Why does the white of a child's eye turn red?

It is quite common for children to have red whites of their eyes. There are many reasons for this. It may be caused by an infectious disease in the eye, trauma, an adverse allergic reaction, or conjunctivitis. To treat this disease, we need to understand its cause and prescribe the right medicine. Below we will introduce in detail why children's whites of the eyes turn red.

reason

1. Eye infections

The most common cause of red eyes in children is infectious eye diseases, such as acute conjunctivitis. In addition to red eyes, there is also secretion. Vision is generally not affected, or vision may be slightly blurred. If inflammation occurs in the cornea, iris, ciliary body or intraocular tissue, redness of the eyes may occur suddenly, accompanied by irritation symptoms such as photophobia and tearing, and vision may also be affected. In addition, inflammation of the eyelid skin near the eyeball, styes (commonly known as stye) or orbital infection can all cause red eyes. You should go to an ophthalmologist for treatment and ask the doctor to diagnose and prescribe medication according to your condition.

2. Red eyes caused by physical stimulation

Red eyes in children are not necessarily caused by inflammatory stimulation. It may be caused by rupture of small blood vessels in the conjunctiva due to non-inflammatory factors, which is called subconjunctival hemorrhage. Severe coughing, vomiting, and vigorous rubbing of the eyes can cause rupture and bleeding of small blood vessels in the conjunctiva, which manifests as punctate or flake-like redness under the conjunctiva. The color may be dark red or bright red depending on the amount of bleeding and time. It is usually not accompanied by symptoms such as photophobia and tearing. It will recover automatically in about a week. Just pay attention to rest.

3. Pink Eye

Pink eye, also known as acute epidemic conjunctivitis, is an eye disease transmitted through contact, such as contact with patients' used face-washing utensils, faucets, door handles, shared toys, etc. It is often widely spread in kindergartens and schools. Symptoms include: hot eyes, photophobia, dry eyes, red and swollen eyelids, excessive eye discharge, tears, etc. Parents should take their children to the hospital for examination, rinse their eyes with saline 2-3 times a day, use antibiotic eye drops, etc., and do not rub their eyes with their hands.

4. Allergic reaction

Any foreign matter entering the eyes may cause eye allergies. City dust, car exhaust, spring pollen, pet fur, etc. are all common causes of eye allergies. The main symptoms of allergic conjunctivitis are itchy and red eyes. In severe cases, the eyelids may also become red, swollen and itchy. In addition, it is often accompanied by symptoms of allergic rhinitis such as itchy nose and sneezing. You should ask a doctor for diagnosis and use anti-allergic drugs reasonably.
