Patti Pics™ Series ETDRS®

The Patti Pics™ Series ETDRS® chart family — Chart 1, Chart 2, Chart 3, or the full Set of 3 — for pediatric and preliterate visual acuity testing across the four standard ETDRS distances (2 m, 2.5 m, 3 m, 4 m).

Patti Pics replaces letters with universally recognizable symbols (apple, house, square, circle), making the same Logarithmic ETDRS protocol accessible to children and non-readers without compromising clinical rigor. Use Charts 1, 2, and 3 in rotation as alternate-form charts to eliminate learning effects across repeat visits or between eyes.

Designed to fit the 2425 / 2425 LED Large ETDRS® Illuminator Cabinets.
