The most common cause of eyelid swelling is eye allergies. Eye allergies sometimes cause significant discomfort, often interrupting daily activities with annoying symptoms such as eyelid irritation and swelling. Eye allergies develop when the immune system overreacts to a certain allergen.
In addition to the disorders listed in Some Causes of Eyelid Swelling, eyelid swelling may result from the following: Disorders that may involve the eyelid but do not cause swelling unless very advanced (eg, eyelid tumors, including squamous cell carcinomas and melanoma) Disorders that cause swelling that begins and is usually most severe in structures near, but not part of, the eyelids (eg, dacryocystitis, canaliculitis) Disorders in which swelling occurs but is not the presenting symptom (eg, basilar skull fracture, burns, trauma, postsurgery)
