Clinical features of Duane's syndrome.
This report describes the clinical findings in 70 cases of Duane's retraction syndrome. There were 25 (36%) affected males and 45 (64%) females. Left eye preponderance (67%) was observed and seven (10%) were bilateral. Type 1 cases were the most common (73%), and bilateral cases often were of different types. The features studied were primary position deviation, face turn, anomalous vertical movements, divergence in midline vertical gaze, anisometropia, and amblyopia. Horizontal saccadic velocities in ten patients were confirmatory. The significance of head positions and distance/near alignment comparisons, and the role of case classification and saccadic velocity determination are discussed.
