Infrequent Complications of Inferior Oblique Recession Surgery

Abstract

Purpose: To report the infrequent complications, including antielevation and adherence syndrome, after a unilateral and bilateral inferior oblique (IO) recession procedure and to discuss the possible causes. Methods: A retrospective chart review was conducted for patients on whom unilateral or bilateral IO weakening surgeries were performed. Results: Forty-three patients were included in the study. In 23 patients unilateral and in 20 patients bilateral IO weakening was performed. All patients underwent IO recession surgery. Mild limitation of elevation developed in two patients and adherence syndrome developed in one patient. All occurred after unilateral IO recession. No duction deficiency was observed in patients after bilateral IO recession. Conclusion: Antielevation and adherence syndrome can develop after unilateral IO recession surgery. Care should be taken not to tighten the neurofibrovascular bundle of the IO muscle during surgery.
