    A dislocated lens in the eye is often the first sign of Marfan syndrome. Because of this, an ophthalmologist can play an important role in diagnosing the disorder.

    A slit-lamp eye exam will determine if you have dislocated lenses. Using this special microscope, your ophthalmologist can examine your eye in detail. This makes it easier to spot abnormalities.

    Your ophthalmologist will refer you to other doctors if he or she suspects Marfan syndrome. They will conduct further tests to determine if you have the syndrome. This includes heart tests. Doctors diagnose it using a list of features found in Marfan syndrome.

    Marfan syndrome treatment

    Marfan syndrome can cause several different eye disorders. You should see an ophthalmologist regularly. Your ophthalmologist can treat many of the eye problems associated with Marfan syndrome.

    Dislocated lenses

    He or she can correct vision problems caused by dislocated lenses. Special glasses and eye drops that make your pupil larger can improve your vision. Sometimes dislocated lenses may need to be removed if they are interfering with vision.


    Having Marfan syndrome also puts you at higher risk for several eye diseases. You may develop cataracts at a younger age. If cataracts do develop, cataract surgery can improve your vision.


    You are also at higher risk for developing glaucoma. Several glaucoma treatment options are available.

    Lazy eye

    Children diagnosed with Marfan syndrome can also develop amblyopia (lazy eye). It is important that treatment starts early for sight to be recovered in the weaker eye.

    Retinal detachment

    Marfan syndrome puts you at higher risk for having a retinal detachment. Be aware of the symptoms of retinal detachment. Seek immediate help from your ophthalmologist if you have any of the signs of a detached retina.

    Signs of retinal detachment include a sudden onset of:

    • floaters (small specks, dots, circles, lines or cobwebs in the field of vision)
    • flashes (flashing lights or lightning streaks in the field of vision)
    • dark shadows in your peripheral (side) vision
