Living with Morning glory syndrome

A birth difference of the eye's optic nerve, with a funnel-shaped nerve head and often poor vision in the affected eye.

Understanding Morning glory syndrome

Morning glory syndrome is a birth difference of the optic nerve that looks like a morning glory flower.

The optic disc, where nerve fibers leave the retina, is enlarged and funnel-shaped with a white center. Blood vessels are increased in number and curve outward like flower petals. Most cases affect one eye and cause very poor vision in that eye. It can occur alone or with other eye differences, such as crossed eyes and lazy eye. Retinal detachment is the most severe complication and occurs in about 26 to 38 percent of people.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Very poor vision in the affected eye
  • Funnel-shaped optic nerve head
  • Eyes that turn (strabismus)
  • Lazy eye (amblyopia)
  • Changes in retina pigment

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.

Care & treatment

Everyday life

Living with a rare condition is easier with support.

  • Connect with rare disease patient organizations for support
  • 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
Bring these questions to your next doctor visit
How often should the retina be checked for detachment?
What can be done to protect vision in the other eye?
Should we check for other related problems, such as in the brain?

Quick facts

Symptoms usually startChild

GARD says it seems to be caused by the optic nerve not forming completely while the baby develops. Changes in genes (also called variants) are listed as a cause, but GARD does not name a gene.
