Many pediatric vision problems and eye diseases can be corrected if detected and treated early. When it comes to your child’s eyes, high-quality pediatric ophthalmology care is of the utmost importance. Pediatric eye problems are often very different from adult eye diseases and pediatric ophthalmologists (eye doctors who are also surgeons) are specially trained to manage and treat children's eye conditions.
- amblyopia (lazy eye: with one weak eye and one strong one)
- blocked tear ducts and defects (from the ducts not forming correctly)
- glaucoma (damage to the optic nerve from a build-up of pressure in the eye)
- cataract (a clouding of the eye’s lens)
- eye injuries
- ptosis (drooping eyelid)
- refractive errors (nearsightedness, farsightedness, astigmatism)
- retinopathy of prematurity (a disease that occurs in premature babies and causes abnormal blood vessels to grow in the retina)
- retinoblastoma (a type of tumor involving the retina)
- retinitis pigmentosa (RP) and other retinal dystrophies (diseases that cause damage to the retina
- strabismus (wandering eye or “cross eyes”)
Children whose parents or siblings have eye conditions, such as strabismus or amblyopia, are more likely to have these eye disorders themselves, even if they don't have obvious signs of pediatric eye problems.
If your child has a certain medical condition such as diabetes, or a genetic disease like neurofibromatosis, it's a good idea to have regular pediatric eye exams with a pediatric ophthalmologist.
Early signs of serious pediatric eye problems, which should be evaluated by a doctor, include:
- poor vision
- eye pain
- changes in the shape or size of an eye
- crossed or wandering eyes
- abnormal appearance of the pupil of one or both eyes
Genetic conditions can often cause eye problems in children. In these cases, our pediatric ophthalmologists collaborate with multi-disciplinary Nemours teams who treat children with genetic syndromes.
If your child is healthy and has no known risk factors for pediatric eye problems, then age-appropriate screening examinations with your primary care provider should be sufficient. If further evaluations are indicated, your child can be referred to our ophthalmologists as needed.

Tear-Duct Obstruction and Surgery
Many babies are born with an underdeveloped tear-duct system, a problem that can lead to tear-duct blockage, excess tearing, and infection.
Blocked tear ducts are common in infants; as many as one third may be born with this condition. Fortunately, more than 90% of all cases clear up by the time children are 1 year old with little or no treatment.
About Tear Ducts
Our eyes are continually exposed to dust, bacteria, viruses, and other things that could cause damage, and the eyelids and eyelashes play a key role in preventing that.
Besides being protective barriers, the lids and lashes also help the eyes stay moist. Without moisture, the corneas would dry out and could become cloudy or injured.
Working with the lids and lashes, the protective system of glands and ducts (called the lacrimal system) keeps eyes from drying out. Small glands at the edge of the eyelid produce an oily film that mixes with the liquid part of tears and keeps them from evaporating.
Lacrimal (or tear-producing) glands secrete the watery part of tears. These glands are located under the browbone behind the upper eyelid, at the edge of the eye socket, and in the lids.
Eyelids move tears across the eyes. Tears keep the eyes lubricated and clean and contain antibodies that protect against infection. They drain out of the eyes through two openings (puncta, or lacrimal ducts), one on each of the upper and lower lids.
From these puncta, tears enter small tubes called canaliculi or ducts, located at the inner corner of the eyelids, then pass into the lacrimal sac, which is next to the inner corner of the eyes (between the eyes and the nose).
From the lacrimal sacs, tears move down through the nasolacrimal duct and drain into the back of the nose. (That's why you usually get a runny nose when you cry — your eyes are producing excess tears, and your nose can't handle the additional flow.) When you blink, the motion forces the lacrimal sacs to compress, squeezing tears out of them, away from the eyes, and into the nasolacrimal duct.
The nasolacrimal duct and the lacrimal ducts are also known as tear ducts. It's the nasolacrimal duct that's usually involved in tear-duct blockage in babies.
Causes of Blocked Tear Ducts
Many babies are born without a fully developed nasolacrimal duct. This is called congenital nasolacrimal duct obstruction or dacryostenosis. Most commonly, an infant is born with a duct that is too narrow or has a web of tissue blocking the duct, so it doesn't drain properly or becomes blocked easily. Most kids outgrow this by the first birthday.
