Unformatted text preview: Vision Science III – Ocular motility and binocular vision Lab 2 Feedback 3/27/06 In Lab 2, we measured the horopter using the AFPP technique. What is a horopter ? • Set of points in space that stimulate corresponding points on the two retinas and which have zero binocular disparity . The horopter helps us understand how the binocular system has been designed to allow for sensory fusion of the images seen by the two eyes. In theory, the horopter ought to be the same as the Vieth-Müller Circle ( VMC ). What’s the Vieth-Müller Circle? It is the theoretical horopter based on the assumptions that the … • eyes are circular in horizontal cross section; • nasal-temporal symmetry of oculocentric visual directions; • OD-OS symmetry. Empirical horopters usually don’t match the VMC. None of the ones we measured did. -5.0 0.0 5.0 10 15 20 25-15-10-5.0 0.0 5.0 10 15 AFPP (NM) OFPP Disparity relative to VMC (arc min) Eccentricity (deg) VMC-5.0 0.0 5.0 10 15 20 25 30-15-10-5.0 0.00....
