Eligibility

Inclusion criteria

Inclusion criteria: 1. Male or non-pregnant female aged at least 18 years with chronic open angle glaucoma or ocular hypertension in both eyes. 2. Subject requires treatment of both eyes and is able to discontinue the use of all ocular hypotensive medication(s) or switch ocular hypotensive medications and undergo appropriate washout period. 3. Baseline (Day 0/hour 0) IOP = 22 mm Hg and = 34 mm Hg in each eye and any asymmetry of IOP between the eyes no greater than 5 mm Hg. 4. Subject has the best spectacle-corrected visual acuity (BSCVA) equivalent to 20/200 or better in each eye. 5. Adequate wash-out period prior to the baseline of any ocular hypotensive medication. To minimize potential risk to the subject due to intraocular pressure (IOP) elevations during the washout period, the investigator may choose to substitute a parasympathomimetic or carbonic anhydrase inhibitor in place of a sympathomimetic, alpha-agonist, beta-adrenergic blocking agent, or prostaglandins; however, the subject must have discontinued all ocular hypotensive medication for the minimum washout period provided in the table below; Medication Minimum Washout Period Parasympathomimetics (e.g., pilocarpine, carbachol) 4 days Carbonic anhydrase inhibitors (systemic or topical) (e.g., acetazolamide, dorzolamide hydrochloride, and brinzolamide) 4 days Sympathomimetics (e.g., dipivefrin, and epinephrine) 2 weeks (14 days) Alpha-agonists (e.g., apraclonidine, brimonidine tartrate, brimonidine tartrate/brinzolamide) 2 weeks (14 days) Beta-adrenergic blocking agents (e.g., timolol, timolol maleate, dorzolamide hydrochloride, timolol maleate and brimonidine tartrate, levobunolol, betaxolol, metipranolol, carteolol) 4 weeks (28 days) Prostaglandin analogs (e.g., latanoprost, travoprost, bimatoprost, and tafluprost) 4 weeks (28 days) 6. Subject are willing and able to provide written informed consent before any study procedures are performed. 7. Subject willing and able to understand and comply with the requirements of the study, consume the Investigational Product as instructed, return at the appropriate scheduled visits, comply with therapy prohibitions, and be able to complete the study. 8. Female subject of childbearing potential practicing an approved method of contraception and willing to continue its use from study entry to the end of the study and have a negative Urine Pregnancy Test at the time of screening or Female subject of non-childbearing potential. 9. Male subjects must use accepted methods of birth control or must agree to practice abstinence from study entry to the end of the study

Exclusion criteria

Exclusion criteria: 1. Subject with angle closure glaucoma. 2. Females who are pregnant, breastfeeding, or planning a pregnancy. 3. Female of childbearing potential who do not agree to utilize an adequate form of contraception. 4. Current or past history of severe hepatic or renal impairment. 5. Current or history within 2 months before baseline of significant ocular disease, e.g., corneal edema, uveitis, ocular infection, or ocular trauma in either eye. 6. Current corneal abnormalities that would prevent accurate IOP readings with the Goldmann applanation tonometer. 7. Patients with severe central visual field loss in either eye; severe central visual field loss was defined as a sensitivity of less than or equal to 10dB in at least 2 of the 4 visual field test points closest to the point of fixation. 8. Corneal thickness more than600 µm in either eye. 9. History of severe dry eye in either eye. 10. Subjects with known or suspected drug or alcohol abuse. 11. Contraindication to brinzolamide or sulfonamide therapy or known hypersensitivity to any component of brinzolamide or sulfonamide therapy. 12. Use at any time before the baseline of intraocular corticosteroid implant. 13. Use within 1 week before the baseline of contact lens. 14. Use within two weeks before baseline of 1) topical ophthalmic corticosteroid or 2) topical corticosteroid. 15. Use within one month before baseline of 1) systemic corticosteroid or 2) high-dose salicylate therapy. 16. Use within six months before baseline of intravitreal or subtenon injection of ophthalmic corticosteroid. 17. Having undergone within 6 months before baseline any other intraocular surgery (e.g., cataract surgery, LASIK). 18. Having undergone within 12 months before baseline refractive surgery, filtering surgery, or laser surgery for IOP reduction. 19. Participating in a clinical study or therapy with an Investigational Product within the past 30 days.
