Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria

2. Glaucoma hemi-field test "outside normal limits."
5. Glaucomatous optic nerve damage as evidenced by any of the following optic disc or retinal nerve fiber layer structural abnormalities:
1. Diffuse thinning, focal narrowing, or notching of the optic disc rim, especially at the inferior or superior poles with or without disc hemorrhage;
2. Localized abnormalities of the peripapillary retinal nerve fiber layer, especially at the inferior or superior poles; or
