Living with Coloboma of macula

A rare genetic eye condition where a small area of the retina's center did not form fully, lowering vision.

Understanding Coloboma of macula

Coloboma of macula is a rare eye condition in which the center of the retina did not form fully before birth.

It causes well-defined, oval or round areas where the retina, choroid and sclera are thin or missing at the macula, usually in one eye. This leads to decreased vision and sometimes other symptoms such as strabismus. It is usually isolated but may be linked to Down syndrome, skeletal or kidney conditions.

Signs & symptoms

Symptoms vary from person to person. GARD describes these features:

  • Decreased vision
  • Eyes that do not line up (strabismus)
  • Usually affects one eye

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

    Specialists who may be involved include eye disease specialists and genetic specialists.

  3. Ask which tests can help

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