Correlation between the spectral-domain optical coherence tomography (SD-OCT) line scans and multifocal electroretinography (mfERG) of a patient with birdshot chorioretinopathy (a–d). The area through which the line scan passes is shown in the infrared image in a. The OCT line scan (d) shows disruption of the inner and outer retinal layers at an area temporal to the foveal center. The mfERG trace arrays show abnormal waveforms at the retinotopically correlated points represented by the area of tissue disruption on OCT (b). In addition, the numeric values below the abnormal waveforms show reduced amplitude density at these areas of interest. The hexagons in (c) (2D topography maps) depict the implicit times at each of the tested areas. In the area of SD-OCT retinal layer disruption, there are increased implicit times noted in red. The color map also shows blunted mfERG response (e)
