Distribution of IOP-lowering eyedrops used to treat glaucoma.
Notes: Timolol maleate, a beta-adrenergic blocker, was the commonest IOP-lowering topical eyedrop used in these patients, followed by prostaglandin analogs and alpha-adrenergic blockers. In comparison, combination therapy and carbonic anhydrase inhibitors were used much less frequently in these patients.
Abbreviations: IOP, intraocular pressure; CA, carbonic anhydrase.
