Differential Diagnosis for Right Eyelid Swelling
Single Most Likely Diagnosis
- Blepharitis: This is an inflammation of the eyelids that can cause swelling, tenderness, and soreness, especially if it becomes infected. The symptoms described, such as soreness and tenderness to the touch, are common in blepharitis.
Other Likely Diagnoses
- Hordeolum (Stye): A localized infection or inflammation of the eyelid margin involving hair follicles of the eyelashes or meibomian glands. It presents as a painful, tender nodule on the eyelid.
- Chalazion: A small bump on the eyelid due to a blocked oil gland. While often painless, if it becomes inflamed or infected, it can cause soreness and tenderness.
- Allergic Reaction: Allergies can cause eyelid swelling, which may be accompanied by itchiness and redness. The reaction could be to makeup, pollen, or other environmental allergens.
- Insect Bite: A bite from an insect can cause localized swelling, redness, and soreness, especially if there's an allergic reaction to the bite.
Do Not Miss Diagnoses
- Orbital Cellulitis: An infection of the tissues surrounding the eye, which can cause eyelid swelling, pain, and tenderness. It's a serious condition that requires prompt antibiotic treatment.
- Angioedema: A condition characterized by rapid swelling of the dermis, subcutaneous tissue, mucosa, and submucosal tissues. It can be life-threatening if it involves the airways.
- Herpes Zoster (Shingles): If the eyelid swelling is accompanied by a rash or blisters, herpes zoster should be considered, especially in older adults or those with compromised immune systems.
Rare Diagnoses
- Sarcoidosis: A condition that can cause inflammation in various parts of the body, including the eyes. It might lead to eyelid swelling among other symptoms.
- Wegener's Granulomatosis (Granulomatosis with Polyangiitis): A rare autoimmune disorder that can affect various organs, including the eyes, and cause a range of symptoms including eyelid swelling.
- Thyroid Eye Disease: Associated with Graves' disease, it can cause eyelid swelling, among other eye symptoms, due to autoimmune inflammation.
