We are the charity beating the fear and isolation of macular disease with world-class research, and the best advice and support.
About macular disease
The macula is part of the retina at the back of the eye. It is only about 5mm across but is responsible for our central vision, most of our colour vision and the fine detail of what we see.
What is the macula?
About macular disease
The macula is part of the retina at the back of the eye. It is only about 5mm across, but is responsible for our central vision, most of our colour vision and the fine detail of what we see. A healthy macula is about 250 microns (one quarter of a millimetre) thick.
Diabetic macular oedema (DMO)
Diabetic Macular Oedema (DMO) is a vision threatening complication of diabetes, macular oedema can also occur due to inflammation, retinal vein occlusion, surgery and other reasons, to understand more about these other causes visit our Macular oedema webpage.
Age-related macular degeneration
Age-related macular degeneration (AMD) usually affects people over 50 but can happen earlier. Macular disease is the biggest cause of sight loss in the UK, with AMD affecting around 700,000 people.
Wet age-related macular degeneration (AMD)
Wet age-related macular degeneration (AMD) develops when abnormal blood vessels grow into the macula. These leak blood or fluid which leads to scarring of the macula and rapid loss of central vision. Wet AMD can develop very suddenly, but it can now be treated if caught quickly. Fast referral to a hospital specialist is essential.
Early age-related macular degeneration (AMD)
All parts of the body change as we age and it's normal to see differences in the way the retina looks in older people. There may be changes to the colour of the retina, and tiny, fatty deposits called drusen may appear.
Retinal vein occlusion (RVO)
Retinal vein occlusion (RVO) is a blockage of a retinal vein. It is a common cause of sudden painless reduction in vision in people over 60. The blockage of a vein causes blood and other fluids to leak into the retina, which causes damage that reduces vision.
The retina is a light-sensitive layer of tissue lining the back of the eye. The macula is a small area at the centre of the retina responsible for all of our central vision, most of our colour vision, and the fine detail we see.
Myopic macular degeneration
Myopia, pathological myopia and myopic macular degeneration
Myopic macular degeneration is a type of macular degeneration that occurs in people with severe myopia.
