Abstract

Cyclic esotropia is a very rare and specific entity. Cyclic esotropia is sometimes developed in a patient following strabismus surgery for intermittent exotropia. The term of 'consecutive cyclic esotropia' was suggested for this clinical entity. Three cases of consecutive cyclic esotropia have been reported in U.S.A., Canada and Japan, and only one case has been reported in Korea. We experienced two cases of consecutive cyclic esotropia which developed 10 months and 1 year after strabismus surgery for intermittent exotropia at our hospital. The patients underwent bimedial rectus recessions and results are uniformly good, with straight eyes and fusion. The cyclic pattern does not recur. We report these patients with a review of the literature.
