Cohort 1 Experimental

ENV515-1 and ENV515-3 implants in Study Eye for 28 days

Cohort 2 Experimental

Two ENV515-3 implants in Study Eye for 12 months with optional 6 month and 3 month extensions (total of 21 months)

Criteria

Inclusion Criteria:

Diagnosis of either ocular hypertension or open angle glaucoma in both eyes.
Are currently treated with topical PGA for ocular hypertension in both eyes.
Patients who in the opinion of the Investigator: have an IOP in both eyes that is considered to be adequately controlled, can be safely withdrawn from IOP medications in both eyes during the washout period, and who are not considered to be at significant risk for disease progression throughout the trial.

Exclusion Criteria:

Eye surgery (including cataract surgery) within the past 3 months.
History of glaucoma related surgery.

Summary of Change From Baseline Average Intraocular Pressure Diurnal Measurement by Treatment Group Population (Cohort 1)

Average intraocular pressure (IOP) diurnal measurement is calculated by taking the average of the intraocular pressure measurements at 8AM, 10AM and 4PM. The protocol was later amended (Amendment 09) to a safety only study so the diurnal measurements were no longer collected for Cohorts 2 and 3; only the 8AM IOP was collected as a safety assessment only.