Other causes of blockage, especially in older kids, are rare. Some kids have nasal polyps, which are cysts or growths of extra tissue in the nose at the end of the tear duct. A blockage also can be caused by a cyst or tumor in the nose, but again, this is very unusual in children.
Trauma to the eye area or an eye injury that lacerates (cuts through) the tear ducts also could block a duct, but reconstructive surgery right after the accident or injury may prevent this.
Signs of Blocked Tear Ducts
Babies with blocked tear ducts usually develop symptoms between birth and 12 weeks of age, although the problem might not be apparent until an eye becomes infected. The most common signs are excessive tearing, even when a baby is not crying (this is called epiphora). You also may notice pus in the corner of the eye, or that your child wakes up with a crust over the eyelid or in the eyelashes.
Babies with blocked tear ducts can develop an infection in the lacrimal sac called dacryocystitis. Signs include redness at the inner corner of the eye and a slight tenderness and swelling or bump at the side of the nose.
Some infants are born with a cyst in the lacrimal sac, causing a swollen blue bump called a dacryocystocele to appear next to the inside corner of the eye.
Although this condition should be watched closely by a doctor, it doesn't always lead to infection and can be treated at home with firm massage and observation. If it becomes infected, topical (applied to the skin) antibiotics might be needed.
However, with some infections, a baby may need to be treated in a hospital with IV (intravenous, given into a vein) antibiotics, followed by surgical probing of the duct.
When to Call the Doctor
If your baby's eyes tear excessively but show no sign of infection, call your doctor or a pediatric ophthalmologist (eye specialist). Early treatment of a blocked duct may prevent the need for surgery.
If there are signs of infection (such as redness, pus, or swelling) or if a mass or bump is felt on the inside corner of the eye, call your doctor immediately because the infection can spread to other parts of the face and the blockage can lead to an abscess if not treated.
Treating Blocked Tear Ducts
Kids with blocked tear ducts often can be treated at home. Your doctor or pediatric ophthalmologist may recommend that you massage the eye several times daily for a couple of months.
Before massaging the tear duct, wash your hands. Place your index finger on the side of your child's nose and firmly massage down toward the corner of the nose. You may also want to apply warm compresses to the eye to help promote drainage and ease discomfort.
If your baby develops an infection as a result of the tear-duct blockage, the doctor will prescribe antibiotic eye drops or ointment to treat the infection. It's important to remember that antibiotics will not get rid of the obstruction. Once the infection has cleared, you can continue massaging the tear duct as the doctor recommends.
If your baby still has excess tearing after 6 to 8 months, develops a serious infection, or has repeated infections, the doctor may recommend that the tear duct be opened surgically. This has an 85% to 95% success rate for babies who are 1 year old or younger; the success rate drops as children get older. Surgical probing may be repeated if it's not successful right away.
The probe should be done by an ophthalmologist. Probes are done on an outpatient surgery basis (unless a baby has a severe infection and has already been admitted to the hospital) under general anesthesia.
The ophthalmologist first will do a complete eye exam to rule out other eye problems or types of inflammation that could cause similar symptoms. A dye disappearance test may help determine the cause of the problem. This involves placing fluorescein dye in the eye (a harmless orange colored dye)and then examining the tear film (the amount of tear in the eye) to see if it's greater than it should be. The doctor may wait to see if dye has drained properly by having the child blow his or her nose and then checking to see if any of the dye exited through the nose.
A surgical probe takes about 10 minutes. A thin, blunt metal wire is gently passed through the tear duct to open any obstruction. Sterile saline is then irrigated through the duct into the nose to make sure that there is now an open path. There's very little discomfort after the probing.
If the initial surgical probing is unsuccessful or if a child is older or has a particularly difficult blockage, the doctor may recommend another surgical treatment. One option is called silicone tube intubation, in which silicone tubes are placed in tear ducts to stretch them. The tubes are left in place for as long as 6 months and then removed in another short surgical procedure or in the doctor's office, depending on the type of stent used.
Another treatment is balloon catheter dilation (DCP). In DCP, a balloon is inserted through an opening in the corner of the eye and into the tear duct, then inflated with a sterile solution to expand the tear duct. The balloon is then deflated and removed.
Both of these procedures are fairly short but require that a child be put under anesthesia. Both are generally successful, with an 80% to 90% success rate in younger kids.
It may take up to a week after surgery before symptoms improve. Your doctor will give you antibiotic ointment or drops along with specific instructions on how to care for your child.
