what is proliferative vitreoretinopathy stages
Proliferative vitreoretinopathy (PVR) is a disease that develops as a complication of rhegmatogenous retinal detachment. number of cytokines such as tumor necrosis factor alpha (TNFÎ±), transforming growth factor beta 2 (TGFÎ² 2), platelet derived growth factor (PDGF) and interleukins have been shown to play a role in PVR progression.
PVR occurs in about 8â10% of patients undergoing primary retinal detachment surgery and prevents the successful surgical repair of rhegmatogenous retinal detachment. PVR can be treated with surgery to reattach the detached retina but the visual outcome of the surgery is very poor.PVR was originally referred to as massive vitreous retraction and then as massive periretinal proliferation. The name Proliferative vitreo retinopathy was provided in 1989 by the Silicone Oil Study group. number of cytokines such as tumor necrosis factor alpha (TNFÎ±), transforming growth factor beta 2 (TGFÎ² 2), platelet derived growth factor (PDGF) and interleukins have been shown to play a role in PVR progression.
