Scleral Edema

The eye protein, or sclera, is formed denseconnective tissue. The sclera is elastic, strong and resistant to stretching and contains few blood vessels, so when the eye protein is swollen there is no significant increase in its volume, but the pain reaction is strongly pronounced.

Depending on the depth of the edema, the area of ​​the lesion and its location, and also on the etiology, that is, the causes, the symptoms will be somewhat different.

Edema of the surface layer of the sclera

Most often is a consequence of allergicreaction. Upon contact with an allergen, an inflammatory mediator is released - chemicals that cause vasodilation, itching and swelling. The pain response is weakly expressed.

An allergen can be dust or pollen, andfood and medicine. Allergic edema usually passes on its own after the contact with the allergen has been eliminated, and antiallergic drugs are rarely required;

Edema of the deep layer of the eye protein

It is caused by a viral or bacterialinfection. With this, pain appears, the whites of the eyes become cloudy, first a red mesh emerges from the enlarged vessels, then the entire sclera becomes uniformly red. There is a lacrimation, with bacterial infection, the formation of purulent foci and rupture of the sclera.

Self-medication in this case is unacceptable, the use of antibacterial and antiviral drugs is necessary. which should appoint a doctor.

Inflammation of the sclera is a complicationautoimmune diseases (rheumatoid arthritis, nodular polyarthritis, Wegener's disease) and specific infections (tuberculosis, syphilis). In the first case, edema is not very pronounced, as a rule, necrosis occurs immediately. With specific infections, a sclera, covering the back of the eyeball, is often inflamed, which is not visible from the outside.
