Abstract: System and Method pertaining to the modification and integration of an existing consumer digital camera, for example, with an optical imaging module to enable point and shoot fundus photography of the eye. The auto-focus macro capability of existing consumer cameras is adapted to photograph the retina over an extended diopter range, eliminating the need for manual diopter focus adjustment. The thru-the-lens (TTL) auto-exposure flash capability of existing consumer cameras is adapted to photograph the retina with automatic flash exposure eliminating the need for manual flash adjustment. The consumer camera imaging sensor and flash are modified to allow the camera sensor to perform both non-mydriatic focusing of the retina using infrared illumination and standard color flash photography of the retina without the need for additional imaging sensors or mechanical filters. These modifications and integration of existing consumer cameras for fundus photography of the eye significantly improve ease of manufacture and usability.

Abstract: Apparatus and techniques can include using one or more of a portable or fixed optical system to obtain images of a desired anatomical target, such as the fundus region of a human eye. The optical system can include one or more of a laser-based focusing target, a laser-based fixation target, or a removable or adjustable alignment assembly. Such an alignment assembly can provide or allow user alignment based on using anatomical landmarks other than the fundus being imaged. One or more of the apparatus or techniques can be implemented in an optical assembly included as a portion hand-held fundus camera, such as including or using a consumer or commercial digital camera to capture an image.
