Effect of inferior oblique muscle myomectomy on choroidal and macular thicknesses in strabismus

Background: In this study, we aimed to determine postoperative changes in macular and choroidal thicknesses in patients who underwent inferior oblique myomectomy.Methods: The study included 54 eyes of 44 patients who underwent inferior oblique muscle myectomy between January 2018 and April 2022. Visual acuity and macular and choroidal thickness measurements were performed preoperatively and postoperatively (day 1, week 1, month 1, and month 3).Results: When the choroidal thickness measurements were examined, it was determined that choroidal thick-nesses decreased especially in the nasal and subfoveal regions on the first day and at the first week after surgery (p < 0.05) but approached their preoperative values at the first-and third-month evaluations (p > 0.05). The macular thickness measurements revealed an increase in all macular regions on the first day and at the end of the first week (p < 0.05) and approached their preoperative values at the end of the first and third months (p > 0.05).Conclusions: In this study, although choroidal thicknesses decreased in the early postoperative period in patients who had undergone inferior oblique myomectomy, there was an increase in macular thicknesses. However, at the third postoperative month, choroid and macular thicknesses were found to be similar to the preoperative values.
