Proliferative vitreoretinopathy (PVR) is a leading cause for loss of vision in which the retinal pigment epithelial (RPE) cells proliferate and result in traction retinal detachment. Inhibition of intraocular cellular proliferation can therefore be of help to prevent and treat PVR. We have shown that inflammatory cytokines play key roles in the development of PVR. In our series of experiments using human cultured RPE cells, human intraocular proliferating membranes and animal models, we observed effects and mechanism of anti-cytokines or inhibition in gene level to the cell proliferation, including interleukine 1 receptor antigonist (IL-1ra), interleukine 6 antisense oligonucleotide, (IL-6-ASON), dexamethasone or daunorubicin, and hypercin, a protein kinase C (PKC) specific inhibitor. Those agents or drugs all showed inhibition of expression of related molecules and cellular proliferation of RPE cells, and reduction of development of PVR in the model. 18 papers, and 4 M.D. and 5 M.S.yield from those research work.
