Non-Asthenopic Convergence Insufficiencies

Abstract

Convergence insufficiency is usually related to asthenopic symptoms along with the classic findings of remote near point of convergence, low convergence amplitudes at near, and an exophoria at near. This study evaluated 20 randomly selected young adults for convergence insufficiency findings and/or symptoms. Of the 20 subjects, three displayed different degrees of convergence insufficiency. Mild asthenopic symptoms were admitted upon questioning by one of the three. The other two were free of asthenopia. Subjects exist as a silent portion of the general population with non-asthenopic convergence insufficiency, in addition to those individuals diagnosed by classic signs and symptoms.
