title: A procedure for measuring the near-point fusional vergence reserves of young children.
abstract: This paper describes a modification of the standard method for measuring near-point fusional vergence reserves that reduces dependency upon patient's verbal responses by employing a fixation target that can be perceived accurately only when viewed binocularly. As such, the procedure is particularly useful with young children whose subjective responses often tend to be unreliable. Data from 34 preschool children are reported.
