ABSTRACT:
An image acquisition unit provides true color high resolution digital images of the retina of the eye to a computer network (14, 16, 18) which interfaces with a central record library and displays the images at a remote work station (20A and 20B) for diagnostic examination. The computer network (14, 16, 18) is also interfaced with a unit for entering medical history information, and the diagnostic data, stereo images and medical records are linked in a relational database allowing all text and image records of the patient to reside on a work station/display (20A and 20B) for review or consultation. A telecommunications link (22) interconnects the computer network and image examination stations with the image acquisition station where the patient is actually examined, so that stereo fundus images may be made available through the computer without degradation for viewing on the examination displays remotely from the room, building, or city where the images are acquired from the patient. By introducing digital true-color normalization at the image acquisition source (34,32), applicant avoids the problem of spurious color artifacts arising when the images are viewed subsequently, or on other monitors.
