Eye exams are constantly being improved upon, the latest involving "a test developed using mice that can help measure two important aspects of retinal health--the function of retinal blood vessels and light-detecting cells," writes Science Daily. By creating a 2-in-1 eye exam, researchers hope to make such trips to the optometrist much more thorough and efficient.
Bruce Berkowitz, Ph.D., a researcher involved in the work from the Department of Anatomy/Cell Biology/Ophthalmology at Wayne State University School of Medicine, says, "We believe these findings will enhance and speed decisions about treatment in patients with specific diseases of the eye." Using a new form of magnetic resonance imaging, researchers took two pictures of the retina, one in the dark and one in the light. By comparing the two, they found that earlier detection of problems is possible.
