NCT ID: NCT02691455

Last Updated: 2021-11-02

Results Overview

Treatment failure is defined as meeting one or more of the following 4 criteria: 1. Intraocular pressure (IOP) a) \>18 mm Hg on maximum tolerated topical IOP-lowering medications, or b) Reduction of \< 20% IOP on maximum tolerated topical IOP-lowering medications from medicated preoperative IOP, or c) ≤ 5 mm Hg without IOP-lowering medications on IOP confirmation visit, 6 months after initial study intervention; or 2. Reoperation for glaucoma; or 3. Addition of an oral CAI for the study eye on or after the 6-Month Study Visit; or 4. Loss of light perception vision (NLP).
