Symptoms of chronic conjunctivitis in children: you must know these

Parents should pay more attention to their children. If they find any abnormal behavior in their children, they should pay attention. Because children do not know how to protect their eyes, they are often more prone to conjunctivitis. At this time, some corresponding symptoms will appear. Parents should understand and be vigilant.

1. Increased secretions

According to the characteristics of conjunctival secretions, they can be divided into: watery secretions, viscous secretions, purulent secretions and mucopurulent secretions. The secretions mainly come from the lacrimal glands, accessory lacrimal glands, goblet cells, and are mixed with exudative inflammatory cells, pathogenic microorganisms, and necrotic tissue. Generally speaking, watery secretions are more common in viral and drug-toxic conjunctivitis; sticky secretions are more common in allergic conjunctivitis, spring catarrhal conjunctivitis, or conjunctivitis accompanied by tear secretion disorders; purulent secretions are often characteristic manifestations of acute bacterial conjunctivitis; mucopurulent secretions are more common in trachoma or bacterial conjunctivitis.

2. Subconjunctival hemorrhage

The rupture of small blood vessels under the conjunctiva causes blood to enter the subconjunctival tissue space and become subconjunctival hemorrhage, which may appear in the form of dots or sheets and is generally bright red. When the amount of bleeding is large, it may be dark red. The local conjunctiva may bulge, and bleeding from small blood vessels close to the corneal margin may form a localized subconjunctival hematoma. Subconjunctival hemorrhage is common in epidemic hemorrhagic conjunctivitis, Koch-Weeks bacillary conjunctivitis and severe adenoviral conjunctivitis.

3. Conjunctival congestion

It manifests as dilation of the surface blood vessels of the conjunctiva, which can be diffuse congestion or local congestion. The color of the congestion is mostly bright red, and the congestion is more obvious towards the dome area and is reduced towards the corneal edge. When there is no obvious edema, the conjunctival blood vessels can be moved by pushing them, and there is no tenderness. After 0.1% epinephrine was dripped on the conjunctival surface, the conjunctival vascular congestion disappeared significantly. When conjunctival inflammation affects the cornea, sclera or fascia tissue at the same time, conjunctival congestion and ciliary congestion may also coexist, which is clinically called mixed congestion.
