    • n ophthalmoscope An instrument for viewing the interior of the eye, especially for examining the retina. In the simplest form of the instrument light is condensed into the eye by means of a concave mirror, through a small hole in the center of which the observer examines the eye. Behind the body are attached a disk containing sixteen lenses and a quadrant containing four lenses, so arranged that any lens of the disk (either singly or in combination with any lens of the quadrant) can be brought into position behind the central hole in the mirror for determining the focus of vision.
    • ophthalmoscope To view the eye by means of the ophthalmoscope.
