Large sample population age norms for visual acuities obtained with Vistech-Teller Acuity Cards.

Abstract

The binocular and monocular grating VA norms obtained in this large-sample study are different from the preliminary norms published with the TAC. Results from this and other studies (see Mayer et al, page 671, this issue) strongly point to a need for redefinition of the preliminary VA norms.
