In two patients, a 60-year-old woman and a 63-year-old man, cerebral blindness was diagnosed. The first patient developed the disorder shortly after cerebral angiography was carried out to diagnose a carotid-cavernous fistula. The symptoms disappeared after three days. The second patient suffered from a reversible posterior leuko-encephalopathy syndrome. He recovered his vision without specific treatment. Cortical or cerebral blindness is a form of blindness caused by a lesion in the cerebral part of the visual pathways. Although in itself rare, cerebral blindness occurs frequently as a complication of non-neurologic diseases or interventions. Physicians who are unaware of this syndrome tend to diagnose these patients as 'hysteric', since normal pupillary reactions and normal eye movements accompany the loss of vision. If the blindness is not caused by an ischaemic infarct, it is usually reversible.
在两名患者中，一名60岁女性和一名63岁男性被诊断为皮质盲。第一名患者在进行脑血管造影以诊断颈动脉海绵窦瘘后不久出现该病症。症状在三天后消失。第二名患者患有可逆性后部白质脑病综合征。他未经特殊治疗视力就恢复了。皮质盲或大脑性失明是由视觉通路脑部病变引起的一种失明形式。虽然其本身罕见，但皮质盲常作为非神经系统疾病或干预的并发症出现。不了解这种综合征的医生往往将这些患者诊断为“癔症性”，因为视力丧失的同时瞳孔反应和眼球运动正常。如果失明不是由缺血性梗死引起，通常是可逆的。
