Abstract: Rhegmatogenous retinal detachment (RRD) is mainly treated by surgery, and anatomical reattachment can be achieved in most patients after surgery, but the visual improvement is often not obvious. Optical coherence tomography angiography (OCTA) can observe the area of foveal avascular zone in the fovea of macular, the vessels density of retinochoroid in macular area and the capillary density around optic disc. Dynamic follow-up of postoperative choroidal and optic disc microvascular changes has important guiding value for the analysis and prediction of visual function in patients with RRD.
