    Cellular imaging of the living human retina
    A device combining optical coherence tomography and adaptive optics can capture micron-scale 3D pictures of the retina. Viewing the retina through the eye's cornea and crystalline lens dates back to the time of Helmholtz, inventor of the ophthalmoscope. Ophthalmoscopes have advanced substantially since then and are now an indispensable non-invasive tool for diagnosis and treatment monitoring. While there are three principal types—conventional ophthalmoscopes, confocal scanning laser ophthalmoscopes (cSLOs), and optical coherence tomography (OCT)).123 The latter has changed the diagnosis and monitoring of retinal and optic nerve disease most.
