Chua J, Ke M, Tan B, et al. - Researchers conducted this prospective study to explore the association between macular perfusion, as evaluated using optical coherence tomography angiography (OCTA), and long-term visual outcome after surgical repair of macula-off rhegmatogenous retinal detachment (RRD). The sample consisted of 29 patients who had undergone successful surgical repair of macula-off RRD. OCTA imaging was conducted at month 3 and repeated at months 6 and 12 after surgery. VA improved and FAZ area decreased over the 1-year follow-up. Better VA after surgery was significantly linked to denser superficial VD, lower number of choriocapillaris flow deficits and the larger average size of choriocapillaris flow deficits, after adjusting for baseline VA, types of surgery and other factors. OCTA measures of vascular perfusion in the macula can provide new pathophysiological insights and prognostic details related to macula-off RRD.
