  • Title: Medial medullary infarction: abnormal ocular motor findings.
    Author: Kim JS, Choi KD, Oh SY, Park SH, Han MK, Yoon BW, Roh JK.
    Journal: Neurology; 2005 Oct 25; 65(8):1294-8. PubMed ID: 16247061.
    Abstract:
    In 20 consecutive patients with isolated medial medullary infarction, abnormal ocular motor findings included nystagmus (n = 8), ocular contrapulsion (n = 5), and contralesional ocular tilt reaction (n = 2). The nystagmus was ipsilesional (n = 4), gaze-evoked (n = 5), upbeating (n = 4), and hemiseesaw (n = 1). The ocular motor abnormalities may be explained by involvements of the nucleus prepositus hypoglossi, medial longitudinal fasciculus or efferent fibers from the vestibular nuclei, climbing fibers, and cells of the paramedian tracts.
