A Brief Review and Re-thinking of Proliferative Vitreoretinopathy
Prevention of proliferative vitreoretinopathy (PVR) continues to be a challenge for retinologists despite almost 30 years of research history. New diagnostic tools, based on the genetic profiles of patients with retinal detachment (RD), are now available. In addition, clinical trials in humans are about to begin of new pharmacological approaches, based on so-called ‘biological agents’. Thus, it...
متن کاملRelaxing retinotomies and retinectomies in the management of retinal detachment with severe proliferative vitreoretinopathy (PVR)
UNLABELLED Relaxing retinotomies and retinectomies are used in the presence of retinal shortening resulting from retinal incarceration or fibrous proliferation and contraction that prevents contact of the retina with the retinal pigment epithelium. The peripheral retina is usually cut or excised to preserve function of the posterior retina which is more visually significant. OBJECTIVE To inve...
متن کاملExperimental model of proliferative vitreoretinopathy (PVR) in the vitrectomised eye: effect of silicone oil.
Silicone oil alone or as an adjunct to vitrectomy is widely used for the treatment of retinal detachment complicated by proliferative vitreoretinopathy (PVR). It appears to reduce the tendency for recurrent traction detachment, but the mechanism of this action is obscure. We have studied the effects of silicone oil in an experimental animal model. Twenty five thousand homologous fibroblasts wer...

PURPOSE. Light microscopic and ultrastructural studies were perfomed in the human epiretinal membranes secondary to proliferative vitreoretinopathy (PVR).HETRODS.Humanpreretinal membranes from 5 eyes with PVR were obtained by vitrectomy. These membranes were processed for inmunohistochemical (GFAP) and electron microscopy studies to study the morphology and the cell composition. RESULTS. Light ...
