| Abstract |
|
In this study, we reviewed 46 consecutive patients with diagnosis of Duane's retraction syndrome at the Seoul National University Hospital from April, 1987 to October, 1995. The following characteristics were reviewed - sex, laterality, clinical type, primary position alignment, anomalous vertical movements, head turn, fusion and amblyopia. The incidence in each sex showed no difference(male: 54%, female:46%). Ninety-six percent of cases had a unilateral manifestation and 4% of cases had bilaterality. The left eyes were involved in 70% of cases and the right eyes in the 26% of cases. Type I was the most common type(96%) and the esodeviations were the most frequent in primary position. Head turns were observed in 77% of cases and the direction of head turns were toward the involved eyes in esodeviations, and away from the involved eyes in exodeviations regardless of the clinical types. Among 26 patients who underwent the fusion test, seventeen patients(65%) had fusion and that was more common in patients with exodeviation(83%) than others. |
