| definition |
Partial or complete loss of vision in one half of the visual field(s) of one or both eyes. Subtypes include altitudinal hemianopsia, characterized by a visual defect above or below the horizontal meridian of the visual field. Homonymous hemianopsia refers to a visual defect that affects both eyes equally, and occurs either to the left or right of the midline of the visual field. Binasal hemianopsia consists of loss of vision in the nasal hemifields of both eyes. Bitemporal hemianopsia is the bilateral loss of vision in the temporal fields. Quadrantanopsia refers to loss of vision in one quarter of the visual field in one or both eyes. 偏盲，指一侧或双侧眼睛正常视野中一半的缺失。如果双眼的视野缺失为同侧，但每侧眼睛视野的缺损小于一半，损伤也许位于枕叶，否则有可能是顶叶及颞叶的损伤。偏盲是由可影响视交叉、视束或视辐射的损害所引起。某些眼科疾病也可引起偏盲型视野缺损，如晚期青光眼的鼻侧视野缺损，视网膜血管阻塞时的偏盲型视野缺损，视网膜部分脱离时相对方向的视野缺损等。治疗应查找引起偏盲的原发疾病，针对病因治疗。 Hemianopsia, or hemianopia, is a loss of vision or blindness in half the visual field, usually on one side of the vertical midline. The most common causes of this damage are stroke, brain tumor, and trauma. A heteronymous hemianopsia is the loss of half of the visual field on different sides in both eyes. |
