The aim was to evaluate retinal and choroidal microcirculation using optical coherence tomography angiography after strabismus surgery. This was a cross-sectional observation study of 44 eyes of 44 patients. Patients were split into three groups: (1) one-muscle horizontal surgery (n=9); (2) two-muscle horizontal surgery (n=27); and (3) inferior oblique anteriorisation (n=8). There were 30 males and 14 females with mean age of 23 ±14 years. Right eye surgery was in 23 cases and left eye surgery for 21. There was no difference for foveal avascular zone across groups or for choriocapillaris blood flow and central macular thickness values. There were temporary changes for outer retinal blood flow (increased) in groups 2 and 3, and whole image superficial capillary plexus vascular density (lower). There is potential direct proportionality between the number of operated muscles and the severity of inflammation.
