METHOD AND APPARATUS FOR EXAMINING AND PHOTOGRAPHING THE OCULAR FUNDUS ABSTRACT OF THE DISCLOSURE An instrument for photographing the ocular fundus is aligned by using a physical aperture designed to permit il- lumination of only a small area of the optic disc for minimal patient awareness of incident light and corresponding pupil dilation without mydriatics. The increased field of view and obliquity of viewing afforded by pupil dilation permits flushing of the fundus for photographic recording without image obscuring corneal reflections. The light restricting aperture is removed immediately before photographic recording.
