Macular epiretinal membrane (MEM) treatment
Macular Epiretinal Membrane (MEM) Treatment
Surgery improves vision in 80% of cases.
Possibility of performing two procedures in one session: Vitrectomy + Cataract Surgery
What is MEM?
Macular Epiretinal Membrane (MEM) refers to the growth of tissue over the surface of the retina in the macular area, which can contract and cause vision loss and image distortion.
What Causes It?
It is caused by the deposition of certain cells over the macula, which usually come from the retina but can also originate from layers beneath the retina, such as the pigment epithelium. These cells secrete collagen, forming a mesh that can then apply traction to the collagen. Since this tissue is attached to the retina, when it contracts, the retina also contracts and warps.
How Can It Be Prevented?
These membranes are most commonly found in patients over the age of 50, but they can also occur at any age. They are sometimes a result of a retinal hole, which allows cells to pass through from beneath the retina. Therefore, it is crucial to see an ophthalmologist if symptoms like floaters or flashing lights appear, as these could indicate a retinal hole. Immediate treatment of retinal holes can prevent retinal detachment.
MEM can also appear after ocular surgery, so post-operative monitoring is extremely important.
Symptoms
The most common symptoms are:
- Vision loss
- Blurred vision
- Image distortion
Lines may appear distorted, and numbers and letters can seem misaligned.
Associated Treatments
It is important to monitor for retinal detachment through regular eye exams, especially after surgery, and see an ophthalmologist if any of the symptoms listed occur.
The most suitable treatment for MEM is Vitrectomy.
Vitrectomy
Vitrectomy is a surgical procedure where the vitreous humor is removed to reduce pressure and traction on the retina. This surgery can help improve vision in patients with Macular Epiretinal Membrane (MEM).
