Visual snow syndrome (VSS) is a neurological disorder characterized by persistent positive visual disturbances. VSS is known to be a rare condition; however, it is becoming increasingly recognized by neurologists and neuroophthalmologists. Despite this, it is not commonly described in pediatric patients.
We describe a pediatric girl with onset of persistent visual phenomena at age 13 years, which she described as "TV static," with associated afterimages, photopsia, nyctalopia, and photophobia. These visual disturbances have persisted for two years.
The patient's MRI revealed approximately 15 T2/fluid-attenuated inversion recovery hyperintensities in keeping with changes secondary to migraine. The ophthalmologic examination did not reveal an underlying cause. The patient's visual symptoms have been resistant to medications.
VSS is a recently described syndrome that is debilitating to patients. Further case descriptions, characterization of presentation, and management of patients with VSS, specifically in pediatric cases, are required.
视觉雪综合征（VSS）是一种以持续存在的阳性视觉障碍为特征的神经系统疾病。尽管 VSS 是一种罕见的病症，但神经科医生和神经眼科医生越来越多地认识到它。尽管如此，在儿科患者中并不常见。
我们描述了一名 13 岁女孩，她在 13 岁时开始出现持续的视觉现象，她将其描述为“电视静态”，伴有后像、闪光、夜视和畏光。这些视觉障碍已经持续了两年。
患者的 MRI 显示大约有 15 个 T2/液体衰减反转恢复高信号，与偏头痛引起的变化相符。眼科检查未发现潜在病因。患者的视觉症状对药物治疗有抵抗力。
VSS 是一种最近描述的综合征，对患者造成极大的困扰。需要进一步描述病例、描述表现特征，并对 VSS 患者进行管理，特别是儿科病例。
