正常人和青光眼计算机视野检查的可靠性研究

Reliability Study of Automatic Perimetry in Normals and Glaucoma

目的探讨计算机自动视野检查仪的可靠性指标在正常人和青光眼患者中的变化。方法采用Humphety—630型计算机视野检查仪对两组被检查者在受检过程中的三项可靠性指标（固视丢失率、假阳性率、假阴性率）进行监测比较。结果固视丢失率及假阴性率青光眼较正常人发生率有显著增高。结论固视丢失率及假阴性率的升高可在一定程度上反映青光眼视功能损害的情况。

Objective Resaarch the reiability changes of automatic perimetry in both normals and glaucoma patients.Methods Using Humphery-630 automatic field analyzer to detect the three reliability materia (fixation loss、false-positive rate、false-negative rate)in the two groups.Results The occurance rate was significantly higher in glaucoma than that in the normals.Conclus sion Increasing of fixation loss and false-negative rate could represent the visul functional disorder in glaucoma.
