Lateral rectus recession for consecutive exotropia in esotropic Duane syndrome: A case report

Abstract

Consecutive exotropia is considered as a rare complication after medial rectus recession that is performed for cases of esotropic Duane syndrome. Here, we present a case of 5-year-old female initially presented with the limitation of abduction, narrowing of the palpebral fissure, and globe retraction of the left eye along with a mild left face turn. She was diagnosed with Duane syndrome Type 1. She was treated with the medial rectus recession (6.5 mm). Postsurgery, she developed a consecutive exotropia. This was managed successfully with the ipsilateral lateral rectus recession (8 mm). Following this surgery, the patient was orthoptic in the primary position and her abnormal head posture was markedly improved.
