Eye Movements Induced by Stimulation to the Otolith Organs

Background: We have been performing a canalith repositioning procedure for benign paroxysmal positional vertigo. When we adopted the Epley maneuver posterior semicircular canal type, and affected-ear-up 90° lateral noticed that no nystagmus occurred in sitting position just after treatment. Despite direct excitation to utricle by pathological debris, none of subjects complained dizziness. Thus, hypothesized dizziness do not occur stimulation otolith organs. Objective: The aim study was observe record eye movements induced organs confirm our hypothesis. Materials Methods: Twelve healthy humans were tested. In position, head tilted right ear 45° vice versa. Afterward, bent forward (nose-down), subject’s seat reclined head-hanging position. Each kept five seconds. interviewed assess their Results: None showed every Conclusions: Nystagmus does organs; therefore, ocular counter-rolling is reflex.
