually increase the risk of falling rather than decrease it, according to an article in the June Optometry and Vision Science. Unaccustomed magnification in new glasses may make objects appear closer or farther than they are in reality, which in turn affects the reflex system linking balance with eye movements. Additionally, a switch to bifocals or progressive lenses in patients who aren’t used to such modalities may lead to distorted peripheral vision.

For the second time in one week, Valeant Pharmaceuticals increased its bid to acquire Allergan. On May 28, Valeant officials offered Allergan $58.30 per share––roughly equivalent to $49.5 billion––after a previous bid rejection at $48.30 per share in April.

There may be a link between taking vasodilators and developing early AMD, according to a study recently published in Ophthalmology. Researchers from University of Wisconsin School of Medicine and Public Health conducted a long-term, population-based study of nearly 5,000 patients from 1988 to 2013. After adjusting for age and sex, the investigators found that using a vasodilator was associated with a 72% greater risk of developing early-stage AMD. Of the subjects who did not take vasodilators, approximately 8.2% developed early-stage AMD; approximately 19.1% of those using vasodilators developed the disease.
