Management of Retinal Detachment with Moderate PVR

Retinal detachment with moderate degrees of proliferative vitreoretinopathy (PVR, Retina Society classification,1 Grade B) is recognized clinically as wrinkling of the retinal surface, and/or curled edges of retinal breaks. The detached retina appears to have stiffness with retinal vessels in the affected areas exhibiting increased tortuosity. Often the epiretinal membranes are clinically invisible, but as proliferation becomes more severe (Grade C) the membranes become visible and cause full-thickness fixed or star folds. A localized form of moderate proliferative vitreoretinopathy that deserves special consideration is retinal detachment with macular pucker.
