title: Fixation preference for the affected eye in patients with unilateral Duane syndrome.
abstract: Duane retraction syndrome is a congenital incomitant strabismus caused by dysinnervation of the medial and lateral rectus muscles. Patients with unilateral Duane syndrome (80-90% of cases) who exhibit a fixation preference tend to prefer the unaffected eye. We describe 8 patients with unilateral Duane syndrome who prefer the affected eye. The most frequent associated ophthalmic finding was decreased vision in the unaffected eye from anisometropia and/or amblyopia. An additional associated finding was decompensated intermittent exotropia in 2 patients.
