摘要: With regard to the use of slow conjugate eye movements in diagnosis ophthalmo-neurological disorders, suitability various stimulus parameters for routine examinations was evaluated and normative data were obtained with Infrared-Reflection-Oculography (IROG) from 21 healthy subjects. Sinusoidal smooth pursuit, additionally triangular stimuli used at frequencies visual as well vestibular stimulation a constant amplitude 30 degrees (± 15 deg). presentation proved be more adequate examining pursuit than triangular. For vestibulo-ocular reflex suppression (VORS) up 0.5 Hz appeared most suitable examinations. Normative also simple VORS test consisting manual back forth rotation subjects' head by examiner. Examinations (VOR) VOR (VVOR) are recommended particular clinical ...
