Glaucoma medications: use and safety in the elderly population

Area of Science:

• Ophthalmology
• Geriatric Medicine
• Pharmacology

Background:

• Glaucoma is an age-related optic neuropathy, often seen in patients with multiple comorbidities and medications.
• Intraocular pressure (IOP) is a primary factor in glaucomatous optic neuropathy (GON), and its reduction is the only established effective treatment.
• The increasing use of glaucoma medications in older populations necessitates a closer look at potential systemic complications.

Purpose of the Study:

• To highlight the challenges in managing glaucoma in older adults, particularly concerning polypharmacy.
• To emphasize the importance of considering systemic side effects of topical glaucoma medications, which can be overlooked.
• To explore glaucoma as a model for neurodegenerative diseases and investigate neuroprotective strategies.

Main Methods:

• Review of current understanding of glaucoma pathophysiology and treatment.
• Analysis of the role of intraocular pressure (IOP) in disease progression.
• Discussion of potential systemic adverse effects of glaucoma pharmacotherapies.

Main Results:

• Glaucoma prevalence increases with age, frequently co-occurring with other medical conditions and medication use.
• Reducing IOP is the cornerstone of glaucoma management, slowing disease progression.
• Systemic complications from topical glaucoma medications may be underrecognized in elderly patients.

Conclusions:

• Effective glaucoma management in older adults requires careful consideration of IOP reduction and potential systemic drug effects.
• Further research is needed to fully understand and mitigate systemic complications associated with glaucoma pharmacotherapy.
• Glaucoma research can inform strategies for other neurodegenerative conditions, including neuroprotection and excitotoxicity.
