    Sightseeing: Adaptive optics could peer deep into damaged eyes for earlier diagnoses
    The earlier diabetic retinopathy, macular degeneration and glaucoma—the three most prevalent diseases causing blindness—can be diagnosed, the more successfully they can be treated. Obtaining high-res images of the retina is not so easy, however, due to aberrations caused by imperfections in the cornea and crystalline lens. Using the same adaptive optics principles that let astronomers see distant objects with such instruments as the Keck Telescope, researchers have created a new device for ophthalmologists to see the eye's retina at the individual cell level. Researchers at Lawrence Livermore National Lab (LLNL), the Indiana University School of Optometry, Boston ...
