A 32-year-old woman with benign concentric annular macular dystrophy (BCAMD) was examined with multifocal electroretinography (mfERG) and microperimetry. The mfERG demonstrated reduced focal responses in the area corresponding to the scotoma shown by microperimetry. The correspondence between mfERG and microperimetry in a patient with BCAMD shows that inner retinal layers, which include photoreceptors, are affected and these changes lead to visual field defects.
