ABSTRACT:
A system for performing an examination of the eye of a subject which uses a source of light and a concave mirror for focusing such light at a selected region of the fundus of the eye so as to form an enlarged optical image of the selected region at a selected spatial region which is remote from the eye. An ophthalmoscope, or camera, or other viewing instrument is then focused at the selected spatial region to permit the selected region of the eye to be viewed either immediately or photographed for subsequent viewing.
