Neurotological Findings in a Patient with Glufosinate Ammonium Intoxication: Ji Young Kim, Joo Yeon Ham, Seong-Hae Jeong; Res Vestib Sci. 2020;19(4):138-140. Published online December 15, 2020; DOI: https://doi.org/10.21790/rvs.2020.19.4.138

Abstract PDF Supplementary Material: The upward deviation could be explained by loss of inhibitory inputs from the cerebellum onto the brainstem anterior semicircular canal projections for upward vestibulo-ocular reflex, which would lead to an upward bias in static eye position. Therefore, upward gaze deviation has been reported in comatose patients after resuscitation and diffuse cerebrocerebellar damage sparing the brainstem. Herein, we report a patient with ingestion of glufosinate ammonium presented with cerebellar ataxia and ocular motor findings suggestive of cerebellum involvement such as upward gaze tendency, spontaneous downbeat, gaze-evoked nystagmus, perverted head impulse test, and impaired smooth pursuit.
