Ten patients with migraine developed persistent positive visual phenomena lasting months to years. The complaints were similar in their simplicity and involvement of the entire visual field and usually consisted of diffuse small particles such as TV static, snow, lines of ants, dots, and rain. Neurologic and ophthalmologic examinations were normal, and EEGs were normal in eight of eight patients tested. MRI was normal in all patients except one who had nonspecific biparietal white matter lesions and another with a small venous angioma. Treatment of this unusual complication of migraine was unsuccessful.
10名偏头痛患者出现了持续数月至数年的阳性视觉现象。这些症状在其简单性和累及整个视野方面相似，通常由弥漫性小颗粒组成，如电视静电干扰、雪花、蚁行线、小点和雨。神经学和眼科检查均正常，8名接受测试的患者脑电图也正常。除1例有非特异性双侧顶叶白质病变和另1例有小静脉血管瘤外，所有患者的MRI均正常。偏头痛这种不寻常并发症的治疗未成功。
