Pediatric Nasolacrimal Duct Obstruction
Pediatric nasolacrimal duct obstruction (NLDO) is a common condition in infants where there is an obstruction or narrowing in the nasolacrimal duct, which is the drainage system that allows tears to drain from the eyes into the nose. Here are some key points about pediatric NLDO:
Causes
NLDO in infants is typically caused by the incomplete development or obstruction of the nasolacrimal duct. This can lead to tears not draining properly, resulting in excessive tearing, mucus discharge, and sometimes mild swelling around the tear duct area.
Symptoms
The primary symptom of NLDO in infants is persistent tearing, especially when they cry or in windy conditions. You may also notice mucus or discharge in the corner of the eye closest to the nose.
Diagnosis
Pediatric ophthalmologists diagnose NLDO through a physical examination of the eyes and tear ducts. They may perform tests such as dye disappearance test (Jones test) or probing of the tear ducts under anesthesia to determine the severity of the obstruction.
Management Options
Massage
Gentle massage over the tear duct area can help to open the duct by promoting drainage.
Warm Compresses
Applying warm compresses to the tear duct area can also aid in opening the duct.
Antibiotic Drops
If there is any sign of infection, antibiotic eye drops may be prescribed.
Probing and Irrigation
If conservative measures don't resolve the obstruction, a procedure called probing and irrigation may be recommended. This involves inserting a thin probe into the tear duct to clear the blockage.
Prognosis
Most cases of NLDO in infants resolve spontaneously within the first year of life without the need for intervention. However, if the condition persists beyond this period or is associated with repeated infections, further intervention may be necessary.
Surgery
In cases where NLDO persists beyond the first year of life or if there are complications such as recurrent infections, surgical intervention may be considered. This could involve a procedure to open or enlarge the nasolacrimal duct.
Follow-Up
Regular follow-up with a pediatric ophthalmologist is important to monitor the condition and ensure appropriate management.
If you suspect your child may have nasolacrimal duct obstruction or if you notice persistent tearing or eye discharge, it’s essential to consult with a pediatric ophthalmologist for an accurate diagnosis and appropriate management plan tailored to your child’s needs. Early intervention can help prevent complications and ensure optimal eye health for your child.

Frequently Asked Questions
Early Detection of Health Issues: The eyes can provide early signs of various systemic health conditions such as diabetes, hypertension, autoimmune diseases, and even some forms of cancer. During an eye exam, ophthalmologist may detect changes in the blood vessels, optic nerve, and other structures that can indicate these conditions before symptoms appear elsewhere in the body.
Monitoring Overall Well-Being: Regular eye exams help monitor the general health of the eyes, including assessing visual acuity, eye pressure (important for detecting glaucoma), and the overall condition of the retina and optic nerve. Detecting and treating eye conditions early can prevent vision loss and maintain optimal eye function.
Quality of Life: Good vision is crucial for performing everyday tasks, from reading and driving to work and leisure activities. Regular eye check-ups ensure that any changes in vision can be addressed promptly with appropriate corrective measures such as glasses or contact lenses.
Preventative Care: Routine eye exams not only detect existing problems but also help prevent future issues. For example, children should have their eyes checked regularly to detect refractive errors or lazy eye (amblyopia) early, which can affect their development if left untreated.
Diagnosis involves a comprehensive eye exam, including a visual acuity test, pupil dilation, and examination of the lens and retina
Protective eyewear, such as goggles or glasses with impact-resistant lenses, should be worn during sports to prevent eye injuries. Sunglasses with UV protection are also important for outdoor activities.
Common conditions include refractive errors (like nearsightedness, farsightedness, and astigmatism), amblyopia (lazy eye), strabismus (crossed eyes), and pediatric cataracts
Squint surgery involves adjusting the muscles that control the movement of the eyes. It is usually done under general anesthesia. The surgeon makes small incisions in the tissue covering the eye and adjusts the muscles to improve eye alignment. The procedure typically takes about 1-2 hours.Squint surgery is generally safe, especially when performed by an experienced strabismus specialist. As with any surgery, there are risks such as infection, bleeding, or over- or under-correction of the eye alignment. However, complications are rare.
