Mansukhani SA, et al. - In this retrospective, population-based cohort study, the researchers ascertained the risk of primary open angle glaucoma (POAG) following vitreoretinal surgery. Between 2004 and 2015, all residents of Olmsted County, Minnesota, undergoing scleral buckle and/or vitrectomy were involved in the operative cohort. They compared the probability of glaucoma in operative eyes and non-operative fellow eyes. The present data indicated that the risk of POAG was increased after vitrectomy.
