Outline

Text

The VIPER Study is a randomized controlled multi center trial performed within the framework of retina.net. The study is designed to evaluate the efficacy and safety of an additional encircling band in the treatment of pseudophakic retinal detachments with primary vitrectomy. 233 patients will be recruited in 15 sites and randomized to one of the following groups: 20 G ppV (n=100), 20 G ppV + encircling band (n=100), 23/25 G ppV (n=33). Primary outcome parameter is single surgery success after a follow-up of six months. Secondary parameters are best corrected visual acuity, refractive changes, and other side effects. Currently 92 patients are enclosed. A universal data bank management system is used to perform this study. We will explain the study design, recruitment data and preliminary results.
