Neonatal glaucoma causes complications and treatment

Newborns are more vulnerable to certain eye problems that can affect their visual development, and one of the most serious conditions is glaucoma. This disease increases eye pressure and can damage the optic nerve if not detected and treated early. Detecting glaucoma in infants is not always easy, but careful observation by parents and early eye examinations can protect the child from permanent vision loss.In this Dalili Medical article, we’ll explain the main causes of glaucoma in newborns, the most important signs and symptoms to watch for, how doctors diagnose the condition, and the latest treatment and prevention methods to ensure your baby’s vision develops normally and safely.

Do Newborns Get Glaucoma?

Glaucoma, often called “the silent thief of sight,” is commonly associated with older adults, but newborns and infants can also develop it. In babies, it is usually a type called congenital glaucoma, which appears at birth or during early childhood (up to age 5).

What is Congenital Glaucoma?

Congenital glaucoma happens when there is a defect in the eye’s drainage system from birth, causing fluid buildup and increased intraocular pressure. If untreated, it can damage the optic nerve and lead to permanent vision loss.

How Does Glaucoma Affect a Child’s Vision?

If not diagnosed and treated in time, glaucoma may cause irreversible optic nerve damage and even blindness.
But with early detection and proper treatment, children can maintain healthy vision and normal visual development.

⏳ Recovery After Glaucoma Surgery in Children

After surgery, children usually need a few weeks to recover. Regular follow-ups with an ophthalmologist are essential to monitor eye pressure, healing progress, and prevent possible complications.

How Can Parents Detect Glaucoma in Their Baby?

Some signs that should alert parents include:

Abnormally large or bulging eyes
Excessive tearing or watery eyes without reason
Sensitivity to light (baby keeps eyes shut or turns away from light)
Crossed eyes (strabismus) or misaligned eyes

⚠️ Is Glaucoma Dangerous in Newborns?

Yes. Without early intervention, congenital glaucoma can cause permanent blindness due to optic nerve damage.

Can Glaucoma in Infants Be Prevented?

Some cases are genetic or congenital and cannot be fully prevented.
But reducing risk factors is possible by:
- Regular prenatal check-ups
- Preventing maternal infections during pregnancy
- Avoiding harmful medications or toxins
- Ensuring early eye screening after birth

Signs of Failed Glaucoma Surgery in Children

Parents should watch for these red flags after surgery:

Persistent high eye pressure or enlarged eyes
Blurry vision or no improvement
Crossed eyes (possible amblyopia or weak vision)
Severe eye redness or pus-like discharge (may indicate infection)

Any of these require an urgent ophthalmology visit.

Do Children Need Long-Term Follow-Up?

Yes. Since a child’s eyes are still developing, long-term monitoring is essential:

Regular eye pressure checks
Tracking visual development
Using glasses or corrective lenses if needed

Who Is at Higher Risk of Congenital Glaucoma?

Babies with the following factors are at greater risk:

Genetic factors: family history of glaucoma or congenital eye defects
Syndromes: Sturge-Weber, Axenfeld-Rieger, or other rare genetic conditions
Maternal health issues during pregnancy: rubella, syphilis, infections, or harmful medications
Premature birth or low birth weight
Birth complications: oxygen deprivation, trauma during delivery
Associated eye or metabolic disorders

If your baby falls into these categories, regular eye screening is strongly recommended.

Symptoms of Congenital Glaucoma in Newborns

Unlike adults, babies show different warning signs:

Enlarged eyes (Buphthalmos)
- One or both eyes may look abnormally large.
Cloudy or hazy cornea
- Instead of being clear, the cornea looks white, gray, or shiny.
Excessive tearing (Lacrimation)
- Continuous watery eyes, sometimes with mild discharge.
Light sensitivity (Photophobia)
- Baby squeezes eyes shut or avoids looking at light.
Eye misalignment or unusual head posture.

Key Differences: Infant vs. Adult Glaucoma

Feature	Infants	Adults
Cause	Congenital defect in fluid drainage	Age-related blockage or secondary eye disease
Symptoms	Large eyes, tearing, light sensitivity, hazy cornea	Gradual vision loss, halos around lights, headaches
Treatment	Surgery is almost always required	Medication first, surgery if needed
Follow-up	Continuous, strict monitoring	Regular check-ups but less intensive

Severe Sensitivity to Light (Photophobia)

The baby keeps their eyes closed or tries to avoid light.
Parents often notice this when the child is exposed to sunlight or strong indoor lighting.

Corneal Clouding or Halo

The cornea appears less transparent or shows a faint bluish-white haze.
This can often be noticed when looking directly at the baby’s eyes or when taking photos.

Constant Eye Rubbing

The baby rubs their eyes frequently due to discomfort caused by high intraocular pressure.

Weak Visual Response

Delay in tracking surrounding objects or difficulty focusing on faces or toys.
Sometimes accompanied by eye deviation or strabismus due to weak vision.

How Is Congenital Glaucoma Diagnosed?

