Long-term experience with timolol ophthalmic solution in patients with open-angle glaucoma.

Area of Science:

• Ophthalmology
• Pharmacology

Background:

• Glaucoma is a leading cause of irreversible blindness.
• Effective long-term management of intraocular pressure (IOP) is crucial for preventing optic nerve damage.

Purpose of the Study:

• To evaluate the long-term efficacy and safety of timolol in glaucoma patients.
• To assess the sustained reduction in intraocular pressure with continuous timolol administration.

Main Methods:

• A cohort of 37 glaucoma patients were treated with timolol.
• Treatment duration ranged from 1 to 18 months.
• Adverse effects and intraocular pressure were monitored.

Main Results:

• Timolol produced sustained reductions in intraocular pressure.
• Continuous administration did not induce miosis or accommodative spasm.
• Mild slowing of resting pulse rate was observed due to systemic absorption.
• Ocular hypotensive effects were additive to miotics and carbonic anhydrase inhibitors in some patients.

Conclusions:

• Timolol is effective for sustained intraocular pressure reduction in glaucoma management.
• The drug is well-tolerated with minimal ocular and systemic side effects.
• Timolol offers an additive therapeutic option for complex glaucoma cases.
