Living with Vitelliform macular dystrophy

A genetic eye condition that affects the center of the retina and can slowly blur central vision.

Understanding Vitelliform macular dystrophy

Vitelliform macular dystrophy is a genetic eye disorder that can cause vision loss that worsens over time.

It affects the macula, a small area near the center of the retina that gives sharp central vision for reading, driving, and recognizing faces. A fatty yellow pigment builds up under the macula. Side vision and night vision are typically not affected. The early-onset form (Best disease) usually appears in childhood. The adult-onset form usually begins in mid-adulthood.

Signs & symptoms

GARD doesn't list a common-symptom list, but its summary describes these:

  • Blurry central vision
  • Distorted vision
  • Slow loss of central vision

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

Quick facts

GARD explains that a yellow pigment (lipofuscin) builds up in cells under the macula and can damage them. It doesn't list a gene or inheritance pattern here.
