As chemosis (rare chemosis) swelling (is called edema ) of the conjunctiva (conjunctiva). Due to the increased permeability of the conjunctival vessels, a glassy thickening occurs. The conjunctiva can swell by several millimeters within minutes, step in front of the eyelids and thereby give the eye a noticeable appearance. Chemosis can be accompanied by itching or pain, but it can also go unnoticed by the person affected. Usually chemosis is caused by an inflammatory process such as an allergy or a viral infection . Drainage disorders , for example due to masses in the eye socket ( endocrine orbitopathy ) or dehydration in lagophthalmos and pathologies in the cavernous sinus, can cause chemosis. An entrapment of the prolapsed conjunctiva, for example due to eyelid swelling, can lead to a vicious circle .
As far as possible, treatment is based on the cause. In addition to wetting therapy , anti-inflammatory eye drops such as antihistamines are used.
