Purpose: The Pacific Acuity Test (PAT) is a new vanishing optotype test designed to measure recognition visual acuities in preverbal children using a face and opposing oval figure in a forced-choice preferential looking format. This study evaluates the testability, validity, and interobserver reliability of the PAT.
Methods: Fifty-two subjects, aged 6 to 36 months, were tested by a primary observer to determine both recognition and resolution visual acuities using the PAT.
