What Is Myopic Macular Degeneration (Mmd)?

What is myopic macular degeneration (MMD)?

Myopic macular degeneration (MMD) is damage to the macula that occurs in pathological myopia. Pathological myopia is due to progressive, abnormal elongation of the eyeball. This results in degenerative changes to the back of the eye. Myopic macular degeneration can lead to irreversible vision loss.

What are the symptoms of myopic macular degeneration?

The macula is located in the central part of the retina. It provides our sharpest central vision. Damage to the macula can cause individuals to experience symptoms such as:

Myopic maculopathy is a leading cause of vision impairment worldwide. It can result in permanent vision impairment and blindness. A recent study found that adults with high myopia and myopic macular degeneration may experience visual field loss as well. 

Myopic macular degeneration occurs in pathological myopia. This is myopia that is associated with degenerative changes in the back of the eye. These changes are due to elongation of the eyeball, which leads to overstretching and thinning of the retina, choroid and sclera.

Other degenerative changes to the back of the eye also occur with MMD. These include an increased risk of retinal detachment, retinal tears and posterior vitreous detachment. If a sudden onset of floaters or flashing lights or a dark curtain over your vision is noticed, contact a doctor immediately. This may be a sign of a retinal detachment and is an emergency condition.
