Differential Diagnosis for Left Eye Lid Pain and Swelling
Single Most Likely Diagnosis
- Blepharitis: This is an inflammation of the eyelids that can cause pain, swelling, and redness. It is a common condition and can be acute or chronic. The symptoms described, such as eyelid pain and swelling, are consistent with blepharitis, especially if the patient has a history of similar episodes or other symptoms like itching or burning.
Other Likely Diagnoses
- Hordeolum (Stye): A localized infection or inflammation of the eyelid margin involving hair follicles of the eyelashes (external hordeolum) or meibomian glands (internal hordeolum). Symptoms include pain, swelling, and redness, which match the patient's presentation.
- Chalazion: A small bump on the eyelid due to a blocked oil gland. While it might not be as painful as a stye, it can cause swelling and discomfort, fitting the patient's symptoms.
- Conjunctivitis: Inflammation or infection of the outer membrane of the eyeball and the inner eyelid. It can cause redness, itching, and swelling, which could be perceived as eyelid pain and swelling.
Do Not Miss Diagnoses
- Orbital Cellulitis: An infection of the soft tissues surrounding the eye, which can lead to serious complications if not treated promptly. Symptoms can include swelling, redness, and pain around the eye, making it a critical diagnosis not to miss.
- Herpes Zoster Ophthalmicus: Shingles affecting the eye, which can cause severe pain, swelling, and potentially lead to complications like vision loss if not treated early.
Rare Diagnoses
- Dacryocystitis: Inflammation of the lacrimal sac, usually due to a blockage of the nasolacrimal duct. It can cause pain, swelling, and redness over the lacrimal sac area, which might be perceived as eyelid swelling.
- Sarcoidosis: A condition that can affect various parts of the body, including the eyes, causing inflammation and potentially leading to symptoms like eyelid swelling.
- Wegener's Granulomatosis (Granulomatosis with Polyangiitis): A rare autoimmune disorder that can affect many parts of the body, including the eyes, and cause a variety of symptoms, including eyelid swelling and pain.
