[Mode of action, clinical profile and significance of beta-blockers in antiglaucoma therapy].

Beta-blockers are among the most important groups of drugs for glaucoma therapy. The advantages of beta-blockers are a good efficacy in primary and secondary types of glaucoma, different dosages, clinical experiences over decades, easy use in combination with all other glaucoma drugs, and low costs. Timolol is the most frequently used drug in fixed glaucoma medications. In comparison with other glaucoma drugs, beta-blockers have the most severe systemic side effects and may interact with other systemic medication.
