Glaucoma

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.

What are the symptoms of pediatric glaucoma?

Some of the most common symptoms of childhood glaucoma that our Nemours pediatric ophthalmologists look for are:

  • excessive tearing
  • sensitivity to light
  • a dull-looking iris caused by clouding of the cornea

A to Z: Otorrhea

Otorrhea is discharge from the external part of the ear canal.

More to Know

Ear drainage can be serous (thin and watery), sanguineous (containing blood), or purulent (full of pus). It may or may not smell foul.

Vertigo, ear pain, fever, itching, ringing in the ear, and hearing loss are all symptoms that can accompany otorrhea.

Many things can cause fluid to drain from the ear. Most commonly, it occurs with swimmer's ear or when an ear infection leads to a perforated eardrum (with or without middle ear infection). Head injury can cause leaking of cerebrospinal fluid (the fluid that surrounds the brain and spinal cord). Head injury is a less common cause of otorrhea, but it is more serious and can be life threatening.

Keep in Mind

Because ear discharge has many origins, it's important to see a doctor to identify the cause so that it can be properly treated.
