What is primary congenital glaucoma (PCG)?

ANSWER

It’s a type of glaucoma, a group of diseases in which high fluid pressure in your eye damages the optic nerve. It affects children between birth and 3 years.

Primary congenital glaucoma (PCG) is a serious condition that needs attention. It affects about one in every 10,000 infants. Untreated cases are a major cause of childhood blindness.

"Primary" means the disease doesn’t result from another illness or condition, like a tumor. "Congenital" means it’s present at birth.
