Abstract:
To investigate the changes of vedionystamography(VNG)in patients with posterior circulation ischemia vertigo(PCIV).Fifty patients who complained of vertigo and imbalance with PCI were selected as experimental group for testing of visual nystamography(VNG).Thirty normal subjects were chosen as control group.The result was analyzed.The results of VNG in PCIV group and the control group were compared.The abnormal ratio were as follows:(4%,0;>0.05)for Spontaneous nystagmus,(68%,10%;<0.01)for Saccade Test,(42.0%,6.7%;<0.01)for Tracking Test,(44%,0;<0.01)for Optokinetic Test,(78%,10%;<0.01)for Positional Test,respectively.The intensity of positional nystagmus in those patients was(4.12±3.46)°/s,which was much higher than that of the control group(<0.01).One or more abnormal findings for visual-oculomotor system examination were shown in 37 patients(74%).Both vestibular central and peripheral system can be involved in PCIV.VNG test has clinical significance in differential diagnosis and lesion location.The abnormal ratio of visual nystamography in PCIV group reaches 92%(46/50).These results suggest that VNG be used as an important accessory diagnostic tool for patients with PCIV.
