Optic nerve ultrasonography in the evaluation of the relationship between arachnoid cyst and headache.

Aim: This study is aimed to show the difference between optic nerve sheath diameter (ONSD) values in migraine patients with and without arachnoid cysts from migraine patients and control groups, and to evaluate the relationship with the arachnoid cyst size on magnetic resonance imaging (MRI) and their clinical severity.

Methods: This cross-sectional study included pediatric patients who were previously diagnosed with migraine and the control group. The patients consist of 3 groups.
