Patti Pics are stylized pictures designed by Precision Vision on the basis of the 5x5 Snellen grid, and calibrated for equal recognizability against Sloan letters. Visual acuity readings should not change appreciably when children are advanced from Patti Pics to a regular letter chart. This calibration helps to lessen the mistaken loss or gain of lines. Did you know that if a proportionally spaced chart is too difficult for your patients, try using a chart containing a MassVAT format. Testability using the MassVAT format in young children is high. The rectangular outline surrounding the five optotypes is 50% of the width of the optotype. Thus, it provides adequate contour interaction to detect Amblyopia.
