Which acuity test is NOT considered a matching acuity test when using a lap card the patient can point to?

• A. Landolt C chart
• B. STYCAR
• C. HOTV
• D. LEA symbols

Answer: (A)

Matching acuity tests rely on the patient pointing to or selecting the symbol that matches what is seen, from a set of options presented on a lap card. The tests designed for this approach (STYCAR, HOTV, LEA symbols) let the child indicate the identical symbol from multiple choices, so the response is a straightforward matching task. Landolt C, however, is a resolution/identification test. It requires determining the orientation of a single ring with a gap (up, down, left, or right) rather than choosing among several alternatives. Because the response is about identifying the orientation of one optotype rather than matching to a target from multiple options, it is not considered a matching acuity test in this lap-card context.
