Abstract： 目的探讨蓝黄视野及黄斑阈值视野检测在早期原发性青光眼诊断中的应用价值. 方法采用Humphrey Ⅱ-750型自动视野计,对正常人60例60只眼、早期原发性青光眼患者63例63只眼进行标准视野(white-on-white perimetry, W/W)、蓝黄视野(blue-on-yellow perimetry, B/Y)及黄斑阈值视野(macular threshold perimetry, MTP)检查,计算比较3种检测方法在早期原发性青光眼诊断中的敏感度及特异度,并采用B/Y及MTP并联及串联实验进行分析. 结果比较正常组与早期原发性青光眼组W/W、B/Y、MTP的平均光敏感度,差异均有显著性的意义[t=-3.01, P=0.005 4 (W/W);t=-2.95, P=0.006 3 (B/Y);t=-2.59,P=0.015 0 (MTP)].在早期原发性青光眼诊断中,MTP的敏感度最高(83%),B/Y次之(65%),W/W最低(48%).将B/Y与MTP联合运用时,并联试验可使敏感度提高到94%;串联试验可使特异度提高到87%. 结论在早期原发性青光眼诊断中,B/Y、 MTP及两者的联合应用均可提高诊断的敏感度与特异度,有一定的应用价值.
