A review of the case histories of ten patients with optic tract lesions, an uncommon clinical entity, showed the primary characteristic to be a homonymous visual field defect that may be complete or incomplete. When the defect is incomplete, there is relative incongruity. When it is complete, there is an associated contralateral relative afferent pupillary defect. Visual acuity and color vision are preserved, unless there is bilateral involvement or anterior extension to involve the optic nerve or chiasm. When of sufficient duration, the contralateral fundus demonstrates band or "bow tie" atrophy of the disc and nerve fiber layer.
对10例视束病变患者（一种罕见的临床病症）的病历回顾显示，其主要特征是同向性视野缺损，可为完全性或不完全性。当缺损为不完全性时，存在相对不一致性。当缺损为完全性时，伴有对侧相对性传入性瞳孔障碍。视力和色觉得以保留，除非存在双侧受累或向前延伸累及视神经或视交叉。若病程足够长，对侧眼底可显示视盘和神经纤维层的带状或“领结样”萎缩。
