How to Identify Buphthalmos in Children?

If you’re worried your child might have buphthalmos, here’s the quick answer. Buphthalmos is a condition where a child’s eyes appear abnormally large due to high pressure inside the eye, often caused by congenital glaucoma.

Recognising early signs is vital because timely detection and treatment can preserve your child’s vision and protect their overall eye health. The good news? With the right knowledge and medical care, managing buphthalmos becomes much easier.

Don’t stress—we’re going to deeply explore this condition and answer all your questions step by step. By the time you reach the end of this guide, you’ll have all the tools and insights to take the right actions for your child.

What Is Buphthalmos and Why Does It Happen?

Buphthalmos, derived from the Greek word meaning “ox eye,” describes a rare condition in which an infant or young child’s eye becomes enlarged due to increased intraocular pressure (IOP). It’s often associated with congenital glaucoma, which is a type of glaucoma present from birth.

How Buphthalmos Develops?

The human eye maintains a balance between the production and drainage of fluid, called aqueous humour. When this balance is disrupted and fluid cannot drain properly, pressure builds up inside the eye. This excessive pressure stretches the fragile eye tissues in children, causing their eyes to enlarge visibly.

Why Early Diagnosis Matters?

Children’s eyes are still soft and developing, making them more susceptible to damage from increased pressure. If left untreated, this can lead to:

Optic Nerve Damage
Corneal Opacity (cloudiness)
Permanent Vision Loss

During my ophthalmology practice, I met a toddler named Ayaan whose parents were concerned about his unusually large eyes. At first, they thought it was just a unique feature, but when they noticed he was sensitive to light and cried frequently, they brought him in.

Quick testing confirmed buphthalmos caused by congenital glaucoma. We began treatment immediately, and today, Ayaan’s vision is stable and well-monitored.

Early Signs and Symptoms of Buphthalmos in Children

Buphthalmos might not be immediately noticeable at birth, but as the condition progresses, certain symptoms become apparent. Here are the early warning signs:

1. Abnormally Large or Bulging Eyes

Affected children typically have eyes that appear noticeably larger or more prominent than usual.
Look closely, especially if the difference is only in one eye.

2. Sensitivity to Light (Photophobia)

Many children with buphthalmos squint or turn their heads away from light sources, as bright lights can be painful.

3. Excessive Tearing (Epiphora)

Constant and unexplained tearing is another red flag, even when the child isn’t crying.

4. Cloudy or Hazy Cornea

The normally clear cornea may appear dull, greyish, or hazy due to damage from high pressure.

5. Abnormal Eye Movements

Some children with buphthalmos may develop difficulties focusing or controlling their eye movements.

6. Irritability or Discomfort

Restlessness, rubbing of the eyes, and frequent crying may indicate discomfort caused by internal eye pressure.

If you’re spotting any of these symptoms, it’s time to visit a doctor. Early intervention makes a world of difference.

Causes and Risk Factors for Buphthalmos

Buphthalmos doesn’t occur randomly. Understanding its underlying causes and risk factors can help you stay prepared.

Common Causes

Congenital Glaucoma (the main cause): This occurs due to developmental issues in the eye’s drainage system before birth.
Hereditary Factors: A family history of glaucoma or other eye conditions increases the likelihood.
Syndromic Associations: Conditions like Sturge-Weber syndrome or neurofibromatosis may include buphthalmos as a symptom.

Risk Factors

Genetics: If one or both parents have a history of glaucoma, there’s a higher chance their child could develop it.
Premature Birth: Some premature babies may be at elevated risk for developmental eye issues.
Maternal Health during pregnancy, such as infections or conditions impacting foetal development.

How Is Buphthalmos Diagnosed by Doctors?

If buphthalmos is suspected, a thorough eye examination is essential. Paediatric ophthalmologists specialise in diagnosing and treating such conditions in children.

Here’s how I usually proceed during such evaluations:

1. History Taking

I ask parents about the child’s health history, family history of eye conditions, and details about symptoms like light sensitivity, tearing, or changes in eye appearance.

2. Eye Examination

Using specialised tools, I’ll assess:

The size of the cornea (enlarged corneas are a giveaway sign of buphthalmos).
Clarity of the cornea (checking for cloudiness).
Response to light and pupil dilation.

3. Measuring Eye Pressure

This is done under gentle sedation in young children to ensure comfort. Elevated intraocular pressure confirms glaucoma.

4. Imaging Tests

Ultrasound or Optical Coherence Tomography (OCT): Provides detailed images of the eye’s internal structures.
Gonioscopy: Examines the drainage angle inside the eye, identifying structural abnormalities.

Early diagnosis ensures the right treatment plan is put into motion, protecting your child’s vision for the future.

Treatment Options for Buphthalmos

Treatment for buphthalmos focuses on reducing pressure inside the eye and preventing vision damage. Options include medications, laser therapy, or surgery, depending on the severity of the condition.

1. Eye Drops and Medications

Purpose: Help reduce intraocular pressure by decreasing fluid production or improving drainage.
Limitation: Often a short-term solution or used post-surgery to support recovery.

2. Laser Treatments

A non-invasive option for mild cases. Laser procedures enhance the eye’s drainage system to lower pressure.

3. Surgery

Surgery is the gold standard for managing moderate-to-severe buphthalmos.
Goniotomy or Trabeculotomy improves the flow of fluid from the eye by opening up blocked channels.
Cyclophotocoagulation for advanced cases involves reducing fluid production in the eye.

Ayaan’s case, for instance, required goniotomy. His parents were initially apprehensive, but the minimally invasive procedure only took a few hours and brought his pressure under control. Regular follow-ups helped maintain his vision.

Long-Term Care and Outlook

Children with buphthalmos often require lifelong monitoring, even after successful treatment. Here’s how families can ensure positive outcomes:

1.Regular Check-Ups

Frequent visits to the ophthalmologist allow early detection of any recurrence or complications.

2.Vision Support

Corrective glasses or visual aids might be necessary if vision isn’t fully restored.

3.Emotional Support

Older children might feel self-conscious about their eyes. Boost their confidence and normalise discussions about their condition.

4.Parental Vigilance

Watching out for symptoms like eye pain, worsening vision, or tearing can help catch potential issues before they escalate.

Common Myths and Misconceptions About Buphthalmos

Myth: “It’s just a cosmetic issue.”
Fact: Untreated buphthalmos can lead to severe vision loss, so it’s far more than a cosmetic concern.
Myth: “Children outgrow it.”
Fact: Buphthalmos doesn’t resolve itself and requires medical attention.
Myth: “Treatment is painful for kids.”
Fact: Modern treatments, including sedation and gentle surgical techniques, minimise discomfort for young patients.
Myth: “It’s too late to treat an older child.”
Fact: While early intervention is ideal, many children and even adults benefit greatly from treatment.

Take Action Today

If your child shows signs of buphthalmos, don’t wait. Schedule a consultation with a paediatric ophthalmologist to get a proper diagnosis. Starting treatment early can drastically improve results and protect your child’s precious vision.

Remember, conditions like buphthalmos are challenging but manageable with the right care team and guidance. Armed with knowledge and timely intervention, you’ll help your child see a brighter future, literally and figuratively. Why wait? Their vibrant, clear-eyed tomorrow starts today!
