This paper reports oculomotor central tests on 25 normal subjects

41 cases of peripharal’diseases.and 25 cases of centra) diseasses.All tets were normal in normal subjects.The tests were normal in peripheral diseases except that three cases of eye tracking test were type Ⅲ.Ocular saccade was abnormal in 10 cases (40%)

eye tracking test was typeⅢ-IV in 15 cases (60%)

and abnormality of optokinetic nystagmus was 80% in central diseases.A marked difference was found in ocular saccade

eye tracking and optokinetic nystagmus tests among three groups(P<0.01). We found that differenoes of frtquncy

equal amplitude of vibration and nystagmus slow phase velocity of the eye to the right and left in optokinetic nystagmus of three groups had significant difference (P<0.05)
