摘要
Abstract
AIM: To investigate the sensibility of pattern visual evoked potential (P-VEP) on the diagnosis of glaucoma in different temporal frequency.METHODS: The P-VEP were recorded in 51 eyes of 30 primary glaucoma (PG) patients, 16 eyes of 13 ocular hypertension (OHT) patients and 46 eyes of 23 age-equivalent normal people using an array of different temporal frequency and then the patients were compared respectively with the normal group.RESULTS: The P100 wave amplitude in OHT group was significantly lowered at 8Hz, and was lowered at all temporal frequency in PG group, especially when the temporal frequency was higher.CONCLUSION: The P-VEP can be abnormal when the PG is still in its early stage, so it can be an index of early diagnosis and this is more obvious when the temporal frequency is higher, especially at 8Hz.关键词
