PURPOSE: To compare the clinical characteristics of unilateral and bilateral forms of Duane retraction syndrome.
METHODS: A retrospective chart review of patients with Duane syndrome over a 10-year span was performed. All participants underwent a complete medical and ophthalmologic examination at the time of diagnosis. Data collected included the following: sex, age at first visit, form (unilateral/bilateral), side, type, ocular duction and version, abnormal head position, best-corrected visual acuity, refractive errors, presence of strabismus, binocular function, and associated congenital anomalies.
RESULTS: Of 94 patients identified, 17% were bilaterally affected. Of the bilateral patients, 12% had familial antecedents; 87.5% had the same type in both eyes with 75% bilateral type 1. Patients with bilateral Duane syndrome had significantly different visual acuity (mean, 0.1214 logMar vs 0.0035; p = 0.045), abnormal head position (56.25% vs 89%; p = 0.04), A or V patterns (69% vs 27.6%; p = 0.003), and associated congenital anomalies (50% vs 14%; p = 0.003) than patients with unilateral disease. There was also a suggestion of higher rates of ametropia, global vertical dysfunction, and abnormal stereoacuity in bilateral Duane syndrome that were not statistically significant.
CONCLUSIONS: Patients with bilateral Duane syndrome had lower visual acuity, a lower incidence of abnormal head posture, and a higher incidence of A or V patterns and associated congenital anomalies. Bilateral Duane retraction syndrome seems to involve multiple instances of deinnervation and fibrosis, resulting in horizontal and vertical oculomotor deficits and functional impairments.
