Build-up of fluid in the macula

What is macular oedema?

The macula is the part of the retina with the greatest visual acuity, i.e., it is the area where the image lands when we look at an object and is therefore what enables us to appreciate our surroundings with maximum clarity.

Macular oedema is a build-up of fluid in the macula, altering the structure of the retina. It therefore leads to a reduction in visual acuity, especially in the central area, and in the ability to see in detail.

One of the most significant causes of macular oedema is diabetes.

Diabetic retinopathy

Age-related macular degeneration (AMD)

Inflammatory disorders

Select one of the following frequently-asked questions from our patients to show the answer. If you cannot find the answer to your question, please contact us using the form below.

Can I lose my vision as a result of macular oedema?

Yes, the build-up of fluid at the retina changes the normal functioning of the retinal nerve cells, preventing them from receiving and transmitting light signals properly.

Can vision loss be recovered?

Depending on the cause and whether the oedema has appeared recently, full visual acuity can often be recovered with the right treatment.

Why does it reappear after stopping treatment?

Macular oedema is, at the end of the day, a sign indicating retinal abnormality, which can be due to multiple causes. If the underlying disorder is chronic by nature, such as diabetes or macular degeneration, the oedema may reappear when treatment is stopped.

Is it a bad thing for it to be treated many times?

Treatment needs to be adjusted to each individual case. If we improve the patient’s visual acuity with treatment, the benefits outweigh the risks, which are usually negligible, and retreatment where necessary is not harmful.
