What is the cause of redness and swelling of the canthus skin?

Eye skin redness may be caused by allergies, styes, chalazion and other reasons.

1. Allergy

If the patient's eyes touch allergens, such as pollen, dust mites, animal hair, etc., it may induce local allergic reactions, resulting in redness and itching of the eye skin.

2. Sties

are acute suppurative inflammatory lesions that occur in the eyelid glands. Inflammatory factors can stimulate the eyelid gland tissues, causing congestion and edema. Patients also show redness and swelling of the eye skin.

3. Chalazion

is an idiopathic chronic suppurative inflammatory reaction of the meibomian glands. Inflammatory factors can also stimulate the tissues around the meibomian glands, so it can also cause the above symptoms.
