RESUMO
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.

CLINICAL CASES: Cases are presented of 10 patients with Acanthamoeba keratitis treated between 2008 and 2017. All were contact lens wearers. All of them received treatment with a biguanide combined with a diamidine. In 3 cases the infestation did not exceed the superficial stroma, responding to topical treatment. In 7, the infection reached the deep stroma, with 6 of these cases requiring penetrating keratoplasty (PKP), 3 of them therapeutic PKP because of perforation risk or ocular spreading. The visual acuity improved in all the cases. CONCLUSION: The infestation depth at the time of diagnosis appears to be the main risk factor for requiring a PKP.
