Clinical Trial Outcome Measures

    • Time Frame: 3 weeks

Participating in This Clinical Trial

Inclusion Criteria

  • 18 years of age or greater
  • Diagnosis of open angle glaucoma or ocular hypertension in both eyes
  • Corrected visual acuity in each eye +1.0 logMAR or better by Early Treatment Diabetic Retinopathy Study (EDTRS) in each eye (equivalent to 20/200)

  • Glaucoma: pseudoexfoliation, steroid induced, pigment dispersion glaucoma, and or history of angle closure. Previous glaucoma intraocular surgery or glaucoma laser procedures in study eye(s). Refractive surgery in study eye
  • Cataract surgery and or other intraocular surgery within one month prior to Screening in either eye
  • History within 3 months prior to Screening of clinically significant moderate or severe chronic or active ocular infection, inflammation, blepharitis, dermatitis, uveitis or conjunctivitis
  • Clinically significant corneal dystrophy, epithelial and or endothelial disease, corneal irregularities and or scarring such that reliable applanation tonometry would prevented
