To investigate the risk factors and prognosis for ischemic third, fourth, and sixth cranial nerve palsies in a Korean population. ⋯ Ischemic ocular motor cranial nerve palsy is closely related to diabetes mellitus, hypertension, and hyperlipidemia in Korean patients. Compared with the fourth or sixth nerve palsy groups, the third nerve palsy group showed a tendency to have multiple risk factors. Recovery takes longer when 2 or more risk factors were present or when abnormal findings were observed on neuroimaging.

Concussion, particularly in relation to sports and combat activities, is increasingly recognized as a potential cause of both short- and long-term neurologic sequelae. This review will focus on the neuro-ophthalmologic findings associated with concussion, the current tests for concussion, and the potential for visual performance measures to improve our detection and assessment of concussions. ⋯ Concusssion is associated with many neuro-ophthalmologic signs and symptoms. Visual performance measures enhance the detection and management of concussion, and future studies are under way to further incorporate vision-based testing into sideline diagnosis and long-term clinical assessments.

A 39-year-old woman with a history of Behçet disease presented for evaluation of oscillopsia that began postpartum. Examination showed oculopalatal tremor (OPT), documented videographically. Brain magnetic resonance imaging revealed bilateral pseudohypertrophy of the inferior olivary nuclei. Treatment with gabapentin was initiated for OPT presumed secondary to neuro-Behçet disease.

Dr. Airy's "morbid affection of the eyesight": lessons from Teichopsia Circa 1870.
Hubert Airy's iconic drawing of his own migraine visual aura for which he coined the term, "teichopsia," conveys important lessons for the contemporary clinician. His observations of the expansion ("build-up"), minification/magnification, and color/achromatopsia of migrainous teichopsia are consistent with (and possibly anticipatory of) the later discoveries of cortical spreading depression, cortical magnification of primary visual cortex (V1), and specialized cortical centers for color vision.
