Real-time tracking and overlay of previously stored photographic and angiographic images directly onto the real- time slitlamp biomicroscopic or surgical microscopic eye fundus image may facilitate real-time image comparison, measurement, and correlation for diagnosis, management and treatment of retinal diseases. Very high resolution and brightness is necessary to inject the overlayed image into the optical path of the diagnostic or surgical instrument. A binocular slit-lamp biomicroscope interfaced to a CCD camera, framegrabber board, and PC allows for posterior segment examination with a hand-held contact or non-contact lens, synchronous with acquisition and digitization of slitlamp fundus images.
