Abstract

PURPOSE

To compare the diagnostic accuracy of the pattern electroretinogram (pattern ERG) to that of standard automated perimetry (SAP), short-wavelength automated perimetry (SWAP), and frequency-doubling technology (FDT) perimetry for discriminating between healthy and glaucomatous eyes.

DESIGN

Cross-sectional study.

METHODS

Eighty-three eyes of 42 healthy recruits and 92 eyes of 54 glaucoma patients (based on optic disc appearance) from the University of California, San Diego, Diagnostic Innovations in Glaucoma Study were tested with pattern ERG for glaucoma detection (PERGLA; Lace Elettronica, Pisa, Italy), SAP, SWAP, and FDT within 9 months. Receiver operating characteristic (ROC) curves were generated and compared for pattern ERG amplitude and SAP, SWAP, and FDT mean deviation and pattern standard deviation (PSD). Sensitivities and specificities were compared and agreement among tests was described.

RESULTS

The area under the ROC curve for pattern ERG amplitude was 0.744 (95% confidence interval = 0.670, 0.818). The ROC curve area was 0.786 (0.720, 0.853) for SAP PSD, 0.732 (0.659, 0.806) for SWAP PSD, and 0.818 (0.758, 0.879) for FDT PSD. At 95% specificity, sensitivities of SAP and FDT PSD were significantly higher than that of pattern ERG amplitude; at 80% specificity, similar sensitivities were observed among tests. Agreement among tests was slight to moderate.

CONCLUSION

The diagnostic accuracy of the pattern ERG amplitude was similar to that of SAP and SWAP, but somewhat worse than that of FDT. Nevertheless, the pattern ERG may hold some advantage over psychophysical testing because of its largely objective nature.

摘要

目的

比较图形视网膜电图(图形 ERG)与标准自动视野计(SAP)、短波长自动视野计(SWAP)和频域倍增技术(FDT)在鉴别健康眼与青光眼眼中的诊断准确性。

设计

横断面研究。

方法

对来自加利福尼亚大学圣地亚哥分校诊断性青光眼创新研究的 42 名健康应征者的 83 只眼和 54 名青光眼患者(根据视盘外观)进行图形 ERG 检查以进行青光眼检测(PERGLA;意大利比萨 Lace Elettronica),在 9 个月内进行 SAP、SWAP 和 FDT 检查。生成并比较了图形 ERG 振幅和 SAP、SWAP 和 FDT 平均偏差及图形标准偏差(PSD)的接收器工作特性(ROC)曲线。比较了敏感性和特异性,并描述了测试之间的一致性。

结果

图形 ERG 振幅的 ROC 曲线下面积为 0.744(95%置信区间=0.670,0.818)。SAP PSD 的 ROC 曲线下面积为 0.786(0.720,0.853),SWAP PSD 为 0.732(0.659,0.806),FDT PSD 为 0.818(0.758,0.879)。在 95%特异性下,SAP 和 FDT PSD 的敏感性显著高于图形 ERG 振幅;在 80%特异性下,各测试之间的敏感性相似。测试之间的一致性为轻度至中度。

结论

图形 ERG 振幅的诊断准确性与 SAP 和 SWAP 相似,但略逊于 FDT。尽管如此,由于其主要的客观性,图形 ERG 可能比心理物理测试具有一定的优势。
