Detection of macular changes by optical coherence tomography after inferior oblique muscle surgery

PurposeTo detect macular changes after inferior oblique muscle myectomy and anterior transposition by the use of 3-dimensional optical coherence tomography (OCT).MethodsPatients who received surgery for correction of horizontal strabismus and weakening of inferior oblique muscle overaction were included. OCT was performed shortly before surgery and again 1 day, 1 week, and 1 month postoperatively.ResultsA total of 23 eyes of 16 patients were included. OCT showed no significant macular changes after inferior oblique myectomy or anterior transposition.ConclusionsWe documented no harmful effects on the macula after manipulation of the inferior oblique muscle during standard weakening procedures.
