Chiari I malformation presenting with ganglion cell complex thinning on routine examination

Abstract

Chiari I malformation (CMI) is a rare congenital disorder characterized by the caudal displacement of cerebellar tonsils through the foramen magnum into the cervical canal(1). Ophthalmological signs include retro-orbital pain, diplopia, photophobia, impaired visual acuity, nystagmus, strabismus, and papilledema(2-4). The diagnosis is mostly based on magnetic resonance imaging (MRI) findings © This content is licensed under a Creative Commons Attributions 4.0 International License.
