Mini-drainage devices: the Ex-PRESS Mini-Glaucoma Device.

The Ex-PRESS Mini-Glaucoma Device is a glaucoma drainage device used to shunt aqueous from the anterior chamber into a subconjunctival reservoir that is created surgically. It has been used successfully over the last decade with approximately 60,000 implantations worldwide. In an ever-evolving microsurgical environment, the Ex-PRESS glaucoma device is on the forefront of intraocular pressure lowering technology. This chapter aims to review the surgical uses, techniques and considerations of the Ex-PRESS device as well as analyze the current literature detailing the advantages and disadvantages of the Ex-PRESS implant. Special attention will also be placed on the authors' own experience using the device.
