Background: Suppression is a phenomenon whereby an individual develops the ability to ignore a part of their binocular visual field. This condition is associated with binocular vision conditions such as amblyopia and anisometropia. Current commercial methods of testing suppression measure only foveal or central suppression at one test distance. Purpose: The purpose of our study was to assess a new suppression target on an iPad that provides consistent luminance and assesses foveal and central suppression at one testing distance. Methods: Subjects aged 3 and older that presented for a routine eye examination at The Ohio State College of Optometry were invited to participate in our study. Routine testing including visual acuity, dry and wet refraction/retinoscopy, stereopsis and cover test were performed by the doctor and recorded by the examiner. Each of the suppression tests were then performed by the examiner in a random order, and repeated with the colored filters reversed. The results for each test were recorded. Cross-tabulation and McNemar chi-square analysis was used to compare the suppression testing devices. Results: Fifty subjects were enrolled (mean age = 17.5). Twelve subjects reported suppression and one reported diplopia. Testability was excellent for all tests. There was no significant difference between tests in reported suppression, with all p values equal to .22 or greater. No difference in reported suppression was observed with change in orientation of the anaglyphic filters. Six subjects reported foveal suppression alone at near which was not identified with Worth 4 dot. Conclusion: The iPad test of suppression provided high testability and excellent agreement with commonly used tests of suppression.
