Convergence Insufficiency and Duane’s Retraction Syndrome
Ingrid Simon, Assoc.Dip.O. (Cumb), DOBA
A review of 37 cases of Duane’s retraction syndrome revealed asthenopic symptoms in association with defective convergence in 22 cases. In some, symptoms were relieved by conventional convergence exercises. Evidence suggests that the presence of symptoms and the possibility of relieving them is often overlooked in such cases.
