Macular Oedema

Macular oedema is a build-up of fluid in the macula, the central part of the retina, causing blurred or distorted central vision.

Common symptoms

Blurred or wavy central vision, reduced reading vision, washed-out colours, and difficulty with fine detail.

Description

Macular oedema happens when fluid leaks from small blood vessels and collects within or beneath the macula, causing it to swell and function less well. It is a feature of several other eye conditions rather than a disease in its own right.

Common causes include diabetic eye disease, retinal vein occlusion, uveitis, and some types of macular degeneration. It can also occur after eye surgery.

Treatment focuses on the underlying cause and may include eye injections (anti-VEGF or steroid), laser treatment, or medication. Good blood sugar and blood pressure control are important when diabetes is involved.
