Minimum visual acuity: a new cone specific clinical test
Visual acuity (VA), the cornerstone of eyecare, can yield symptoms despite 20/20 [1].Optimal VA is 20/10 based on cone spacing.Vernier acuity (minimum misalignment) is 3" arc, 10x < cone spacing, a hyperacuity mediated by visual cortex [2-4].Minimum visible acuity [2] (MVA, thinnest black line detectable on white background) is 1" arc.Hence MVA (pilot avoiding fine wire), is a potential hyperacuity never used clinically.We describe a cone specific test of MVA, including
