Sudden, transient loss of vision in one eye (amaurosis fugax) is associated frequently with atherosclerosis of the internal carotid artery in adults and may herald a stroke. Thus, cerebral angiography is often performed. Amaurosis fugax in children is uncommon and an underlying cause is rarely demonstrated. Recurrent episodes of amaurosis fugax occurred in five adolescents. A characteristic evolution and pattern of visual loss, consistent with choroidal ischemia as the underlying mechanism, was described by four of them. Although none of the episodes were accompanied by headache, four patients had a history of common migraine at other times or a family history of migraine. These episodes of visual loss may represent a migraine variant, and cerebral angiography is not indicated in adolescents with such a history.
单眼突发短暂性视力丧失（一过性黑矇）在成人中常与颈内动脉粥样硬化相关，可能是中风的先兆。因此，常需进行脑血管造影。儿童一过性黑矇并不常见，且很少能找出潜在病因。五名青少年反复出现一过性黑矇发作。其中四人描述了与脉络膜缺血为潜在机制相符的特征性视力丧失演变及模式。尽管发作时均无头痛，但四名患者曾有过普通偏头痛病史或有偏头痛家族史。这些视力丧失发作可能代表一种偏头痛变异型，对于有此类病史的青少年，无需进行脑血管造影。
