[Proliferative vitreoretinopathy. Pathogenesis and possibilities for treatment with cytostatic drugs].

The pathogenesis of proliferative vitreoretinopathy (PVR) is divided into five stages: (1) destruction of the integrity of vitreoretinal structures; (2) cell migration; (3) cell proliferation; (4) cell contraction, and (5) stabilization by synthesis of the extracellular matrix. Current knowledge concerning the treatment of PVR with antiproliferative drugs (5-fluorouracil, Daunomycin) is described.
