Abnormal spectral sensitivity of the electroretinographic off-response in protanopia and protanomalia

Abstract

The mean of the spectral sensitivity of the rapid off-response in the ERG is significantly lower at 560 nm and longer wavelengths (p < 0.005) in protanopia and protanomalia, as compared with normal control subjects.
