[Frequency and clinical features of duane's retraction syndrome]

ABSTRACT

To evaluate the clinical features of Duane's syndrome in patients who were referred to Nikookari Eye Centre, Tabriz, as a referral centre of northwest of Iran. We retrospectively reviewed medical records of all patients with Duane's syndrome who were referred to the strabismus clinic of our center during a 5-year period [2002-2006]. Clinical and demographic characteristics were evaluated. Overall 63 patients including 36 [57.1%] female and 27 [42.9%] male subjects were enrolled which account for 2.5% of patients referred for any type of strabismus. Mean age at presentation was 10.1 +/- 7.7 [range 1-35] years. Left, right and both eyes were involved in 60.3%, 25.4% and 14.3%, respectively. The most common type of Duane's syndrome was type I [91.6%] followed by type II [6.6%] and type III [1.6%]. The most common presenting sign was eye deviation. The prevalence of amblyopia was 19% and 47.6% of patients underwent surgery. The rate of surgical intervention and the frequency of type III Duane's syndrome was very low is our series as compared to other published studies
