Newborn eye discharge is commonly caused by conjunctivitis, but it may also occur with a cold, flu, or a blocked tear duct. This discharge is usually yellow and can appear liquid or crusted, often collecting along the lower eyelid.
Newborn eye discharge may occur with symptoms like redness, tearing, and itching, and babies may rub their eyes, which can worsen irritation. The timing of symptoms and the appearance of the discharge can help differentiate between conditions like a blocked tear duct and conjunctivitis.
Treatment for newborn eye discharge depends on the underlying cause and may include cleaning the eyes with saline solution or using prescribed eye drops or antibiotics. In many cases, simple hygiene measures and monitoring symptoms are enough, while more persistent or severe cases require medical evaluation.
Main causes
The main causes of newborn eye discharge are:
1. Cold or flu
A cold or flu can cause symptoms like a plugged nose, coughing, and fever, as well as yellow discharge around the eyes.
What to do: Treatment consists of keeping the baby’s eyes clean and strengthening the immune system with a healthy diet. You can give the baby orange and lemon juice, if not contraindicated by the doctor.
2. Blocked tear duct
The tear duct serves to lubricate the oil and protect it from foreign invaders. Therefore, if the tear duct becomes blocked, tear production becomes compromised, which can lead to the growth of bacteria in the area. This can cause yellow eye discharge, and is most commonly seen in the first weeks of life.
What to do: This obstruction typically improves with treatment given over the first year of life. It consists of cleansing the eyes with saline solution and massaging the area lightly. In serious cases, the pediatrician may recommend a minor surgical procedure.
3. Conjunctivitis
Conjunctivitis in babies is characterized by inflammation of the membranes that line the eyes and the eye lids. It causes eye redness, intense itching, tearing and crust. Read more about pink eye in babies and how it presents.
What to do: Treatment for conjunctivitis in babies should be monitored by a pediatrician and usually involves the use of eyedrops of antibiotic or antihistamine ointments. The doctor will usually recommend cleansing of the eyes with vapor or saline, depending on the type of conjunctivitis.
Normal vs abnormal eye discharge
Newborn eye discharge can vary depending on the baby’s age and underlying cause. Looking at when symptoms appear is an important first step in understanding whether the discharge is likely temporary or related to a medical condition.
Timeline of newborn eye discharge
The timing of symptoms can help distinguish between normal adaptation, blocked tear ducts, and infections.
This timeline helps guide what the most likely cause may be, although clinical symptoms should always be considered alongside age.
Visual patterns and key differences
In addition to timing, the appearance of the discharge can help differentiate between common conditions:
-
Clear or watery discharge is often related to tear duct blockage
-
Yellow or crusted discharge is common in both blocked ducts and mild infections
-
Thick, pus-like discharge with redness may indicate conjunctivitis
Sticky eye usually presents with discharge but little to no redness, while conjunctivitis causes redness, swelling, and more intense irritation. These differences are important for determining the need for medical treatment.
How to clean the baby’s eyes
Warm water should be applied to the baby’s face every day during a bath. Soap or other hygiene products should not be used on the face, as they can irritate the eyes. However, to correctly cleanse the eyes, especially during eye conditions like conjunctivitis, the following steps are recommended:
Step-by-step guide
-
Soak a piece of gauze with saline solution or freshly made, cold chamomile tea.
-
Pass the gauze over one eye, from the inner corner to the outside. This swift movement helps prevent tear duct obstructions.
-
Repeat the process on the other eye using a new piece of gauze to avoid spreading possible bacteria.
The baby’s eyes should be cleaned this way until they are one year old, even if they are asymptomatic.
In addition to keeping the baby’s eyes clean, the nose should also be kept clean and free from discharge, as the tear ducts can become blocked with a plugged nose. This can lead to the growth of viruses or bacteria.
When to see the doctor
You should take the baby to the doctor if eye discharge is yellow and thick and if you need to clean the baby’s eyes at least 3 times per day. If the baby wakes from sleep with heavily crusted eyes and has difficulty opening them, you should take the baby to the doctor for assessment of conjunctivitis.
The baby should also see a doctor if they have other symptoms in addition to eye discharge, like cough, phlegm, fast breathing, fever or irritability, as these may indicate a respiratory infection.
