Proliferative vitreoretinopathy (PVR) can complicate up to 10% of all retinal detachment repairs, so getting to the bottom of its development can save patients significant grief.1 A new retrospective, case–control study, published in the journal Retina, seeks to identify predictive factors for the condition.2 The study examined 74 eyes, which were divided equally into two groups, one with and one without PVR after surgery.2 The researchers found that PVR formation was 4.2 times more likely for retinal detachments that involved the macula.2 Additionally, PVR was 3.6 times more likely in smokers and even former smokers.2 The researchers also considered factors such as the duration of retinal detachment symptoms, high myopia, lens status, lattice degeneration, location of retinal break, number of retinal breaks and surgical technique; however, none were found to have a significant impact.2
