          -  Intraocular surgery within the past 3 months.

          -  Best-corrected visual acuity score worse than 55 ETDRS letters read (equivalent to
             approximately 20/80 Snellen, 0.60 logMAR or 0.25 decimal).

          -  History of, or current clinically relevant or progressive retinal disease in either
             eye.

          -  History of, or current other severe ocular pathology (including severe dry eye) in
             either eye, that would preclude the administration of a topical carbonic anhydrase
             inhibitor (CAI) or beta-blocker.

          -  Any abnormality preventing reliable applanation tonometry.

          -  History of, or current condition or disease that would preclude the safe
             administration of a topical beta blocker or topical beta-adrenergic blocking agent.

          -  History of spontaneous or current hypoglycemia or uncontrolled diabetes.

          -  History of severe or serious hypersensitivity to CAIs, beta-blockers, or to any
             components of the study medication.

             affected IOP.

          -  Recent use of high-dose salicylate therapy.
