Proliferative vitreoretinopathy: the rabbit cell injection model for screening of antiproliferative drugs.

Injection into the rabbit vitreous of cultured cells results in a condition that mimics some of the features of proliferative vitreoretinopathy (PVR) in man. Because of its simplicity and reproducibility, this model is especially useful for screening drugs that may control or inhibit intraocular cell proliferation. The cell injection model of PVR is reviewed, and some modifications are described.
