Age-related macular degeneration (ARMD) is a significant cause of profound vision loss in the Australian community, particularly among older Australians. Onset of ARMD is typically over 50 years of age, with the risk then progressively increasing with age.
This degenerative condition affects the macula, a small area at the centre of the retina. The macula is responsible for fine detailed vision, required for activities such as driving, reading and distinguishing colour. ARMD affects a person's central vision, including both distance and near vision, and can lead to partial vision loss or blind-spot areas in the centre. The side (or peripheral) vision remains intact.
ARMD exists in two clinical forms: atrophic (dry) and exudative (wet). Current treatment options for dry ARMD are through vitamin supplementation and diet modification. Wet ARMD is managed using intraocular injection of anti-VEGF pharmaceutical agents. Early diagnosis and timely intervention are vital to preserving vision in ARMD.
Functional implications of ARMD include:
People with ARMD may be able to move around safely and with minimal difficulty, and locate items with their peripheral vision.
