Osseous metaplasia in proliferative vitreoretinopathy

American Journal of Ophthalmology, 1998
To report the clinicopathologic features of intraocular osseous production in association with proliferative vitreoretinopathy.The clinical and histopathologic features of two patients with proliferative vitreoretinopathy and intraocular bone formation are reviewed.Preretinal osseous tissue incorporated in the proliferative vitreoretinopathy was ...

Inherited Proliferative Vitreoretinopathies of Childhood

International Ophthalmology Clinics, 2008
There are a number of inherited, childhood disorders of the retinal vasculature that result in vitreoretinal proliferation. These include familial exudative vitreoretinopathy (FEVR), Norrie disease (ND), incontinentia pigmenti (IP), autosomal dominant neovascular inflammatory vitreoretinopathy ...

Retinal Detachment and Proliferative Vitreoretinopathy

2010
In normal eyes, retinal detachment (RD) occurs at a rate of approximately 5 per 100,000 people per year and the frequency of proliferative vitreoretinopathy (PVR) remains largely unchanged in primary RD, with the incidence ranging from 5.1 to 11.7%. PVR is the most common cause of failed repair of rhegmatogenous RD, and risk factors for PVR are related

The effects of pleiotrophin in proliferative vitreoretinopathy

Graefe's Archive for Clinical and Experimental Ophthalmology, 2017
The purpose of our study was to investigate the effects of pleiotrophin (PTN) in proliferative vitreoretinopathy (PVR) both in vitro and in vivo.Immunofluorescence was used to observe the PTN expression in periretinal membrane samples from patients with PVR and controls. ARPE-19 cells were exposed to TGF-β1.

Surgical Results for Proliferative Vitreoretinopathy [PDF]

European Journal of Ophthalmology, 1994
We reviewed 88 consecutive eyes that underwent vitrectomy for retinal detachment with proliferative vitreoretinopathy (PVR) and were followed a minimum of six months. A primary goal of the surgery was the meticulous trimming of the vitreous base in hopes of decreasing the incidence of postoperative reproliferation and anterior PVR.

Immunohistologic Study of Proliferative Vitreoretinopathy

American Journal of Ophthalmology, 1989
An immunohistologic study was performed on pars plana specimens obtained by biopsy in ten patients with rhegmatogenous retinal detachment, with or without proliferative vitreoretinopathy. Using immunofluorescence or immunoperoxidase procedures, linear deposits of IgG, IgA, and complement components were found in the eight cases of retinal detachment ...

In vivo models of proliferative vitreoretinopathy [PDF]

Nature Protocols, 2007
We outline current in vitro and in vivo models for experimental proliferative vitreoretinopathy (PVR) and provide a detailed protocol of our standardized in vivo PVR model. PVR is the leading cause of failed surgical procedures for the correction of rhegmatogenous retinal detachment.

Proliferative vitreoretinopathy and chemotherapeutic agents

Survey of Ophthalmology, 1985
Proliferative vitreoretinopathy (PVR) is a disease process that occurs in eyes with rhegmatogenous retinal detachments and accounts for the majority of failures following retinal detachment surgery. PVR involves the uncontrolled proliferation of non-neoplastic cells capable of forming membranes, which may occur on either surface of the retina or along ...

Spontaneous resolution of proliferative vitreoretinopathy

Acta Ophthalmologica, 1992
Abstract A case of proliferative vitroretinopathy that spontaneously regressed, leading to reattachment of the retina, is presented. The importance of such a spontaneous resolution in terms of understanding the pathogenesis, and planning a treatment, is discussed.
