Purpose: To evaluate the structural and microvascular changes in the retina and choroid after strabismus surgery. Methods: The study included 44 eyes from 44 patients who underwent strabismus surgery between August 2020 and December 2021. Among these patients, 9 (20%) underwent horizontal one-muscle surgery, 27 (61%) underwent horizontal two-muscle surgery, and 8 (18%) underwent inferior oblique muscle anteriorization surgery. Optical coherence tomography angiography scans were conducted preoperatively and at 1 day, 1 week, 1 month, and 3 months postoperatively. Results: The outer retinal blood flow showed a significant increase at 1 day postoperatively in horizontal two-muscle and inferior oblique muscle anteriorization surgery, whereas no significant difference was observed between periods in horizontal one-muscle surgery (P =.007). Choriocapillaris blood flow exhibited a significant increase at 1 day and 1 month postoperatively compared to the preoperative period (P <.001). Whole image superficial capillary plexus vascular density was significantly lower at 1 day postoperatively than preoperatively and 1 and 3 months postoperatively (P <.001). Whole image deep capillary plexus vascular density was significantly lower at 1 day than at 1 month postoperatively (P =.002). Conclusions: Following strabismus surgery, temporary changes in the hemodynamic microcirculation in the retina and choroid are observed. A transient decrease in retinal artery blood supply may be noticed, possibly attributed to the reduced anterior segment blood supply.
