Malignant glaucoma after XEN45 implant.

Minimally invasive glaucoma surgery for chronic open-angle glaucoma treatment tries to reduce the amount of chronic topical drug treatment, delaying invasive glaucoma surgery and diminishing the number of surgical complications. XEN45 uses subconjunctival drainage in order to reduce intraocular pressure. The report is presented of a patient following phacoemulsification, intraocular lens implantation and XEN45 implant. After four days acute malignant glaucoma was observed, with stage 3 athalamia requiring pars plana vitrectomy and secondary Ahmed valve implantation. The lower rate of complications due to minimally invasive glaucoma surgery has increased its use. Nevertheless, it is not free of severe adverse events, even requiring a multidisciplinary approach as in our malignant glaucoma report.
