Selective Asymmetry of Ocular Vestibular-Evoked Myogenic Potential in Patients with Acute Utricular Macula Loss

Objectives We retrospectively evaluated a chart review of 3,525 patients for any acute disturbance. A total 1,504 with vestibular syndrome (AVS) received an instrumental assessment within 72 h from the onset symptoms using simultaneously combination ocular vestibular-evoked myogenic potential (oVEMPs), cervical (cVEMPs), video head-impulse test (vHIT), and subjective visual vertical (SVV) were included in this study. Materials methods 41 AVS that showed normal horizontal canal function tested vHIT, cVEMP function, unilaterally reduced or absent oVEMP n10, altered SVV enrolled. Results found although these referred vertigo presented spontaneous nystagmus, they physiological values vHIT saccular as shown by symmetrical cVEMPs. Conclusion Our findings support hypothesis percentage during could present selective utricular macula dysfunction.
