Macular degeneration is a condition affecting the macula, the central part of the retina responsible for sharp, detailed vision. It commonly occurs in people over the age of 65 and can cause blurred or distorted central vision, with straight lines appearing wavy or a dark patch developing in the centre of sight. Peripheral (side) vision is usually preserved.

There are two types: dry and wet macular degeneration. Dry macular degeneration develops slowly and currently has no treatment, although regular monitoring is advised. Wet macular degeneration can cause rapid vision loss but can be treated with anti-VEGF eye injections to slow progression and reduce further damage. Early diagnosis and treatment are important to protect vision.
