Living with Melanoma associated retinopathy

A rare immune condition in some people with melanoma that harms the retina and affects vision.

Understanding Melanoma associated retinopathy

Melanoma-associated retinopathy (MAR) is a rare autoimmune condition that can occur in some people with melanoma and can affect vision.

In MAR, the immune system responds to melanoma (a skin cancer) and mistakenly attacks cells of the retina, the light-sensing layer at the back of the eye. GARD says it is poorly understood why this happens in some people and not others.

Signs & symptoms

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

  • Night blindness
  • Seeing flashes of light (photopsia)
  • Vision loss that gets worse and is painless

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.

Care & treatment

Everyday life

Living with a rare condition is easier with support.

  • Connect with Melanoma Research Alliance
  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
