Correlation Between Visual Acuity and Foveal Threshold With Size V Stimulus

Automated perimetry is invaluable for assessment of visual fields, and additionally the foveal threshold measured by automated perimetry can be valuable given its known correlation with visual acuity (1, 2). Although the size V stimulus has been demonstrated to be more reproducible in certain clinical scenarios (3, 4), there is currently a paucity of data regarding the correlation of foveal threshold to visual acuity when utilizing the size V stimulus. We aimed to characterize the correlation between foveal threshold as determined by automated perimetry with a size V stimulus and visual acuity in patients with neuro-ophthalmic disease.
