Fixation of the Eyeball to the Periosteum Over the Posterior Lacrimal Crest in Inveterate Exotropia

Purpose: To report the results obtained after fixation of the eyeball to the periosteum over the posterior lacrimal crest in 5 cases of inveterate exotropia. Methods: From September 2011 to January 2013, 5 patients with inveterate exotropia and a history of surgery for exotropia underwent fixation of the eyeball to the periosteum over the posterior lacrimal crest. Results: The mean preoperative exotropia of 35 ± 10.61 PD changed to esotropia of 5.8 ± 17.28 PD at the one week postoperative visit and exotropia of 13.2 ± 11.34 PD at the final postoperative visit (mean, 6.05 months after surgery). At the final postoperative visit, 2 patients who had ocular adhesion due to trauma showed 25 PD exotropia. None of the patients showed injuries to the lacrimal system, but 2 patients showed conjunctival granuloma. Conclusions: Fixation of the eyeball to the periosteum over the posterior lacrimal crest is an effective approach for the management of inveterate exotropia, except in cases of exotropia combined with ocular adhesion.
