The influence of age on optokinetic nystagmus (OKN) was studied in 63 healthy subjects, who were divided into three groups according to their age, group I ( 20-39 years), II ( 40-59 years) and III ( 60-82 years) It was found that on average maximal OKN velocity decreases considerably with age, from
Horizontal and vertical OKN and OKAN were recorded in four conditions using the EOG technique. Instructions to subjects were aimed at obtaining a "look" type OKN. Two optokinetic stimulators, a stationary sphere and a binocular portable model, were compared with the subject in the upright condition.
