Clinical course of a consecutive esotropia from an strabismus surgery. Case Report

Abstract

Purpose: to analyze and describe the clinical course of a recurrent exotropia, which after re-surgery developed a consecutive esotropia. <em><strong>Methods:</strong></em> female subject, 4 year and 5 months old, with an intermittent exotropia diagnosis. A retro insertion of the lateral rectus to 6,5 mm in both eyes was performed. Exotropia reappeared in one year. Subsequently, a 6 mm resection of both middle rectus was performed. The postoperatory result was a self involutive consecutive esotropia. <em><strong>Results:</strong></em> after first surgery for exotropia, a micro esotropia was obtained and it evolved to recurrent exotropia. In the new surgery a 20 prismatic diopters consecutive esotropia was obtained and it is currently involutioning. <em><strong>Conclusion:</strong></em> an hypercorrection should be considered in the procedure. In the case of a second surgery for recurrent exotropia, it should be considered that exotropia could reappear, although in a less recurrence rate that in the first one, so another hypercorrection should be considered too. Postoperative esodeviation after exotropia surgery tends to diminish and stop persisting after six months.
