Earlier Intraocular Pressure Control After Ahmed Glaucoma Valve Implantation for Glaucoma

Completed · Phase 4

Conditions studied: Glaucoma

In brief

The purpose of this study is to compare the occurrence rate of the high pressure phase and the final pressure outcomes between patients treated with glaucoma medication prior to the expected onset of the high pressure phase to those patients who have glaucoma medication started at the onset of the high pressure phase. The investigators hypothesize that if glaucoma medications are started prior to the expected onset of high pressure phase, the high pressure phase will not occur as frequently and the ultimate pressure level will be lower than if the glaucoma medications are started at the onset of this phase.
