Abstract
Abstract A method of self-examining the interior of the ocular globe by applying a light source to the outer surface of the lower eyelid, with the eye closed in order to permit the entrance of the light from said light source only through the thickness of said lower eyelid and without said light passing through the crystalline or other focusing element of the eye, whereby the inner structure of the eye is rendered visible to the patient. An apparatus for carrying out the method includes a light source housed in a casing having a transparent smooth cover adapted to be contacted under a slight pressure with the exterior surface of the lower eyelid, and a power source for the light source.
