psychometric visual acuity
A method of measuring visual acuity that uses psychophysical techniques and forced-choice responses. It involves presenting optotypes like Tumbling E or Landolt C in varying orientations, and the patient indicates the perceived orientation. Psychometric acuity testing reduces crowding and contour interaction effects, providing more reliable measure of acuity for amblyopia.
