Patti Pics are calibrated symbols used for vision testing for pediatrics. These symbols include a House, Apple, Square, Circle and Star. They are calibrated to Sloan standards and help to minimize mistaken loss or gain of lines when the patient transitions from pediatric charts to adult charts. Coupled with a MassVat design, Patti Pics charts are highly accurate and usable for pediatric testing.
