The SVD and SPD in the central area, inner ring, outer ring, and full area were lower in the eyes with SO tamponade compared with the control eyes. It is unclear whether the decrease in macular microcirculation was due to RRD damage or SO tamponade duration. Agarwal et al. [The present study showed that SO might have a negative long-term effect on retinal microcirculation, as suggested by Kubicka-Trzaska et al. [Our results also showed no significant differences in SVD and SPD of the macular and peripapillary regions between the SOT contralateral and PPV + CIt should be noted that the exact mechanism underlying the increased macular capillary VDs observed after SO removal was not determined. OCTA utilizes optical measurements, and the waterproofing effect of SO seemed to have little impact on the current data. Still, it is worth further discussing this issue with expert physicists. SO filling and removal could affect OCTA data in multiple ways. Firstly, SO exerts pressure on the retina in the sitting, lateral, and prone positions. The pressure of SO on the fovea in the prone position might damage retinal structures and cause ischemia and neuronal damage [The present study had limitations. First, DCP and choriocapillaris were not assessed in the macular and peripapillary regions. Further investigation based on swept-source- and projection-resolved OCTA is required to confirm the current findings. In addition, other diagnostic parameters, including retinal thickness, foveal avascular zone (FAZ) area, contrast sensitivity, retinal sensitivity, and ETDRS letter scores, could be included in future studies to analyze the associations among various parameters. Furthermore, the present OCTA study only analyzed 6 × 6-mm
