What is Macular oedema?

Macular oedema is an ophthalmological disorder characterised by the macular inflammation of the eye, a small area located in the centre of the retina that is responsible for focusing on images and perceiving the fine details of your eyesight.

This disorder occurs when the blood vessels that irrigate the retina become altered, extremely permeable and/or leak, and through which fluids accumulated in the macula are filtered. As a result, it becomes inflamed and cannot work properly.


Macular oedema is painless and you might not notice it in its initial phase. As it progresses, symptoms include blurred central vision and distorted images (alterations in the shape of surrounding objects, deformed facial features, broken or twisted lines, etc.) and changes in the perception of colours. These symptoms are characteristic of damage to the macula and may hinder everyday activities such as reading, writing or other tasks requiring precision.
