MOTION COHERENCE PERIMETRY IN GLAUCOMA AND SUSPECTED GLAUCOMA

Motion direction sensitivity in glaucoma patients, glaucoma suspects a nd controls was assessed perimetrically at 22 visual field locations u sing small random dot kinematograms and a motion coherence task For fo veal stimulus presentations, mean motion coherence sensitivity was nor mal in both patient groups. However, nearly all glaucoma patients and about half of glaucoma suspects (all with normal visual fields as asse ssed with static perimetry) had some deficit of motion sensitivity. Th ese were most pronounced and most prevalent in the superior field at 1 5 and 21 deg eccentricity. Glaucoma appears to produce a reduction in the normal integrative visual function necessary for the perception of global motion in textured displays and this disruption is non-uniform ly distributed across the visual field.
