Nam SH, Kim K, Kim ES, et al. - Researchers conducted this retrospective study to examine longitudinal changes and associated factors for microvascular parameters in macula-off rhegmatogenous retinal detachment (RRD) after repair surgery. Thirty-four eyes with macula-off RRD were included for analysis. The foveal avascular zone (FAZ) area and parafoveal vessel density have been recorded every 3 months for 1 year after surgery. Data reported that the differences in FAZ area and vessel density between the operated and fellow eye at 3, 6, 9, and 12 months postoperatively were 0.127 ± 0.05, 0.111 ± 0.06, 0.108 ± 0.07, and 0.105 ± 0.06 mm² and 4.33 ± 1.42, 3.56 ± 2.05, 2.73 ± 1.72, and 2.61 ± 1.71/mm. After macula-off RRD surgery, microvascular parameters after successful anatomical repair were impaired but improved over 12 months. The PPV group showed significantly lower postoperative parafoveal vessel density than the buckling group.
