一项对严重弱视人眼的定量心理物理和视网膜电生理[ERG]评估显示，当客观地收回时，没有心理物理缺陷的电生理视网膜类似物。除1例弱视患者外，其余弱视患者的ERG to模式和均匀视野闪烁均正常。在这个弱视中，虽然ERG缺陷与心理物理缺陷无关，但在均匀场刺激的二次谐波成分中也可以看到模式诱发反应的幅度降低。每种刺激措施的赤字只出现在高信号水平。正常眼和弱视眼对均匀场刺激的模式诱发反应和二次谐波反应的相似性表明了相似的潜在过程。
A quantitative psychophysical and electroretinographic [ERG] assessment of severely amblyopic human eyes revealed no electrophysiological retinal analogue of the psychophysical deficit, when objectively retracted. ERG to pattern and uniform field flicker were normal in all but one amblyope. In this amblyope, although the ERG deficit was uncorrelated with the psychophysical deficit, the reduced amplitude of the pattern-evoked response was also seen in the second harmonic component to uniform field stimulation. The deficit for each stimulus was only present at high signal levels. The similarity of the pattern evoked response and the second harmonic response to uniform field stimulation in normal and amblyopic eyes suggests a similar underlying process.
