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.

MassVAT Developed by: Luisa Mayer, Ph.D. and Bruce Moore, O.D. MassVat formats are available in many different style charts.
