Introduction

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.

Methods

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.

Results

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.

Conclusion

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.

儿科患者首次偏头痛发作后视觉雪综合征的发作：病例报告和文献回顾

介绍

视觉雪综合征 (VSS) 是一种以持续性积极视觉障碍为特征的神经系统疾病。众所周知，VSS 是一种罕见的疾病。然而，它越来越受到神经科医生和神经眼科医生的认可。尽管如此，它在儿科患者中并不常见。

方法

我们描述了一名在 13 岁时出现持续性视觉现象的儿科女孩，她将其描述为“电视静态”，并伴有相关的残像、幻觉、夜盲症和畏光症。这些视觉障碍已经持续了两年。

结果

患者的 MRI 显示大约 15 个 T2/流体衰减反转恢复高信号，与继发于偏头痛的变化保持一致。眼科检查未发现根本原因。患者的视觉症状已对药物产生抗药性。

结论

VSS 是最近描述的一种使患者衰弱的综合征。需要进一步的病例描述、表现特征和 VSS 患者的管理，特别是在儿科病例中。
