Abstract

In 1983, the Retina Society devised a grading system for proliferative vitreoretinopathy (PVR) in hopes that a standardized grading system would make it possible to compare techniques and results of treatment for PVR from different surgeons.1 The system defines PVR as grade “A” if there is pigment proliferation in the vitreous, grade “B” if there are partial thickness retinal wrinkles and rolled edges on retinal breaks due to pre-retinal membrane contraction, grade “C” if periretinal membrane contraction produces full-thickness retinal folds involving 9 clock hours of the retina or less, and grade “D” if more than 9 clock hours of the retina are involved by such fixed folds. The “C” category is subdivided according to the number of clock hours of the retina involved by fixed folds (C-l, 1–3 clock hours; C-2, 4–6 clock hours; C-3, 7-9 clock hours). The D category is subdivided according to the degree of “funnelling” the fixed folds produce around the optic nerve (D-l, a wide open funnel; D-2, a narrow funnel defined as having its “mouth” less than 45°; and D-3, a closed funnel, such that the disc is entirely hidden at the apex of the funnel).
