proliferative vitreoretinopathy
Pronunciation: proh-LIF-er-ah-tiv VIT-ree-oh-ret-in-OP-ah-thee
A serious complication of retinal detachment characterized by formation of scar tissue that can cause recurrent detachment.
Full Definition
Proliferative vitreoretinopathy (PVR) is a complex wound healing response following retinal detachment or trauma, characterized by the formation of cellular membranes on retinal surfaces and within the vitreous cavity. These contractile membranes can cause retinal distortion, fixed folds, and recurrent detachment that is difficult to repair. PVR is graded using standardized classification systems and represents one of the most challenging complications in vitreoretinal surgery. Treatment typically requires complex surgical techniques including membrane peeling, vitrectomy, and often multiple procedures to achieve anatomical success.
Usage
Usage note: Commonly abbreviated as 'PVR' in surgical notes; use grading system when applicable.
