It has only been described once in a case of congenital fibrosis of the extraocular muscles.² Here we describe a girl with isolated congenital synergistic convergence and discuss its probable pathophysiology.

Report of a Case

A 5-year-old girl had orthophoria and reduced stereovision in primary position. On right gaze, she fixated with the left eye in adduction, and a large esotropia of about 52 prism diopters () appeared. On . . . [Full Text of this Article]
