Pediatric glaucoma is a rare condition characterized by damage to the optic nerve and usually caused by elevated internal eye pressure (or "intraocular pressure"). The optic nerve is responsible for sending vision from the eye to the brain.
Infantile or congenital glaucoma may be present from birth and is caused by problems in the development of the eye’s drainage system. The elevation in intraocular pressure that results can damage the optic nerve and cause severe vision loss. Juvenile glaucoma occurs in children older than age three and is caused by other problems that can lead to increased eye pressure.