Diagnosis depends on early medical evaluation and close parental observation. Key steps include:

Medical and Family History
- Asking parents about any family history of glaucoma or eye conditions.
- Monitoring symptoms since birth, such as persistent tearing or light sensitivity.
- Checking for complications during pregnancy or delivery that might affect the eyes.
Clinical Eye Examination
- Eye size: Checking for abnormal enlargement (Buphthalmos).
- Cornea: Looking for clouding or scarring.
- Pupil reaction: Ensuring a normal light response.
- Eye movements: Examining for strabismus due to weak vision.
Measuring Intraocular Pressure (IOP)
- Elevated eye pressure is the main indicator.
- Usually measured with special devices for infants, often under light anesthesia or during sleep.
Retina and Optic Nerve Examination
- Assessing optic nerve health to check for glaucoma-related damage.
- Retinal imaging or ultrasound may be needed if the cornea is too cloudy.
Additional Tests (if necessary)
- Ultrasound Biometry: Measuring eye size and corneal thickness.
- Anterior Segment Imaging: Detecting congenital malformations.

Stages of Congenital Glaucoma

Glaucoma in newborns progresses in different stages depending on eye pressure levels and optic nerve damage:

Early Stage
- Mild to moderate eye pressure.
- Slightly enlarged eye.
- Clear or mildly cloudy cornea.
- Symptoms: persistent tearing, mild light sensitivity, occasional eye rubbing.
Moderate Stage
- Noticeably high eye pressure.
- Enlarged eye with cloudy or bluish cornea.
- Symptoms: strong photophobia, frequent tearing, constant eye rubbing, mild strabismus.
Advanced Stage
- Very high eye pressure affecting retina and optic nerve.
- Cornea fully cloudy.
- Significant eye enlargement.
- Symptoms: vision loss (partial or severe), noticeable strabismus, difficulty tracking objects, eye deformities.
Long-Term Complications
- Permanent blindness.
- Structural deformities in cornea or eye shape.
- Developmental delays due to impaired vision.

Risks of Congenital Glaucoma

If untreated, the condition can lead to serious complications:

Vision loss or blindness: Ongoing optic nerve damage from high pressure.
Corneal and eye deformities: Eye enlargement (Buphthalmos), corneal scarring, reduced vision clarity.
Strabismus (Crossed eyes): Caused by weak or uneven vision.
Delayed visual development: Clear vision is essential for infants’ brain and eye development.
Learning and developmental difficulties: Older children may struggle with concentration, learning, and play activities.
Medical complications: Chronic pain, infections, or intraocular bleeding in advanced cases.

Glaucoma Surgery in Newborns

1. When Is Surgery Needed?

Performed as early as possible after diagnosis, especially if intraocular pressure is very high or there are signs of optic nerve damage.
Early surgery in the first few months can prevent eye enlargement and permanent vision loss.

2. Pre-Operative Preparation

Complete eye exam: pressure measurement, cornea and retina health check.
Blood tests and organ function checks before anesthesia.
General anesthesia is required, performed by a pediatric anesthesiologist.

3. Surgical Procedures

Small incision in the eye to access fluid drainage channels.
Techniques:
- Goniotomy: Opens the anterior drainage channel (mild/moderate cases).
- Trabeculotomy: Used for larger obstructions or failed goniotomy.
- Ahmed Valve Implantation: For severe cases resistant to other surgeries.
Closure: Usually without stitches or with very fine sutures.

4. Post-Operative Care

Short hospital monitoring to check eye pressure and rule out bleeding or infection.
Eye drops prescribed:
- Antibiotics (infection prevention).
- Anti-inflammatory drops (reduce swelling).
Regular follow-up eye pressure checks (weekly at first, then every few months).
Eye protection: shield or cover, especially during sleep.

Prevention of Glaucoma in Infants

While congenital glaucoma cannot always be prevented, early care and monitoring reduce risks:

1. Prenatal Care

Regular maternal check-ups during pregnancy.
Prevent infections like rubella, syphilis, or severe eye infections.
Avoid harmful medications without doctor approval.
Eat a healthy diet rich in vitamins and minerals for eye development.

2. Early Screening After Birth

Routine newborn eye check-up to rule out glaucoma or congenital defects.
Watch for early signs (red eyes, constant tearing, white spot in the eye).

3. Protecting the Eyes from Injury

Prevent head or eye trauma during play.
Use protective glasses in older children for sports or risky activities.

4. Preventing Infections

Wash hands before touching or cleaning the baby’s eyes.
Clean eye discharge with sterile cotton.
Avoid sharing towels, pillows, or baby items.
Treat eye or respiratory infections promptly.

5. Healthy Nutrition for Eye Health

Vitamin-rich foods: carrots, sweet potatoes, citrus fruits, spinach, nuts.
Omega-3s: fish (for older kids) or doctor-approved supplements.
Limit processed foods and sugars.

6. Regular Eye Check-ups

Routine pediatric ophthalmologist visits, especially if there’s a family history of glaucoma.
Early detection ensures treatment before vision damage occurs.

⚠️ Parental Alert:
Prevention and early detection are more effective than late treatment. Any unusual eye symptoms in your baby should be checked immediately by a pediatric eye specialist.
