ABSTRACT:
An ophthalmic augmented reality environment is developed in order to allow for (a) more precise laser treatment for ophthalmic diseases, (b) teaching, (c) telemedicine, and (d) real-time image measurement, analysis, and comparison. A preferred embodiment of the system is designed around a standard slit-lamp biomicroscope. The microscope is interfaced to a CCD camera, and the image is sent to a video capture board. A single computer workstation coordinates image capture, registration, and display. The captured image is registered with previously stored, montaged photographic and/or angiographic data, with superposition facilitated by fundus-landmark-based fast registration algorithms. The computer then drives a high intensity, VGA resolution video display with adjustable brightness and contrast attached to one of the oculars of the slit-lamp biomicroscope.
