UASSIGNED:为了评估诊断精度并证明2台设备的等效性,先进的视觉分析仪(AVA,Elisar视觉技术)和汉弗莱现场分析仪(HFA,蔡司)在10-2程序上检测青光眼。
未经批准:预期,横截面,观察性研究。
UNASSIGNED:66例青光眼患者中每1只眼的阈值估计,36个控制参与者,10例青光眼疑似病例用AVA和HFA进行10-2试验分析。
UNASSIGNED:计算并比较了68个点和中心16个测试点的平均灵敏度(MS)值。类内相关性(ICC),布兰德-奥特曼(BA)地块,MS的线性回归,平均偏差(MD),计算和模式标准偏差(PSD)以评估设备的10-2阈值估计值。针对MS和MD值生成接收器工作特性曲线,曲线下面积(AUC)与评估诊断精度进行比较。
UNASSIGNED:68点和中心16点的平均灵敏度值,MS和MD值的AUC,ICC值,BA地块,和线性回归分析。
未经证实:Bland-Altman图显示MS的显著相关性,MD,和两个设备的PSD值。对于MS,总ICC值为0.96(P<0.001),平均偏倚为0.0dB,一致界限为7.59.两种设备之间的MS值差异为-0.4760±1.95(P>0.05)。AVA的MS值的AUC为0.89,HFA的AUC为0.92(P=0.188);而MD值在0.88相似(P=0.799)。先进的视力分析仪和HFA同样区分健康和青光眼患者(P<0.001),尽管HFA表示能力稍高(P>0.05)。
UNASSIGNED:统计结果表示AVA和HFA之间的等效性,因为AVA的阈值估计与10-2程序的HFA密切相关。

UNASSIGNED: To evaluate diagnostic precision and prove equivalence of 2 devices, Advanced vision analyzer (AVA, Elisar Vision Technology) and Humphrey field analyzer (HFA, Zeiss) for the detection of glaucoma on 10-2 program.
UNASSIGNED: Prospective, cross-sectional, observational study.
UNASSIGNED: Threshold estimates of 1 eye each of 66 patients with glaucoma, 36 control participants, and 10 glaucoma suspects were analyzed on 10-2 test with AVA and HFA.
UNASSIGNED: Mean sensitivity (MS) values of 68 points and central 16 test points were calculated and compared. Intraclass correlation (ICC), Bland-Altman (BA) plots, linear regression of MS, mean deviation (MD), and pattern standard deviation (PSD) were computed to assess the 10-2 threshold estimate of the devices. Receiver operating characteristic curves were generated for MS and MD values, and the area under the curve (AUC) was compared with assessing diagnostic precision.
UNASSIGNED: Mean sensitivity values of 68 points and central 16 points, AUC for MS and MD values, ICC values, BA plots, and linear-regression analysis.
UNASSIGNED: Bland-Altman plot showed significant correlation for MS, MD, and PSD values for both devices. For MS, the overall ICC value was 0.96 (P < 0.001) with a mean bias of 0.0 dB and limits of agreement range of 7.59. The difference in MS values between both devices was -0.4760 ± 1.95 (P > 0.05). The AUC for MS values for AVA was 0.89 and for HFA was 0.92 (P = 0.188); whereas it was similar at 0.88 for MD values (P = 0.799). Advanced vision analyzer and HFA identically discriminated between healthy and patients with glaucoma (P < 0.001), although HFA denoted marginally greater ability (P > 0.05).
UNASSIGNED: Statistical results denote adequate equivalence between AVA and HFA because threshold estimates of AVA strongly correlate with HFA for 10-2 program.
