Primary Outcome Measures
NameTimeMethod
Percentage of Eyes With IOP Lowering Rate of 20% or More From Baseline up to Month 12Baseline (Pre-Operative), Month 3, Month 6, Month 12 Post-Operative

IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and reported in mmHg. A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage). Only one eye contributed to the analysis.

Percent Change From Baseline in IOPBaseline (Pre-Operative), Month 3, Month 6, Month 12 Post-Operative

IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and reported in mmHg. A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage). A more negative percent change from baseline indicates a greater improvement, i.e., a reduction of IOP. Only one eye contributed to the analysis.

Change From Baseline in IOPBaseline (Pre-Operative), Month 3, Month 6, Month 12 Post-Operative

IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and reported in mmHg. A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage). A more negative change from baseline indicates a greater improvement, i.e., a reduction of IOP. Only one eye contributed to the analysis.

Percentage of Eyes Receiving Secondary Surgical Treatment (Including Laser Therapy) Necessary to Maintain the IOPMonth 3, Month 6, Month 12 Post-Operative

IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and reported in mmHg. A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage). Secondary surgical treatment included needling, laser suture lysis, and conjunctival and scleral flap sutures. For some subjects, both left and right eyes were targeted for the study, and data from both eyes were analyzed for this safety endpoint, as specified in the protocol. An eye may have received more than one procedure.

Mean Intraocular Pressure (IOP)Month 3, Month 6, Month 12 Post-Operative

IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and reported in mmHg. A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage). Only one eye contributed to the analysis.

Percentage of Eyes Receiving Drug Therapy for Glaucoma Necessary to Maintain the IOPMonth 3, Month 6, Month 12 Post-Operative

IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and reported in mmHg. A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage). For some subjects, both left and right eyes were targeted for the study, and data from both eyes were analyzed for this safety endpoint, as specified in the protocol.
