We report a 60-year-old woman with posterior cortical atrophy (PCA) who presented with left homonymous hemianopsia persisting for 5 years; the patient's condition was observed using static, but not kinetic, perimetry. This statokinetic dissociation of hemianopsia, which is often called Riddoch syndrome, might have been caused by a dysfunction of the right primary visual and visual association cortices, representing a functional imbalance within a disturbed visual cortex. In patients with PCA and visual field defects, both static and kinetic perimetry may be useful for understanding the extent of degeneration in the visual cortex, in addition to examinations of unilateral neglect.
我们报告了一名60岁患有后皮质萎缩（PCA）的女性，她出现左侧同向性偏盲并持续了5年；使用静态视野计而非动态视野计对该患者的病情进行了观察。这种偏盲的静态 - 动态分离现象，通常被称为里多克综合征，可能是由右侧初级视觉和视觉联合皮质功能障碍引起的，这代表了受干扰的视觉皮质内的功能失衡。对于患有PCA和视野缺损的患者，除了单侧忽视检查外，静态和动态视野计对于了解视觉皮质的退化程度可能都很有用。
