摘要
本文报道正常组25例,周围病变组41例,中枢病变组25例的视动中枢试验.正常组各项试验均正常.周围病变组除3例视跟踪为Ⅱ型外,其余正常.中枢病变组视辨距试验异常10例,为40%:视限踪试验Ⅱ—Ⅳ型15例为60%:视动性眼震异常为80%.三组的视扫视试验,视跟踪试验和视动性眼震试验的结果有显著性差异(P<0.01),并统计三组其左右二向所诱发左右二向视动性眼震的频率、平均振幅和慢相速度之差值,差异有显著性(P<0.05)
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)
