摘　　要：动态等视线和静态光阈值测定都存在一定的波动性。不同时间检查,等视线位置和光阈值高低出现的离散称为长期波动。对于很多眼病,特别是青光眼的诊断、随访及其治疗效果的判断,定期复查视野是一必不可少的步骤。评价视野是否恶化或改善,首先应充分认识正常长期波动,否则就难以判断视野变化是属于正常波动。The knowledge of the long-term fluctuation,which affects thereproducibility of visual field meaurement is a prequisite for a quan-titative comparison of visual fields.Using the Goldmann perimeter,weconducted kinetic visual field measurements on two separate occasionsduring a ten-day period in 44 subjects with normal eyes(44eyes).Itsh-owed that the greatest variation appearing in the inferotemporal fieldand the isopter that was more peripheral.We put forward normal fl-uctuating value on I_2e and I_4e isopters,which are helpful to the esti-mation of deterioration or improvment of the visual field,and also,tothe early discovery of glaucomatous visual field damage.
