title: A retinoscopic method of assessing accommodative performance of young human infants.
abstract: A retinoscopic method of assessing changes of the accommodative status of the young human infant with changes of the stimulus viewing distance id described. This method utilized dynamic retinoscopy and a series of patterned visual stimuli. Vertical, above-threshold, squarewave gratings presented at viewing distances of from 10 through 50 centimeters were utilized as fixation and accommodation stimuli. During fixation of the stimuli by the infants, the refractive state of the eyes was determined by location of the conjugate retinal focus. Comparison of the refractive state of the eye to the magnitude of the accommodative stimulus at a particular viewing distance can be utilized as an index of the accuracy of the accommodative response. The applicability of this retinoscopic method to private clinical practice is discussed.
