Comitant strabismus.

ABSTRACT

This year's review of the literature on comitant strabismus is presented. The main problems in treating strabismus disorders are accurately diagnosing the condition and designing effective treatment plans. A better understanding of the underlying motility disorder facilitates a better treatment outcome. Several of this year's papers address the better detection and identification of comitant strabismus. Some patients with comitant exotropia and esotropia, however, have superimposed incomitant motility patterns such as dissociated vertical deviation. New insights into the possible etiology of dissociated vertical deviation have emerged through use of the sophisticated scleral search coil technique, which permits the discovery of minute motility changes not visible to the clinician's eye. The same technique was used to clarify the traditional clinical experience that convergence insufficiency can improve with convergence exercises.
