[Results of surgical treatment in intermittent divergent squint with deliberate overcorrection (author's transl)].

A review is given of 28 cases (39 surgical procedures) with intermittent exotropia. Prior to surgery a prismatic correction was prescribed and gradually increased to stabilize the objective angle. The amount of surgery was calculated to give a slight overcorrection (approximately 5 degrees). Follow up over a 6 months period revealed better results if overcorrection was achieved. Consecutive esotropia occured if the surgery did not make proper allowances for distance/near ratios of the objective angle. Secondary surgery was delayed up to 6 months. Spectacle occlusion followed by base-out prisms were prescribed in any case of overcorrection until bifoveal fixation could be maintained.
