Proliferative vitreoretinopathy (PVR) is a cellular proliferation producing ‘epiretinal membranes’ in rhegmatogenous retinal detachment. Primary RRDs which have been present for weeks or months are likely to develop PVR. At presentation, the rate of PVR in all patients with RRD varies depending on the ease of access to health care; where prompt surgery is available, PVR rates of 5 % are expected; however, where there is delay in receiving surgery, PVR rates are much higher, for example, 53 % in South America (Tseng et al. 2004) and 17.5 % in East Africa (Yorston et al. 2002). Failed surgery increases the risk of postoperative PVR which has been reported in 5 % of RRDs with U tears, 18 % with paravascular tears and 25 % of giant retinal tears (Bonnet et al. 1996).
