    Measurement of the glaucomatous cup using sequentially acquired stereoscopic images
    (ELSEVIER SCI LTD, 2003) Guesalaga, A; Irarrazabal, P; Guarini, M; Alvarez, R
    This paper describes a new method for recovering the three-dimensional surface of the optic disc based on stereoscopic techniques. The images that form the stereo pair are obtained sequentially from standard ophthalmoscopes. The method is based on calibration algorithms for an optical set-up and uses a novel algorithm for the search of correspondences in the stereo pair that is unique for this kind of applications. It is proposed as a quantitative tool in the diagnosis of the primary open angle glaucoma. The technique shows a robust performance, is simple to embed in an clinical ophthalmoscope, and is a low-cost solution to diagnose and control the glaucoma pathology. (C) 2003 Elsevier Ltd.
