Epiretinal Membrane (ERM)
An epiretinal membrane (ERM) is an eye condition where a thin, clear, and transparent fibrous cellular material forms on the surface of the retina. It commonly occurs, affecting the posterior pole of the retina over the macula. The cause is unknown, but some research shows that it can be secondary to trauma, post-intraocular surgery, chronic ocular diseases, and so on.
Symptoms:
ERMs usually cause several symptoms, such as:
Difficulty in seeing fine details and recognizing faces when the central part of the retina is affected.
Blurred and distorted vision.
Straight lines appear wavy.
Decreased vision and loss of central vision.
Double vision.
Causes:
Epiretinal membranes can occur as a result of the normal aging process in the eyes. It is common in individuals over the age of 50. One reason for this condition is when the vitreous gel peels away from the retina. ERM may also form following retinal or eye surgery.
Diagnosis:
An epiretinal membrane can be diagnosed during a routine eye examination for mild cases where the symptoms do not affect the individual. During the eye examination, an optometrist or ophthalmologist may use a non-invasive imaging technique called Optical Coherence Tomography (OCT) to visualize the layers of the retina. In some patients, an ophthalmologist will request additional tests such as fluorescein angiography to determine any other underlying problem that might have caused this problem. The test involves the use of dye to light up areas in the retina.
Treatment:
In many cases, mild membranes are monitored over time for progression. Aside from surgery, there are no other available treatments for epiretinal membranes. Eyeglasses, contact lenses, and prescription eye drops are generally not effective treatments for epiretinal membrane.
Therefore, it is advisable to visit for a detailed eye examination if you experience any unusual symptoms related to an epiretinal membrane (ERM). Moreover, an eye screening can also be beneficial for the early detection of any retinal disorder.
