Retinal displacement following repair of rhegmatogenous retinal detachment

Retinal displacement following the repair of rhegmatogenous retinal detachment (RRD) has been reported in recent studies. It was described as vertical movement of the retinal relative to its original location, as evidenced by retinal vessel printing on fundus autofluorescence imaging. This review reports the current literature on retinal displacement. We conducted an English literature search using Medline, PubMed, Embase, and Web of Science. We have reviewed 22 articles describing the diagnosis, frequency, and possible risk factors for retinal displacement. The reported rate of retinal displacement ranged from 6.4% to 62.8%, and the possible risk factors included the detachment-to-repair time, location and extent of RRD, macula-off RD, presence of subretinal fluid, use of perfluorocarbon, use of tamponade, postoperative facedown positioning, type of RRD repair, and presence of proliferative vitreoretinopathy, especially high grade. This review increases awareness of retinal displacement and its associated visual effects.
