Duane retraction syndrome: Type II with severe abducens nerve hypoplasia on magnetic resonance imaging.
Duane retraction syndrome is a congenital oculomotor disorder characterized by horizontal eye movement limitations with palpebral fissure narrowing and globe retraction on attempted adduction. Recent reports showed the absence of the subarachnoid part of the abducens nerve on magnetic resonance imaging (MRI) in types I and III. We present a case of Duane syndrome type II, in which severe hypoplasia of the abducens nerve was revealed on high-resolution MRI.
