Explanation

Glaucoma is damage to your optic nerve at the point where it leaves your eye. This type of damage affects your sight, and in kids it is usually caused by raised pressure in your eye.

The raised pressure can be caused by other problems affecting your eye, like inflammation, and this is called secondary glaucoma.

Glaucoma that happens really early in your life is called congenital glaucoma. Glaucoma is very rare in kids though.
