Trial Outcomes & Findings for Alcon® Ex-PRESS® Glaucoma Filtration Device in Japanese Patients (NCT NCT02246777)

NCT ID: NCT02246777

Last Updated: 2018-07-20

Results Overview

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.

Population: Intent-to-Treat, with non-missing data

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.

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.

Population: Intent-to-Treat Analysis Set with non-missing data

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.

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.
