38 Migraine SyndromeAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyThe image shows a patient with cluster headache and eye displaying Horner's syndrome.
39 Neuro-Ophthalmic Imaging-MRIAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyAxial view of Arnold-Chiari malformation on a patient with downbeat nystagmus. Note the presence of the cerebellar tonsils posterior to the caudal medulla. In addition to downbeat nystagmus, Arnold-Chiari malformations can sometimes lead to increased intracranial pressure and papilledema.
