- patients signature on the informed consent document
- primary open-angle glaucoma, pigment dispersion or exfoliation glaucoma, or ocular hypertension in at least one eye
- at screening intraocular pressure must be considered to be safe, in both eyes
- in non-qualifying eyes the intraocular pressure should be able to be controlled safely on no pharmacologic therapy or on study medicine alone
- currently treated with one glaucoma medication, untreated intraocular pressure of less than or equal to 28 mm Hg at visit 2 in both eyes
Exclusion Criteria:
- any abnormality preventing reliable applanation tonometry in either eye
- any opacity or subject uncooperativeness that restricts adequate examination of the ocular fundus or anterior chamber in either eye
