— The ability of the evoked potential to predict conventional visual acuity, as measured with a Landolt C test, was investigated for subjects with normal acuities. Both peak‐to‐trough and Fourier‐analysed amplitudes were used. The extrapolation technique assumed curvilinear regression and produced correlations no better than did a method employing amplitude measurements of a single check size of 5.5 min arc ( r = 0.67). Assessment of Landolt C acuity by subjective use of the evoked potential stimulus was unable to produce a higher correlation.
