Groundbreaking research from the University of Houston shows that a single low-dose atropine eye drop can produce daylong effects in managing myopia, or nearsightedness, which affects roughly one-third of U.S. adults. Professor of Optometry Lisa Ostrin and postdoctoral researcher Barsha Lal are reporting that even one drop in the eye of low-dose atropine (0.01%–0.1%) produces clear changes in pupil size and focusing ability that persist for at least 24 hours. Importantly, they also found that the drop shows no short-term structural effects on the eye, with only temporary changes in blood flow inside the retina.
