Glaucoma (for Parents) – KidsHealth

What Is Glaucoma?

Glaucoma is a condition that damages the eye’s
optic nerve. It gets worse over time and leads to vision loss if not treated. The
damage from glaucoma often is linked to a buildup of pressure inside the eye.

Regular eye exams can help doctors find glaucoma
(glau-KOH-muh) early and start treatment right away.

What Happens in Glaucoma?

Normally, a healthy eye makes clear fluid that slowly drains from the eye.

In a person with glaucoma, the eye usually either makes too much fluid too fast
or the fluid drains away too slowly. This typically causes the pressure in the eye
to increase, which can lead to optic nerve damage and vision problems.

What Problems Can Happen?

Glaucoma can make it hard for a person to see or cause total blindness. That’s
because the optic nerve is the main nerve that carries signals from the eye to the
brain, allowing us to see.

If a person loses their vision due to glaucoma, their vision doesn’t come back,
even if the eye pressure goes back to normal.

When kids have glaucoma, vision loss usually happens more quickly and is often
more severe than when adults have glaucoma.

What Are the Signs & Symptoms of Glaucoma?

Doctors may notice symptoms at birth. But glaucoma doesn’t always show up right
away. Children can develop it as they grow.

When pressure builds inside the eye, it can lead to glaucoma, as explained in
               the article.

In babies, doctors might notice eye shape or size issues that are clues a child
might have glaucoma. Babies with glaucoma may have:

  • large eyes
  • a dull or cloudy eye
  • tears when not crying
  • redness in the sclera (the white part of the eye)
  • sensitivity to light
  • a lot of blinking

Older children and teens may have:

  • blurry vision
  • nearsightedness that gets worse
  • trouble seeing things off to the side
  • headaches

A child also can have glaucoma with no symptoms. That’s why it’s important for
kids to have regular eye exams as they grow up.

What Causes Glaucoma?

The cause of glaucoma can vary from child to child. Sometimes
a child inherits it from a parent. Other times doctors don’t know the cause.

Other causes include:

  • a change (mutation) in a child’s DNA
  • a medical condition, disease, or eye injury
  • eye surgery or other surgery
  • medicine (like a steroid)

How Is Glaucoma Diagnosed?

A pediatric eye specialist (ophthalmologist or optometrist) will do a glaucoma
test and a full eye exam. They check the pressure in the eyes and look inside the
eyes for any damage to the optic nerve. Sometimes doctors get an optical coherence
tomography (OCT) test to look for early damage to the optic nerve.

In older kids, the doctor will check the child’s eyesight and how well they can
see above, below, and to the sides when looking straight ahead (visual fields).

How Is Glaucoma Treated?

An eye surgeon (pediatric ophthalmologist) usually treats children who have glaucoma.
Depending on the child’s age, the cause of the glaucoma, and other things, treatment
may include:

  • making changes to medicines taken for another problem
  • eye drops or medicines taken by mouth
  • surgery, including laser treatments

Surgery is usually the best treatment for babies or young kids. The goal is to
fix the eye so that more fluid drains out or it makes less fluid.

After treatment, the eye doctor will check the pressure again and do other tests.
Some kids may need more than one treatment to keep the pressure down and prevent damage.

How Can Parents Help?

Eye pressure can change during puberty
and at other times in a person’s life. So kids and teens should get their eyes checked
during childhood and throughout adulthood.

If your child has glaucoma, here’s how you can help:

  • Take your child to all follow-up doctor visits.
  • Give your child eye drops or medicines as prescribed.
  • Ask your child’s care team about support groups and other resources in your community.
    For example, assistive tools and low-vision services can help kids with vision loss.
