The Status of Vernier Acuity Following Late Sight Onset.

ABSTRACT: We possess a remarkably acute ability to detect even small misalignments between extended line segments. This "vernier acuity" significantly exceeds our "resolution acuity"-the ability to resolve closely separated stimuli-and is generally considered a "hyperacuity," since the detectable misalignments are markedly finer than the diameter of single retinal cones. Vernier acuity has, thus, often been proposed to reflect spatial organization and multi-unit cortical processing, rendering it an important index of visual function. Notably, vernier acuity exhibits a characteristic developmental signature: it is inferior to resolution acuity early in life but eventually exceeds it by up to one order of magnitude. However, vernier acuity may be disproportionately sensitive to developmental disruptio
