A 63-year-old male with a history of hypertension, hypercholesterolemia and chronic smoking, presented with a loss of the temporal visual field of right eye (RE). A restriction of the temporal field of RE and also of the nasal field of left eye was clinically suspected when the patient was tested by confrontation. A kinetic perimetry confirmed the existence of a right homonymous hemianopia that was very eccentric in both eyes (beyond the central 50 degrees). Brain magnetic resonance images revealed a well-circumscribed infarction in the ventral portion of the left calcarine fissure that was consistent with the patient's visual field loss.
Peripheral homonymous hemianopsia is a rare condition that is caused by a partial infarction of the most ventral striate cortex. Kinetic perimetry provided the most helpful information about the referred scotomas.
一名63岁男性,有高血压、高胆固醇血症病史且长期吸烟,出现右眼颞侧视野缺损。当通过对诊检查该患者时,临床怀疑右眼颞侧视野以及左眼鼻侧视野受限。动态视野计检查证实存在双眼非常偏心(超出中央50度)的右侧同向性偏盲。脑部磁共振成像显示左距状裂腹侧有一个边界清晰的梗死灶,与患者的视野缺损相符。
周边同向性偏盲是一种罕见的病症,由最腹侧纹状皮质的部分梗死引起。动态视野计检查提供了关于所提及暗点的最有用信息。
