BACKGROUND
Migraine is a common neurological disorder affecting children, in which the headache is often preceded or accompanied by a complex of neurological symptoms known as an aura. Persistent visual symptoms are rare, with typical visual aura sometimes being poorly distinguished from other visual disturbances.
METHODS
We describe the case of a 12-year-old girl who has experienced persistent, constant symptoms throughout the visual fields of white, bright, jagged spots and black and white flashes with sparkles and dots since May 2010. She also has palinopsia, squiggles, and photophobia. The child's drawing of her visual symptoms helps illustrate the case and illuminate her ordeal.
RESULTS
The child's visual symptoms have so far been resistant to pharmacological therapy.
CONCLUSION
Further insight is needed into this debilitating condition to allow effective management in the pediatric population.
背景
偏头痛是一种常见的儿童神经系统疾病，头痛常伴有或先于一种称为先兆的复杂神经系统症状。持续性视觉症状较为罕见，典型的视觉先兆有时与其他视觉障碍难以区分。
方法
我们描述了一例 12 岁女孩的病例，自 2010 年 5 月以来，她的整个视野一直持续出现白色、明亮、锯齿状斑点和黑白闪烁、带有火花和斑点的症状。她还伴有视觉后像、扭曲和畏光。孩子对其视觉症状的描绘有助于说明该病例并阐明她的痛苦。
结果
目前，该患儿的视觉症状对药物治疗有抗性。
结论
需要进一步深入了解这种使人虚弱的疾病，以便在儿科人群中进行有效的管理。
