Prior studies have found a reduction in contrast sensitivity in eyes with amblyopia using sinusoidal gratings,^1-3 whereas minimal loss has been reported with Pelli-Robson charts.^3-4 Most studies have evaluated contrast sensitivity at the time of diagnosis of amblyopia or after short-term treatment. A follow-up study of an earlier randomized trial provided us the opportunity to evaluate contrast sensitivity using Pelli-Robson low-contrast letter charts at age 10 years, several years after treatment of amblyopia.⁵

Methods

Contrast sensitivity was measured using Pelli-Robson charts⁵ (Richmond Products, Albuquerque, New Mexico) in 86 subjects (mean age, 10.3 years) who at ages 3 to 6 years had participated in a randomized treatment . . . [Full Text of this Article]
