Anything that irritates the eyes can also irritate the eyelids and lead to swelling. The most familiar cause of irritation is an allergy, which can make one or both lids crinkled or swollen. Allergic reactions may be caused due to cosmetics, pollen or other particles in the air, metals such as nickel, or drugs placed into the eye as eye drops. Stings or bites from insects or infections from bacteria, viruses, or fungi can also reason the eyelids to swell. Trichinosis, due to a roundworm infection, can also reason the eyelids to swell. Hereditary angioedema, a genetic disorder, may reason episodes of eyelid swelling. Dry eyes may get on your nerves both the eyeball and eyelids.

Cause of swelling

Removing the reason of swelling, where possible and applying cold compresses may relieve the swelling. If an allergy is the reason, avoiding the allergen can relieve the swelling and reduce the risk of future episodes. Antihistamines may help, and a doctor may also set down a corticosteroid ointment for the eyelid. If a foreign object, such as a bug stinger, is lodged in the eyelid, it must be removed. Bacterial infections are treated through an antibiotic; fungal infections are treated through an antifungal drug. Hereditary angioedema has unambiguous treatment. Eyelid swelling can be dispersing or solid, acute or chronic, isolated or part of a syndrome. The differential diagnosis of solid, chronic, and isolated eyelid bulge comprises tumors of multiple origins.

Conclusion

On clinical grounds it is generally easy to distinguish between preseptal cellulitis, a cutaneous infection not threatening to vision, and orbital cellulitis, a potentially vision threatening infection of the orbital tissues generally arising from Para nasal sinusitis. We lately cared for two patients with a clinical diagnosis of preseptal cellulitis who had CT scan evidence of subperiosteal abscess. Antibiotic therapy alone resulted in clinical decree in each case. A swollen eyelid is not a diagnosis but quite a sign of an underlying disorder. Two potentially grave causes of red, swollen eyelids are preseptal and orbital cellulitis. Many distended eyelids will be associated with blepharitis or a hordeolum. If the bulge is localized to a "bump" on the lid, this may be indicative of a chalazion. Prolapse of orbital fat, usually associated with aging, is usually found on the inside corner of the upper eyelid. Urticaria or angioedema are uncommon causes of red, swollen eyelids and are immune-mediated. A accumulation of the lacrimal gland is also rare.
