Acute Acquired Concomitant Esotropia Recurrence

Introduction: Acute acquired concomitant esotropia (AACE) is a rare type of esotropia. Type II AACE associated with physical stress or psychological stress (Franceschetti type) has been reported to respond well to surgical or botulinum toxin treatment. Regarding the recurrence of deviation in AACE on long term follow-up there is very few information available in the literature.

Methods: In this poster we review four cases of type II AACE with excellent initial results following treatment, where the deviation and symptoms recurred.

Results: Esotropia recurred in these patients after initial resolution with excellent ocular alignment and binocularity, in conditions of emotional and visual stress, in one case the deviation reappeared 5 years after initial surgery. The recurrent esodeviation was approached with surgery or prisms correction.

Conclusion: Recurrence of symptoms in AACE may appear even after long period of good alignment and high binocularity.
