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 over existing fundus cameras.

Various embodiments include systems and methods for ocular fundus examination reflection reduction. An illumination polarizer assembly can be configured to be user-attachable to an ophthalmological device and can be configured to position a first optical polarizer in an illumination portion of a light path associated with the ophthalmological device. An observation polarizer assembly can be configured to be user-attachable to the ophthalmological device and can also configured to position a second optical polarizer in an observation portion of the light path.

System and method directed towards providing full and even illumination of a patient's retina through lighting integrated into a handheld fundus lens. By integrating the lighting, the method and system reduces and even eliminate many lens artifacts and reflections. By increasing the accuracy, quality, and field of view afforded during clinical examination of the retina, the method and system will allow practitioners to make more accurate diagnoses and will increase safety during retinal surgical procedures.

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.
