Children's lower eyelid redness and swelling

As the saying goes, eyes are the windows to the soul, but eyes are also a very fragile part, especially for children, who have low immunity and are easily infected by bacteria and viruses. Children can get hurt if you are not careful while playing. If you find that the child's lower eyelids are red and swollen, you must deal with it in time to avoid conjunctivitis caused by bacterial infection. Conjunctivitis is a very serious eye disease. And it is not easy to treat. Let’s follow the editor to learn about it.

Eyelid swelling and pain is caused by bacterial conjunctivitis infection, which leads to blockage of the meibomian gland duct. The symptoms are mainly redness, pain and itching. It is best to use ichthyol external bandage to reduce swelling. Apply 10ml of sodium chloride injection and eye drops made with Pioneer No. 5 four or five times a day.

(1) Conjunctival congestion The characteristic of conjunctival vascular congestion is that the closer to the dome, the more obvious the congestion. The blood vessels are distributed in a reticular manner, are bright red in color, and can extend into the periphery of the cornea to form corneal pannus.

(2) Purulent discharge is more common in gonococcal conjunctivitis; mucopurulent or catarrhal discharge is more common in bacterial or chlamydial conjunctivitis, and often adheres firmly to the eyelashes, making it difficult to open the eyelids in the morning; watery discharge is usually seen in viral conjunctivitis.

(3) Conjunctival chemosis Conjunctival inflammation causes conjunctival blood vessel dilation and exudation, leading to tissue edema. Because the bulbar conjunctiva and fornix conjunctiva tissues are loose, they bulge out significantly when edematous.

(4) Subconjunctival hemorrhage is mostly in the form of dots or small patches. Epidemic hemorrhagic conjunctivitis caused by viruses is often accompanied by subconjunctival hemorrhage.

(5) The papilla is a nonspecific sign of conjunctival inflammation and can be located on the palpebral conjunctiva or corneal limbus. It presents as a raised polygonal mosaic appearance with areas of hyperemia separated by pale grooves.

(6) Follicles Follicles are yellow-white, smooth, round protrusions with a diameter of 0.5 to 2.0 mm. However, in some cases, such as chlamydial conjunctivitis, larger follicles may also appear. Viral conjunctivitis and chlamydial conjunctivitis are often accompanied by obvious follicle formation and are called acute follicular conjunctivitis or chronic follicular conjunctivitis.

(7) Membrane and pseudomembrane Membrane is a cellulose exudate attached to the surface of the conjunctiva. Pseudomembranes are easy to peel off, while true membranes are not easy to separate. After forced peeling, the wound will bleed. The essential difference between the two lies in the difference in the degree of inflammatory response. The inflammatory response of true membrane is more severe. Corynebacterium diphtheriae causes severe membranous conjunctivitis; β-hemolytic streptococci, Klebsiella pneumoniae, gonococci, adenovirus, inclusion bodies, etc. can all cause membranous or pseudomembranous conjunctivitis.

(8) Damage to scar matrix tissue is the histological basis of conjunctival scar formation. Early manifestations of conjunctival scarring include narrowing of the conjunctival fornix and subepithelial fibrosis of the conjunctiva.

(9) Swollen preauricular lymph nodes Viral conjunctivitis is often accompanied by swollen preauricular lymph nodes.

(10) Pseudoptosis is a mild ptosis caused by hypertrophy of the upper eyelid tissue due to cell infiltration or scar formation, which is more common in the late stage of trachoma.

(11) Conjunctival granuloma is less common and can be seen in chronic inflammation caused by tuberculosis, leprosy, syphilis and rickettsia.
