单侧青光眼视野缺损患者假阴性反应的眼间差异

目的 探讨单侧青光眼视野缺损患者电脑视野检查假阴性反应率的眼间差异及相关因素。方法 选取2000年1月～2002年10月在青岛大学医学院附属医院眼科视野检查室行Octopus101自动静态视野检查的单侧青光眼视野缺损患者66例进行研究；比较患者眼间视力、眼压、杯盘比、检查时间及假阴性反应率、假阳性反应率、平均偏差、平均光敏感度的差异，并分析假阴性反应率的相关因素。结果 视野缺损眼与视野正常眼的假阴性反应率(FN)差异显著，且与检查的先后顺序无关，而两眼在视力、眼压、瞳孔直径等方面无明显差异；视野缺损眼平均偏差(MD)与FN相关，在MD越高的眼，FN越高；而正常眼MD与FN无关。结论 假阴性反应率可能与视野缺损有关；用假阴性反应率作为可靠性指数来监测受检者的专心程度、注意力集中程度，是不合适的。

Intereye differences of false-negative response in patients with unilateral glaucomatous visual field defect

ObjectiveTo determine the intereye differences of false negative-responses rate(FN) and mean deviation(MD) in glaucoma patients with unilateral visual field defect.MethodsSixty-six glaucoma patients with damaged visual field in one eye and normal fellow eye received automated perimetry(Octopus 101 perimeter) during Jan,2000 and Oct,2002 at affiliated hospital of medical college of Qingdao University.Intereye differences of false-negative responses rate(FN)and MD of visual field,acuity,IOP,test duration,c/d ratio and their relationship were analyzed.ResultsFN was significantly different between damaged eyes and normal eyes(P<0.01) without obvious correlation with testing sequence.No significant intereye differences were found in visual acuity,IOP and pupil diameter(P>0.05).FN was related to MD in damaged eyes(r=0.74,P=0.003),while no significant relationship between FN and MD was found in normal eyes(r=0.05,P=0.79).ConclusionFN reflects only visual field state of glaucoma patients in some extent,so it is infeasible to take it as a predict index to evaluate the attentiveness of patients.
