Epiretinal membrane

La Epiretinal membrane is the growth of a translucent tissue on the retina, more specifically in the macula. When this tissue wrinkles causes vision distortion. The macula is the part of the reitin that is responsible for the central vision and the perception of the details.

Now macular epiretinal membrane (MEM) is also known by the name of premacular fibrosis, cellophane membrane o epimacular membrane.

La Epiretinal membrane is the growth of a translucent tissue on the retina, more specifically in the macula. When this tissue wrinkles causes vision distortion. The macula is the part of the reitin that is responsible for the central vision and the perception of the details.

What is the epiretinal membrane?

The epiretinal membrane is an ocular pathology that occurs when a translucent cell membrane develops over the central area of ​​the retina, the macula. The macula is the part where photoreceptors are located, the cells designed to transform the information received by the eye into images that reach the brain.

When the translucent membrane that we mentioned previously develops, and it contracts and wrinkles, it produces a progressive deformation of the retina that alters vision.

The epiretinal membrane, also known as premacular fibrosis, cellophane membrane o epimacular membrane, is present in approximately 2% of patients over 50 years and this percentage increases up to 20% among the population over 75 years.

Causes of the epiretinal membrane

The main cause that explains the development of the epiretinal membrane is age. It can be suffered from the 50s, especially in the case of women, and it can be bilateral, that is, affect both eyes.

Can also be formed after surgery or eye inflammation as well as vascular diseases, such as diabetes.

phosphenes

symptom

In some cases, they can remain completely asymptomatic. When the epiretinal membranes progress they can induce the increased thickness and the appearance of folds or wrinkles on the retina, which manifest as distortion of central vision or progressive decrease in visual acuity.

In these cases, surgical treatment is indicated by posterior vitrectomy and removal of the membrane.

How to know if I have an epiretinal membrane

At the beginning, when it is being developed, no change is noticed. However, once growth has stopped, it causes a central vision distortionIe the lines are observed crookedly.

Diagnosis

We currently have the OCT (optical coherence tomography) as main test, AGT (fluorescein angiography) and autofluorescence. OCT allows us to observe with great precision the state of the macula and if the membrane is producing an alteration on the anatomy of the same.

Treatment of the epiretinal membrane

El only possible treatment is by a surgical procedure called vitrectomy. During the operation the vitreous is removed from inside the eye. Then, the membrane is removed and, depending on the case, sutures are placed that are reabsorbed after one month.

The surgery is done depending on the degree of vision of the patient and it must be determined by an ophthalmologist. Not all patients with epiretinal membrane are able to undergo surgery.

Finally, it should be noted that if this pathology is not treated in time you can suffer a significant loss of central vision and, although it does not cause blindness, it must be corrected as soon as possible to reverse the process.

Forecast and result

Early diagnosis and treatment prevents progressive decline in vision, and can correct image distortion and improve visual acuity. it's possible combine removal of epiretinal membranes to cataract surgery in the same surgical act. In untreated progressive cases, a permanent irreversible decrease in visual acuity may occur.

When the Epiretinal Membrane contracts it causes distortion of the retinal tissue. If that happens, the macula does not function normally.
