Effect of luminance level on contrast sensitivity in myopia.
High myopia results in stretching of the retina. We expected this stretching to impair visual function. Accordingly, we tested static and dynamic spatial contrast sensitivity and temporal modulation sensitivity at photopic, mesopic, and scotopic luminance levels. None of these functions differed significantly for high myopes (6 to 10 D) relative to age-matched normals. We conclude that retinal stretching need not induce visual deficits.
