Retinal displacement refers to the strong fluorescent lines parallel to the retinal vessels that are detected through autofluorescence examination after rhegmatogenous retinal detachment (RRD) surgery. Actually, even if patients with RRD achieve macroscopic structural reattachment after the operation, the visual function of some patients remains suboptimal. This is associated with the incomplete recovery of retinal function, and retinal displacement is one of the critical influencing factors. This paper reviews the related concepts of retinal displacement and systematically summarizes the incidence of retinal displacement after retinal reattachment surgery and its impact on function, the possible mechanisms of retinal displacement, and the influence of various factors on the occurrence of retinal displacement in the recent five years. It is conducive to enabling surgeons to conduct better design and planning for retinal reattachment surgeries, then achieve higher integrity of retinal function recovery, and enable patients to obtain better postoperative visual function.
