Purpose: To determine the effectiveness of the Ex-Press mini glaucoma shunt. Methods: We implanted the new device for treatment of glaucoma in ten patients, following the standard surgical procedure. Results: After a three months follow-up, two patients mantained safe intraocular pressure range without complications. The rest showed a high variability of pressure and a diversity of complications such as fibrosis and athalamia Purpose: To determine the effectiveness of the Ex-Press mini glaucoma shunt.
