title: Retrieval of a mispositioned Ex-PRESS glaucoma device.
abstract: The purpose of this article was to report the misposition and subsequent retrieval of an Ex-PRESS (Optonol Ltd., Neve Ilan, Israel) glaucoma drainage device implanted in an eye with pseudoexfoliative glaucoma. The formation of excessive fibrosis at the site of the implant, which was partly dislocated into the anterior chamber, was observed. The Ex-PRESS drainage device was removed from the anterior chamber and the intraocular pressure was relieved through trabeculectomy at the superotemporal part of the globe. The results suggest that trabeculectomy is a practical approach to alleviate intraocular pressure in the case of failed glaucoma drainage devices.
