Living with Coats plus syndrome

An inherited condition with a retina disease called Coats disease, plus changes in the brain, bones, and digestive system.

Understanding Coats plus syndrome

Coats plus syndrome is an inherited condition with Coats disease of the eye plus differences in the brain, bones, gut, and other parts of the body.

In Coats disease, blood vessels in the retina are widened and twisted, leak fluid, and can cause retinal detachment and vision loss. People also have brain changes such as calcium deposits, cysts, and loss of white matter (leukodystrophy) that worsen over time. These can cause slow growth, movement problems, seizures, and a decline in thinking skills. Low bone density makes bones fragile. GARD lists onset in childhood.

Signs & symptoms

GARD doesn't list specific symptoms for this condition, but the summary describes:

  • Leaky, twisted blood vessels in the retina
  • Vision loss
  • Calcium deposits and cysts in the brain
  • Movement problems and seizures
  • Slow growth
  • Weak, easily broken bones

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