Tsen CL, et al. - Researchers examined 28 patients (28 eyes) who underwent successful repair of macula-off rhegmatogenous retinal detachment (RRD) using optical coherence tomography angiography (OCTA) for changes in the microcirculation of various retinal layers and choroid following successful repair of macula-off RRD. Comparing differences in OCTA characteristics between retinal detachment (RD) and fellow eyes, they identified significantly lower mean vessel and parafoveal vessel densities in the superficial retinal capillary plexus (SCP) and deep retinal capillary plexus in the RD eyes than the fellow eyes. Observations suggest the occurrence of retinal structural damage as well as a decreased retinal perfusion even after successful anatomical repair in correlation to macula-off RRD. The combined procedure, vs a scleral buckle or vitrectomy alone, might result in a lower vessel density.
