Proliferative vitreoretinopathy.
PURPOSE. The migration, proliferation, differentiation, and adhesion of cells and other cellular functions are influenced by the surrounding extracellular matrix, in normal and wound-healing conditions. The matrix metalloproteinases (MMPs) are a family of enzymes that degrade and remodel the extracellular matrix and, thus, play a central role in the wound-healing process. Proliferative vitreore...
متن کاملA new model of proliferative vitreoretinopathy.
PURPOSE To design a new model of proliferative vitreoretinopathy (PVR) that would not rely on the addition of exogenous cells. The release of endogenous cells from surrounding attachments seems to be an early event in the pathogenesis of PVR. Because the proteolytic enzyme dispase dissociates tissues, the hypothesis was that an intraocular injection of dispase could trigger events that would ca...
متن کاملApoptosis in proliferative vitreoretinopathy.
PURPOSE To study the involvement of apoptosis using different apoptosis markers in PVR pathogenesis. METHODS The presence of mRNA coding for Fas, Fas ligand (FasL), and TNF-related apoptosis inducing ligand (TRAIL) was investigated in vitreous samples from 46 consecutive patients-25 with PVR, 11 with retinal detachment (RD) not complicated by PVR, and 10 with macular hole (MH)-using RT-PCR. F...
متن کاملThe Pathogeny of Proliferative Vitreoretinopathy.
Proliferative vitreoretinopathy (PVR) is the most important complication of rhegmatogenous retinal detachment (RRD) and the main cause of RRD surgery failure. This is a review of recent literature data, which concerns PVR pathogeny and risk factors. The occurrence of pre- and subretinal membranes is a consequence of retinal pigment epithelial cells activation and migration, with concomitant par...
متن کاملGenetic correlates of proliferative vitreoretinopathy.
The experienced retinal surgeon is familiar with the frustrating task of prognosticating and preventing/treating proliferative vitreoretinopathy (PVR) after retinal detachment (RD) surgery. The imperfection of long-described clinical models for predicting PVR leaves the surgeon questioning what underlying predispositions to PVR may exist. Rojas and colleagues provide insight into this question ...
