Spontaneous extrusion of a stainless steel glaucoma drainage implant (Ex-PRESS).

摘要

PURPOSE: To report a case of spontaneous extrusion of a stainless steel glaucoma drainage implant (Ex-PRESS). METHODS: An Ex-PRESS was implanted under the conjunctiva in a 76-year-old man with primary open-angle glaucoma. RESULTS: Two years after implantation, the Ex-Press extruded spontaneously. Despite this adverse event, there was no increase in intraocular pressure. CONCLUSIONS: This is the first report of spontaneous extrusion of an Ex-PRESS device. Implanting the device under a scleral flap should be considered to avoid adverse events such as extrusion or conjunctival erosion.
