一位71岁的男性经历了急性发作的困难，阅读字母在右视野。他的既往病史包括高血压和糖尿病。全身检查无异常。在神经系统检查中，不存在麻痹、感觉障碍和共济失调。目前的病史启发我们右同侧偏盲，随后的Humphrey视野检查确实显示了右旁中央同侧偏盲暗点（图1A），这通常是由枕极病变引起的。然而，脑部MRI显示视放射源急性梗死，与左脉络膜前动脉（AChA）区域一致（图1B）。实验室数据显示血脂和凝血酶原时间正常。HbA1c为7.4%。
A 71-year-old man experienced an acute onset of difficulty in reading letters in the right visual field. His past medical history included hypertension and diabetes mellitus. The general examination was unremarkable. On neurological examination, paralysis, sensory disturbance and ataxia were not present. History of present illness inspired us right homonymous hemianopsia, and subsequent Humphrey visual field test indeed revealed right paracentral homonymous hemianopic scotoma (Figure 1A), which is typically caused by a lesion in the occipital pole. Brain MRI, however, showed acute infarction in the origin of the optic radiation, consistent with left anterior choroidal artery (AChA) territory (Figure 1B). Laboratory data revealed a normal lipid profile and prothrombin time. HbA1c was 7.4%.
