MedPage Today (10/26, Phend) reported that "when vision centers in the brain fall prey to an uncommon type of Alzheimer's disease, the early symptoms that stump a standard eye exam can be caught with a few simple tests," according to a study presented at an ophthalmology meeting. Researchers found that "one-sided defects on visual field testing were a giveaway in 80 percent of cases with the visual variant of Alzheimer's disease." MedPage added, "In the 10-patient case series they presented...a quick in-office assessment of higher cortical functioning was useful, as well."
