The most common symptoms of conjunctivitis

summary

Conjunctivitis is a general term for the inflammatory reaction of conjunctival tissue under the action of external and body factors. Although conjunctivitis itself does not affect vision seriously, when its inflammation affects the cornea or causes complications, it can lead to visual impairment. Is conjunctivitis the most common symptom? Let's talk about it

The most common symptoms of conjunctivitis

Conjunctival congestion. The characteristic of conjunctival vascular congestion is that the closer to the fornix, the more obvious the congestion is. The blood vessels are reticular and bright red. They can extend into the periphery of the cornea to form corneal pannus. Subconjunctival hemorrhage. Most of them are punctate or small flake. Epidemic hemorrhagic conjunctivitis caused by virus can often be accompanied by subconjunctival hemorrhage.

secretion. Purulent secretion was more common in gonococcal conjunctivitis; Mucous purulent or catarrhal secretions are often found in bacterial or chlamydial conjunctivitis, which can be firmly adhered to the eyelashes, making it difficult to open the eyelids in the morning; Watery secretions are usually seen in viral conjunctivitis.

Membrane and pseudomembrane. Membrane is cellulose exudation attached to conjunctiva surface, pseudomembrane is easy to peel off, but true membrane is not easy to separate, wound bleeding after forced peeling, the essential difference between the two lies in the difference in the degree of inflammatory reaction, the inflammatory reaction of true membrane is more severe, diphtheria caused serious membranous conjunctivitis; β- Hemolytic streptococcus, pneumoniae, Neisseria gonorrhoeae, adenovirus and inclusion bodies can cause membranous or pseudomembranous conjunctivitis.

matters needing attention

Don't cover the affected eyes, because there are many secretions in conjunctivitis. If the affected eyes are covered, the secretions are not easy to discharge, and they are stored in the conjunctival sac; And after covering, the temperature of conjunctival sac will rise, which is more conducive to the reproduction of bacteria and aggravates conjunctivitis. To keep hands and toiletries clean, we should develop the habit of washing hands frequently and protecting eyes. Toiletries should be disinfected independently and frequently to reduce the growth of bacteria.
