Visual and Orthoptic Training

Abstract

Visual and orthoptic exercises are advocated for all cases of concomitant strabismus, either as a complete procedure or as supplementary to operation. Visual exercises concantrate on developing rapid and steady fixation, dynamic form vision, and accurate projection and orientation. Orthoptic exercises tend to arouse, first, biperipheral vision, then bimacular vision, overcoming macular resistance by means of identical or compatible images presented for fusion. Exercises which develop hand and eye movements in a common binocular field of projection are especially good. To check on fusion as against suppression the bimanual projection test is used in addition to the control marks in the stereoscope or amblyoscope. This is an abstract of a paper read before the Eastern New York Eye, Ear, Nose and Throat Association, at Schenectady, November 22, 1933.
