Summary

This study compares patient symptoms and anterior segment safety in patients treated with timolol hemihydrate, generic timolol gel forming solution or timolol maleate.

Eligibility Criteria

Inclusion Criteria

  • willing to comply with investigator's and protocol's instructions
  • 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
  • any concurrent infectious/noninfectious conjunctivitis, keratitis or uveitis in either eye
  • any history of allergic hypersensitivity or poor tolerance to any components of the preparations used in this trial
  • females of childbearing potential not using reliable means of birth control
  • pregnant or lactating females
  • any clinically significant, serious, or severe medical or psychiatric condition
  • participation (or current participation) in any investigational drug or device trial within 30 days prior to Visit 1
  • severe prior visual acuity or field loss from any cause
  • inability to understand the trial procedures, and thus inability to give informed consent
  • progressive retinal or optic nerve disease apart from glaucoma
  • serious systemic or ocular disease
  • intraocular laser surgery within the past three months or corneal or intraocular conventional surgery within the past 6 months
  • concurrent use of systemic corticosteroids, by IV, oral, dermal or topical ophthalmic route.
  • subjects requiring tear replacement drops or allergy medications with sympathomimetics 24 hours prior to a scheduled study visit
  • contraindication to beta-blocker usage including: reactive airway disease, uncontrolled heart failure, or second as well as third degree cardiac block, myasthenia gravis
  • any subject the investigator believes will be at risk for glaucomatous progression by their participation in this trial
