Evaluation of macular thickness change after inferior oblique muscle recession surgery.

PURPOSE

This study aimed to evaluate the changes in macular thickness following inferior oblique muscle recession surgery.

MATERIALS AND METHODS

Thirty-eight eyes from 21 patients undergoing ocular muscle surgery were included. Patients were grouped into three groups based on the type of surgical intervention: Group I (n = 12), inferior oblique recession surgery alone; Group II (n = 12), inferior oblique plus horizontal muscle surgery; Group III (n = 14), horizontal muscle surgery alone. Each eye was scanned using the optical coherence tomography (OCT) device preoperatively and on the first postoperative day to measure macular thickness.

RESULTS

Following surgery, a significant increase in foveal thickness occurred in Group I (P < 0.05) and Group II (P < 0.01). In addition, a statistically significant difference was observed between the groups with regard to the increase in foveal thickness (P = 0.016), with significantly lower changes in Group III.

CONCLUSION

Our findings suggested that inferior oblique muscle recession surgery is associated with an increase in macular thickness.
