The condition and the treatment

The macula is the central part of the retina at the back of the eye. When a retinal vein becomes blocked (retinal vein occlusion) blood can leak into the macula causing it to swell. This is known as macular oedema and can affect sight. There are 2 types of blockage depending on which part of the vein is blocked: central or branch retinal vein occlusion.

Aflibercept (also known as Eylea) is given by injection into the eye. It works by blocking the substances that stimulate the growth of the abnormal blood vessels at the back of the eye.

NHS Choices (www.nhs.uk) may be a good place to find out more.
