- W4312080306 abstract "Purpose: To investigate macular microvascular changes using OCTA in patients one-year after a successful RDD surgery. Methods: Cross-sectional study including RRD treated using PPV ± SB and SF6 tamponade. Eyes were divided related to their macular status previous surgery and depending on the surgical technique used. All the subjects underwent complete ophthalmological examinations including a 3x3 OCTA protocol using DRI-Triton swept source (SS)-OCT with a minimum 12 months follow-up after the surgery. Retinal capillary plexuses and CC vessel density (VD) were studied. FAZ area and diameters were measured. Results were compared with the unaffected contralateral eye. Results: Sixty eyes of 57 patients with RRD were included. Mean age was 59.14 ± 9.52 years. PPV was performed in 68.3% of the eyes, associated to SB in 31.6%. The macula was affected in 38.3% of the eyes and unaffected in 61.7%. RRD macula-off had lower VA than the contralateral eyes. No differences were observed in VD between RRD macula-on eyes regardless of the surgical technique performed. However, one year after surgery, we observed a significantly increased VD in the central area of macula-off RRD eyes treated with PPV + SB in both retinal plexuses and in the SCP of RRD treated with PPV compared to the fellow eyes. All the macula-off treated eyes had a diminished VD for both SCP and DCP in the superior quadrant and in PPV + SB we also found a diminution in the inferior quadrant for the SCP. In the inferior quadrant, we only found a diminution in the SCP flow in macula-off treated with PPV + SB. We found changes at the CC level in the temporal quadrant of the macular-off treated with PPV + SB. We did not observe differences in FAZ area between any groups. FAZ horizontal and vertical diameters were statistically smaller in patients with macula-off RRD. Conclusion: Macular vascularity remains almost unchanged in patients one year after successful RRD surgery, despite the surgical technique (VPP vs VPP + SB). Vascular changes are not remarkable in neither macula-on not macula-off RDD. We found an increase in VD in the central area of the retinal capillary plexus in patients after macula-off RDD associated to a diminution in VD of both superior and inferior quadrants of the retinal plexuses suggesting changes in vascularization after macula-off RRD surgery." @default.
