How to predict proliferative vitreoretinopathy

摘要: Abstract Purpose To determine prospectively the accuracy of a predictive risk formula for development postoperative proliferative vitreoretinopathy (PVR) when applied in clinical setting. Design Prospective noncomparative interventional case series. Participants Two hundred nineteen subjects undergoing primary vitrectomy rhegmatogenous retinal detachment were studied. Method By use formula-based discriminant rule, classified as either high or low PVR. All followed prospectively. Outcome measures Development PVR defined by updated Retina Society Classification. Results Complete data available on 212 219 subjects. There 130 identified and 82 risk; 9.2% low-risk (12 130) compared with 28% (23 82) high-risk had develop. This difference was statistically significant ( P Conclusions Our study has shown that using model it is possible to identify at greater developing after vitrectomy.
