Baby has bloody tears
Blood-tinged tears in babies may be caused by eye irritation, dry eyes, conjunctivitis, dacryocystitis, keratitis, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a professional doctor. Specific analysis is as follows:

1. Eye irritation: When a baby's eyes are exposed to external irritants such as dust or sand entering the eye, it may cause tiny blood vessels in the eye to rupture, leading to bloody tears. It is advised to regularly clean the baby’s toys and bedding to reduce the chance of foreign objects entering the eyes. If a foreign object is found in the eye, gently wipe it away with a clean cotton swab or tissue; seek medical help when necessary.
2. Dry eyes: Prolonged screen time or staying in air-conditioned rooms for extended periods may lead to eye dryness in babies, causing discomfort and rupture of small blood vessels, resulting in the aforementioned symptoms. It is recommended to limit the baby’s screen time and use a humidifier indoors to maintain appropriate indoor humidity, which can help alleviate these symptoms.
3. Conjunctivitis: Conjunctivitis may be associated with viral infections, exposure to smoke or dust, and common symptoms include redness, swelling, and tearing of the eye. In severe cases, blood-tinged tears may occur. Parents should administer medications such as levofloxacin eye drops, acyclovir eye ointment, or olopatadine hydrochloride eye drops to the baby according to medical advice.
4. Dacryocystitis: Dacryocystitis may result from infection or blockage of the tear sac. Common symptoms include excessive tearing and eye redness and swelling. In severe cases, this condition may lead to bloody tears. Parents should follow medical instructions to treat the baby with herbal eye drops such as houttuynia cordata eye drops, moxifloxacin hydrochloride eye drops, or pranoprofen eye drops.
5. Keratitis: Keratitis is usually caused by eye injuries, low immunity, or similar factors. Symptoms include eye pain and blurred vision, and in severe cases, bloody tears may also appear. Parents should administer medications such as tobramycin eye drops, compound taurine eye drops, or fluconazole eye drops to the baby under a doctor's guidance to improve symptoms.
In daily life, parents should prevent babies from rubbing their eyes, maintain good eye hygiene, encourage the baby to drink warm water regularly, and take proper care measures, all of which are beneficial for recovery.
