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.
对28例（39次手术）间歇性外斜视病例进行了回顾。手术前先进行棱镜矫正，并逐渐增加度数以稳定客观斜视角。手术量的计算旨在实现轻微的过度矫正（约5度）。随访6个月发现，若实现了过度矫正，则效果更佳。若手术未适当考虑客观斜视角的远/近比例关系，会出现连续性内斜视。二次手术可推迟至6个月。在任何过度矫正的情况下，均先进行戴镜遮盖，然后使用底向外棱镜，直至能维持双眼注视。
