A visual field defect is the most important neurologic defect in occipital lobe infarcts. There are only sporadic case reports of altitudinal hemianopia in the published data. We report a patient with bilateral superior altitudinal hemianopia.
A 40-year-old man developed bilateral superior altitudinal hemianopia secondary to bilateral parahippocampal and fusiform gyrus lesions. Vision loss was acute, and onset bilateral and simultaneous. Complete neuro-ophthalmologic examinations were performed. His best corrected visual acuity was 20/20 in each eye. Macula and retina examinations were normal. Visual fields were characterized by bilateral upper hemianopia. Cerebral magnetic resonance imaging (MRI) confirmed the presence of symmetrical lesions confined within both bilateral parahippocampal and fusiform gyri. Blood tests, transesophageal echocardiographic examination, and Doppler ultrasonography of the vertebrobasilar arterial system and carotids were normal.
We conclude that embolic events may induce a bilateral superior altitudinal hemianopia.
视野缺损是枕叶梗死中最重要的神经功能缺损。在已发表的数据中，仅有散在的双侧性上象限盲病例报告。我们报告一例双侧性上象限盲患者。
一名40岁男性因双侧海马旁回和梭状回病变继发双侧性上象限盲。视力丧失急性起病，双侧同时发生。进行了全面的神经眼科检查。他每只眼睛的最佳矫正视力均为20/20。黄斑和视网膜检查正常。视野检查表现为双侧上象限盲。脑部磁共振成像（MRI）证实双侧海马旁回和梭状回内存在对称性病变。血液检查、经食管超声心动图检查以及椎基底动脉系统和颈动脉的多普勒超声检查均正常。
我们得出结论，栓塞事件可能诱发双侧性上象限盲。
