研究了内斜视患者眼球运动在运动深度知觉中的作用。在斜视中已经显示了升高的运动视差阈值[Thompson，A. M.，& Nawrot，M.（1999年）。弱视者运动视差引起的深度知觉异常。Vision Research，39，1407 - 1413]，这表明涉及立体视觉和运动的深度知觉的整体缺陷。然而，斜视中的这种运动视差缺陷可能更好地解释为眼睛运动在运动视差中的作用[Nawrot，M.，& Joyce，L.（2006年）。运动视差的追踪理论。Vision Research，46，4709 - 4725]。内斜视与不对称追踪和视动反应眼球运动有关[Demer，J.L.，& von Noorden，G. K.（1988年）。内斜视的视动不对称。Journal of Pediatric Ophthalmology and Strabismus，25，286 - 292; Schor，C. M.，& Levi，D.

The role of eye movements in the perception of depth from motion was investigated in esotropia. Elevated motion parallax thresholds have been shown in strabismus [Thompson, A. M., & Nawrot, M. (1999). Abnormal depth perception from motion parallax in amblyopic observers. Vision Research, 39, 1407–1413] suggesting a global deficit in depth perception involving both stereopsis and motion. However, this motion parallax deficit in strabismus might be better explained by the role that eye movements play in motion parallax [Nawrot, M., & Joyce, L. (2006). The pursuit theory of motion parallax. Vision Research, 46, 4709–4725]. Esotropia is associated with asymmetric pursuit and optokinetic response eye movements [Demer, J. L., & von Noorden, G. K. (1988). Optokinetic asymmetry in esotropia. Journal of Pediatric Ophthalmology and Strabismus, 25, 286–292; Schor, C. M., & Levi, D. M. (1980). Disturbances of small-field horizontal and vertical optokinetic nystagmus in amblyopia. Investigative Ophthalmology and Visual Science, 19, 851–864; Tychsen, L., & Lisberger, S. G. (1986). Maldevelopment of visual motion processing in humans who had strabismus with onset in infancy. The Journal of Neuroscience, 6, 2495–2508; [Westall, C. A., Eizenman, M., Kraft, S. P., Panton, C. M., Chatterjee, S., & Sigesmund, D. (1998). Cortical binocularity and monocular optokinetic asymmetry in early-onset esotropia. Investigative Ophthalmology and Visual Science, 39, 1352–1360.]. The first experiment demonstrates that the motion parallax deficit in esotropia mirrors the pursuit eye movement asymmetry: in the direction of normal pursuit, esotropic observers had normal depth from motion parallax. A second set of experiments, conducted in normal observers, demonstrates that this motion parallax deficit is not a secondary problem due to the retinal slip created by inadequate pursuit. These results underscore the role of pursuit eye movements in the perception of depth from motion parallax.
