Glaucoma living in children
Informed by recognized medical guidance
Overview
Glaucoma is a group of eye conditions that damage the optic nerve, the cable that connects your eye to your brain. In children, glaucoma is often present at birth (congenital) or develops in early childhood. It happens when the fluid inside the eye doesn't drain properly, causing pressure to build up and harm the optic nerve.
Key facts
- Childhood glaucoma is rare but serious.
- Early treatment can help protect a child's vision for life.
- Symptoms may include cloudy eyes, sensitivity to light, or unusually large eyes.
No, childhood glaucoma is rare, affecting about 1 in 10,000 to 1 in 15,000 children.
It can affect newborns, infants, and young children. Some children are born with it (primary congenital glaucoma), and others develop it due to other eye conditions, eye surgeries, or certain medical problems.
Symptoms
- Sudden, severe eye pain
- Nausea or vomiting with eye pain
- Sudden loss of vision in one or both eyes
- ⚠A child's eye that is red, painful, and sensitive to light
- ⚠A cloudy or enlarged eye that seems different from the other
- ⚠Noticeable vision changes in your child
Common symptoms
- Gradual loss of side (peripheral) vision
- Tunnel vision (only seeing straight ahead)
- Eye pain or redness
- Seeing halos around lights
Symptoms in children
- Cloudy or hazy cornea (the clear front part of the eye)
- Unusually large eyes (called buphthalmos – 'ox eye')
- Excessive tearing
- Sensitivity to light (photophobia)
- Frequent eye rubbing
- Squinting or keeping eyes closed often
Causes
Main causes
- Blockage of the eye's natural drainage channels (trabecular meshwork)
- Abnormal development of the eye's drainage system before birth
- Other eye conditions, such as aniridia (missing iris) or Axenfeld-Rieger syndrome
- Previous eye surgery or injury
- Use of steroid medications (in certain cases)
Risk factors
- Family history of childhood glaucoma
- Certain genetic conditions, like Sturge-Weber syndrome or neurofibromatosis
- Being born prematurely
- Having other eye abnormalities present at birth
When to see a doctor
See a doctor urgently if:
- If your child has any of the emergency symptoms listed above, call your local emergency number immediately.
- If your child has a red, painful eye or sudden vision changes, see a doctor the same day.
Book a routine appointment if:
- Regular eye exams are important for all children, but especially if your child has risk factors for glaucoma.
- If your child has been diagnosed with glaucoma, follow the recommended check-up schedule with your eye specialist.
Diagnosis
Glaucoma in children is diagnosed through a thorough eye exam, often performed under anesthesia for very young children. The doctor checks the eye pressure, examines the optic nerve, and looks at the drainage area of the eye.
Tests that may be done
- Tonometry – measuring the pressure inside the eye
- Ophthalmoscopy – examining the optic nerve at the back of the eye
- Gonioscopy – inspecting the drainage angle of the eye
- Measuring the size of the cornea and the length of the eyeball
- Visual field test – mapping side vision (older children only)
What to expect at your appointment
Your child may need several tests over different visits. The doctor will explain each step and help your child feel comfortable. You will be closely involved in the care plan.
Treatment
Treatment for childhood glaucoma aims to lower the pressure inside the eye to protect the optic nerve. The type of treatment depends on the cause and severity.
Self-care at home
- Follow the doctor's instructions for giving any prescribed eye drops or medications exactly as directed.
- Keep all follow-up appointments and report any changes in your child's eyes or vision right away.
- Protect your child's eyes from injury with proper eye protection during activities.
Medical treatments
Doctors may prescribe eye drops or oral medications to help reduce eye pressure. These medications work by either decreasing the amount of fluid the eye makes or helping the fluid drain better. Never change the dose or stop giving medication without consulting your doctor.
When is surgery considered?
Surgery is often needed for childhood glaucoma, especially when medications alone are not enough. Common procedures include creating a new drainage path (trabeculectomy) or opening the existing drainage areas (goniotomy, trabeculotomy). Your eye specialist will discuss the best option for your child.
Living with this condition
Caring for a child with glaucoma involves daily medication routines, regular doctor visits, and being alert to any changes. Most children can go to school, play, and enjoy normal activities with the right care.
Lifestyle tips
- Ensure your child wears proper eye protection during sports and outdoor play.
- Use sunglasses or a hat outdoors to reduce light sensitivity.
- Teach older children about their condition and how to communicate symptoms.
Diet and exercise
No special diet is proven to treat glaucoma, but a healthy, balanced diet supports overall health. Regular physical activity is encouraged, but consult your doctor about any contact sports.
Mental health and emotional wellbeing
Caring for a child with a chronic condition can be stressful. It's normal to feel anxious or overwhelmed. Talk to your doctor about support, and consider speaking with a counsellor. If you or your child experience signs of depression or anxiety, reach out for help. Crisis support is available – call a mental health helpline or your local emergency number.
Prevention
Most cases of childhood glaucoma cannot be prevented, but early detection and treatment can prevent significant vision loss. If you have a family history, talk to your doctor about early eye exams for your child.
Screening programmes
In many places, newborns receive a basic eye check. For children at higher risk (e.g., family history, certain syndromes), an eye specialist may recommend regular pressure checks and optic nerve exams starting from birth.
Complications
If left untreated
- Permanent damage to the optic nerve
- Progressive loss of vision that can lead to blindness
- Clouding of the cornea (corneal edema)
- Poor vision development (amblyopia) in the affected eye
- Increased eye size and potential changes in eye shape
Long-term outlook
With early diagnosis and modern treatment, the outlook for children with glaucoma is hopeful. Many children maintain useful vision and can lead full, active lives. Lifelong follow-up is needed, but treatments continue to improve. You and your child are not alone – your healthcare team is there to support you every step of the way.
