Proliferative Vitreoretinopathy
Survey of Ophthalmology, 1998Proliferative vitreoretinopathy (PVR) is still the most common cause of failure of surgery for rhegmatogenous retinal detachment, despite the substantial effort that has been devoted to better understanding and managing this condition during the past 25 years. Basic research has indicated that PVR represents scarring, the end stage of the wound-healing

Iris Neovascularizadon in Proliferative Vitreoretinopathy
Ophthalmology, 1992The purpose of this study is to report on the prevalence, incidence, and associated risk factors of iris neovascularization in nondiabetic patients undergoing vitrectomy for retinal detachment complicated by proliferative vitreoretinopathy (PVR).The authors conducted a retrospective review of 141 consecutive non-diabetic patients undergoing vitrectomy ...

Molecular Targets for Proliferative Vitreoretinopathy
Seminars in Ophthalmology, 2021While innovations in the surgical management of retinal detachment (RD) with proliferative vitreoretinopathy (PVR) have significantly improved anatomic and visual outcomes over the years, recurrent RD due to PVR remains the major limitation to success. There are currently no medical therapies proven to be effective against PVR in humans.

Osseous metaplasia in proliferative vitreoretinopathy
American Journal of Ophthalmology, 1998To 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 ...

Risk factors for proliferative vitreoretinopathy
Current Opinion in Ophthalmology, 1995Despite the recent progress in vitreous surgery, treatment of proliferative vitreoretinopathy (PVR) is still difficult. Even if the reattachment of the retina is successful, visual prognosis is often unsatisfactory. Identification of clinical risk factors for PVR provides useful guidelines for planning the management of rhegmatogeneous retinal ...

Surgical Treatments of Proliferative Vitreoretinopathy
Archives of Ophthalmology, 1984Four hundred ten eyes with retinal detachment and proliferative vitreoretinopathy underwent closed vitrectomy with membrane peeling, scleral buckling, and intraocular air injection. The retina was reattached in 243 eyes (59.3%). Useful vision was attained in 223 eyes.

Retinal Detachment and Proliferative Vitreoretinopathy
2010In 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

Inherited Proliferative Vitreoretinopathies of Childhood
International Ophthalmology Clinics, 2008There 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 ...

Immunohistologic Study of Proliferative Vitreoretinopathy
American Journal of Ophthalmology, 1989An 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 ...

The effects of pleiotrophin in proliferative vitreoretinopathy
Graefe's Archive for Clinical and Experimental Ophthalmology, 2017The 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.
