INTRODUCTION Visual snow (VS) is a rare condition that is characterized by continuous dynamically flickering dots in the entire visual field that imitate the 'static' or 'snow' of an analogue television set that is not connected to the antenna (1). VS was first described in 3 of 10 migraineurs patients who presented with a spectrum of positive visual symptoms (2). The symptoms of VS can persist for many years. Although VS might be expressed in patients with migraine as visual aura, persistent VS has been accepted as a distinct clinical entity and termed as visual snow syndrome (VSS) independently from migraine. Schankin et al. proposed that the criteria for diagnosis of VSS consisted of visual snow as the main criterion, with some additional criteria (3). A few cases with childhood VSS have been described in literature (4-6). Herein, the case of a teenager was presented to emphasize the importance of differential diagnosis in persistent positive visual phenomena.
简介
视觉雪（VS）是一种罕见的病症，其特征是整个视野中连续出现动态闪烁的点，类似于未连接天线的模拟电视机的“静态”或“雪花”（1）。VS 最初是在 10 名偏头痛患者中的 3 名患者中描述的，他们表现出一系列阳性视觉症状（2）。VS 的症状可能会持续多年。尽管 VS 可能在偏头痛患者中表现为视觉先兆，但持续的 VS 已被认为是一种独立于偏头痛的明确临床实体，并被命名为视觉雪综合征（VSS）。Schankin 等人提出，VSS 的诊断标准包括将视觉雪作为主要标准，还有一些其他标准（3）。文献中已经描述了一些儿童 VSS 的病例（4-6）。在此，我们报告了一名青少年患者的病例，以强调在持续性阳性视觉现象中进行鉴别诊断的重要性。
