What causes redness and swelling of a child's eyelids, and what should be done?

Generally, redness and swelling of a child's eyelids may be caused by factors such as vitamin A deficiency, insect bites, allergic reactions, blepharitis, or conjunctivitis. These conditions can be improved through dietary adjustments, avoiding allergens, and medical treatments. If symptoms persist, prompt medical attention is recommended. Detailed explanations are as follows:

1. Vitamin A Deficiency

A deficiency in vitamin A may lead to red and swollen eyelids, often accompanied by dryness and peeling around the eyes. Parents can provide children with foods rich in vitamin A, such as pork liver, egg yolks, and spinach.

2. Insect Bites

In summer or warm environments, insect bites may cause redness and swelling of the eyelids, often accompanied by itching. Parents can apply anti-itch and anti-inflammatory ointments as directed by a physician, such as paeonol ointment or compound betamethasone and camphor cream. It is important to prevent the child from scratching the area to avoid infection.

3. Allergic Reaction

Exposure to allergens such as pollen, dust mites, or certain foods may trigger an allergic reaction, causing redness, swelling, and itching of the eyelids. It is advisable to avoid known allergens, and wearing a mask outdoors may help reduce exposure.

4. Blepharitis

Blepharitis is usually caused by bacterial infection and is characterized by localized redness, swelling, and pain in the eyelid. In severe cases, an abscess may form. Parents can consult a doctor and administer medications such as levofloxacin hydrochloride eye drops or tobramycin eye drops to help alleviate symptoms.

5. Conjunctivitis

Conjunctivitis is commonly caused by bacterial or viral infections, presenting with red and swollen eyelids, red eyes, and increased eye discharge. Parents can administer medications such as tobramycin eye drops or erythromycin eye ointment according to medical advice to relieve symptoms.

During treatment, parents should closely monitor the child's symptoms and take timely action when necessary. Additionally, supervision is important to ensure good personal hygiene habits, such as discouraging the child from rubbing their eyes to prevent worsening of the infection and to support recovery.
