The “Duration” represents “Duration of SO tamponade”; “Follow-up time” represents the follow-up time after silicone oil removal surgery; "Detachment time" represents the interval between retinal detachment and surgery; SCPVD, DCPVD, and RNFLT are all values of the parafoveal area
SO silicone oil, BCVA best corrected visual acuity, FR fixation rate, MRS mean retinal sensitivity, SCP superficial capillary plexus, DCP deep capillary plexus, VD vascular density, RNFLT retinal nerve fiber layer thickness, FMT foveal macular thickness, FAZ foveal avascular zone
