We developed an experimental model of proliferative vitreoretinopathy (PVR) in albino rabbits by combining some factors suspected of causing the di sease. Sixty nine eyes divided into six groups served as controls (Groups C 1–6). Forty nine eyes were divided into four experimental groups (Groups E 1-4). Group El (n=12) was injected with 0.15 ml of platelet-rich plasma. In addition, Groups E2 (n=12) and E3 (n=12) underwent cryotherapy or vitrectomy. Group E4 (n=13) underwent both procedures. Seven of the 13 Group 4 experimental eyes developed total retinal detachment and giant holes. None of the other groups developed more than two total retinal detachments or giant holes (P<0.05). Light and electron microscopy showed Intravitreal or freretinal proliferation composed of ibroblast-like cells. Retroretinal membranes appeared only in Group E4 eyes, composed of elongated cells with oval nuclei and abundant organelles in the cytoplasm. We believe these lesions mimic human PVR more closely than other models previously developed.
