Age-related macular degeneration: Updates for general practitioners

Area of Science:

• Ophthalmology
• Geriatrics

Background:

• Age-related macular degeneration (AMD) is the primary cause of irreversible vision loss in Australians over 50.
• AMD progresses through stages, leading to conditions like neovascular ('wet') or atrophic ('dry') AMD.
• Key risk factors include age, family history, smoking, diet, and cardiovascular disease.

Purpose of the Study:

• To enhance awareness of AMD within general practice.
• To guide general practitioners (GPs) in early AMD detection and prevention strategies.
• To address the needs of an aging population at risk for AMD.

Main Methods:

• GPs performing macular examinations in at-risk individuals.
• Promoting smoking cessation and Mediterranean-style diets.
• Recommending Age-Related Eye Disease Study 2 (AREDS2) supplements for intermediate AMD.
• Urgent ophthalmology referral for sudden vision changes suggestive of wet AMD.

Main Results:

• Early detection and intervention are crucial for managing AMD.
• Lifestyle modifications and supplementation can impact AMD progression.
• Prompt referral is vital for potential neovascular AMD cases.

Conclusions:

• GPs play a vital role in AMD management through screening and preventative advice.
• Current treatments for wet AMD involve anti-VEGF therapy.
• Emerging therapies like complement inhibitors and gene therapy show promise for dry AMD and geographic atrophy.
