Objective: To determine the clinical properties of Duane's Retraction Syndrome (DRS) cases in our clinic, to emphasize the importance of differential diagnosis in these patients. Materials and methods: Gender distribution, laterality, type of the syndrome, amblyopia, and accompanying ocular and non-ocular abnormalities of the 32 cases that were diagnosed as Duane's retraction syndrome were retrospectively investigated. Results: Thirty-two cases with average age of 7.40±3.34 were followed for 14±5.20 months at average. Twenty (62.5%) of the 32 cases of were female and 12 were male (37.5%). Twenty-seven of the cases (84.7%) were type-I, 4 was type-II (12.5%), and 1 was type-III (3.12%) DRS. Twenty-five (78.1%) of the cases had one eye involvement and 7 (21.9%) had two eyes involvement. Left eye involvement among cases with one eye DRS were higher (56.2%). In type-I DRS cases the rates of exotropia, amblyopia, up-shoot and down-shoot, and abnormal head posture were as follows 43.75%, 28%, 34.37%, 37.20%, respectively. Patients who were applied Magnetic Resonance Imaging techniques had no abnormality about intracranial structure. Five among type-I DRS cases who had serious abnormal head posture had medial rectus recession operation. Conclusion: The majority of Duane retraction syndrome cases were constituted of Type I cases. It was observed that the syndrome was more frequent in women and left eye was more affected. While visual acuity was observed as normal in majority of cases, in some cases exotropia, amblyopia, and abnormal head posture were present. Significant improvements were observed in terms of slippage angles and head postures of 5 cases with type 1 DRS after surgery.
