RESULTS: Of the 74 patients, 23 (31%) had ocular manifestations accompanied by other symptoms, including 3 (4.1%) with ocular syndrome accompanied with headache as the first symptoms of Moyamoya disease. Digital subtract angiography examination revealed 24 patients (32.4%) had unilateral or double stenosis of internal carotid artery, among which 3 patients had ocular syndrome. All positive eye findings included amaurosis fugax (13%), hemianopia (17%), decline or loss of the visual ability and lesions of visual fields (44%), papillary size dysfunction (13%), pupil direct/indirect light reflex (13%), ptosis (9%), nystagmus (4%), ocular dyscinesia (13%), and fossa orbitalis tenderness (9%).

结果：74例Moyamoya病患者中眼部症状与其它症状同时发生者23例（31%），其中仅以眼部症状伴头痛表现为首发症状就诊者3例（4%）；DSA检查显示单侧或双侧颈内动脉狭窄者24例（32%），其中3例患者双侧颈内动脉完全闭塞，而无任何眼部症状；23例患者所伴眼症表现主要为一过性黑朦13%，偏盲17%，视力下降甚至丧失44%，瞳孔大小异常13%，瞳孔直接/间接对光反射消失13%，上睑下垂9%，眼球震颤4%，眼球运动障碍13%，眼眶压痛9%。
