Significant immediate and long-term reduction of astigmatism after lateral rectus recession in divergent Duane's syndrome.

Duane's syndrome is associated with anisometropia and amblyopia. We encountered 1 patient with right divergent Duane's syndrome (type 2 according to Huber's classification) with high astigmatism of the right eye and a head turn. In order to improve the head turn and thereby avoid eccentric gaze through the glasses, the right lateral rectus muscle was recessed by 7.75 mm. Postoperatively, the amount of astigmatism was reduced by 1.5 dpt with no change of the axis. This change of refraction remained stable over a follow-up time of 18 months.
