Motion direction sensitivity in glaucoma patients, glaucoma suspects and controls was assessed perimetrically at 22 visual field locations using small random dot kinematograms and a motion coherence task. For foveal stimulus presentations, mean motion coherence sensitivity was normal in both patient groups. However, nearly all glaucoma patients and about half of glaucoma suspects (all with normal visual fields as assessed with static perimetry) had some deficit of motion sensitivity. These were most pronounced and most prevalent in the superior field at 15 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-uniformly distributed across the visual field.
使用小随机点运动图和运动连贯性任务，在22个视野位置通过视野计对青光眼患者、青光眼疑似患者和对照组的运动方向敏感性进行了评估。对于中央凹刺激呈现，两组患者的平均运动连贯性敏感性均正常。然而，几乎所有青光眼患者和约一半的青光眼疑似患者（所有患者经静态视野检查评估视野均正常）都存在一定程度的运动敏感性缺陷。这些缺陷在视野上方15度和21度偏心度处最为明显且最为普遍。青光眼似乎会导致在有纹理显示中感知全局运动所需的正常综合视觉功能下降，并且这种破坏在视野中分布不均匀。
