BACKGROUND: Multiple procedures have been described to treat a large-angle esodeviation with an associated abduction deficit. We report a plication augmentation of the Hummelsheim procedure for the management of esotropia and severe abduction deficit due to abducens nerve palsy or type 1 Duane syndrome. METHODS: The medical records of patients operated on using the plication augmentation Hummelsheim procedure at two tertiary centers were retrospectively reviewed. The surgery involved ipsilateral lateral rectus plication, half muscle transposition of the vertical rectus muscles to the paralytic plicated lateral rectus, Foster augmentation sutures, and ipsilateral medial rectus recession or botulinum toxin injection if it was found to be tight on intraoperative forced duction testing. Pre- and postoperative deviations, ocular motility findings, and complications were noted. RESULTS: A total of 13 patients were included, all of whom had an esotropia with profound abduction deficit (-4 or more). Postoperative deviations ranged from 14(Delta) of esotropia to 14(Delta) of exotropia, with significant improvement of the abductive motion. No patient developed anterior segment ischemia. CONCLUSIONS: The plication augmentation Hummelsheim procedure resulted in correction of even very large esodeviations and improvement of the abduction force. This procedure may also better preserve the blood supply to the anterior segment compared to other surgical approaches.
