Why are the corners of the child's eyes red?

Careful parents will observe that many children have redness in the corners of their eyes. This situation may be caused by corneal infection or eye infection. Parents need to actively observe, because if the eyes are infected, not only will the corners of the eyes turn red, but there will also be other physical symptoms, such as tears, decreased body function, frequent blinking, etc.

Red eyes refer to the white of the eye, the so-called white eyeball, which is the redness of the conjunctiva covering the front of the eyeball. It may be caused by local inflammatory stimulation, vascular dilation and congestion;

It may also be caused by rupture of small blood vessels in the conjunctiva due to non-inflammatory factors, which is called subconjunctival hemorrhage. Under normal circumstances, the blood vessels of the conjunctiva are deflated and in a "sleeping" state, and no blood flows through the blood vessels, so the sclera always appears so white and flawless. When invaded by bacteria, viruses, etc., the "sleeping" blood vessels will be immediately "woken up" and then expand.

Then red blood rushed in from all directions, and the sclera turned red. The most obvious symptom of inflamed eyes is red eyes. People with acute or chronic conjunctivitis, various keratitis, iridocyclitis, scleritis, glaucoma, chemical burns of the eyes, etc. may have varying degrees of eye congestion.

There are many reasons for red eyes. Because the bulbar conjunctiva is exposed in front of the eyeball, it is easily attacked by trauma and microorganisms. The most common cause of red eyes is eye inflammation, such as acute conjunctivitis (i.e. pink eye), keratitis, sty, iridocyclitis, etc. Allergic reactions can also cause red eyes, such as allergic conjunctivitis caused by allergies to certain eye drops (tetracycline, atropine, etc.), and spring conjunctivitis, which can also be accompanied by symptoms such as eyelid edema and stinging. Eye surgery and trauma can also cause red eyes, which can be congestive

It can also be hemorrhagic; fever, crying or air pollution can also cause conjunctival congestion and manifest as red eyes; severe coughing, vomiting, and hard rubbing can cause small blood vessels in the conjunctiva to rupture and bleed, manifesting as punctate or flake redness under the conjunctiva, and the color may be dark red or bright red depending on the amount of bleeding and time.
