Onset of Visual Snow Syndrome After the First Migraine Episode in a Pediatric Patient: A Case Report and Review of Literature.

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.
