Differential Diagnosis for Left Upper Eyelid Swelling
- Single most likely diagnosis
- Allergic conjunctivitis: The patient's symptoms of eyelid swelling and feeling of something in the eye, along with the use of allergy drops, suggest an allergic reaction. The recent exposure to a campfire could have triggered the allergy, and the lack of improvement with allergy drops may indicate a need for a different treatment approach.
- Other Likely diagnoses
- Irritant conjunctivitis: Exposure to particulates from the campfire could have caused irritation and inflammation of the conjunctiva, leading to eyelid swelling and discomfort.
- Blepharitis: This condition involves inflammation of the eyelids and can cause swelling, redness, and irritation, which may be exacerbated by exposure to irritants like campfire smoke.
- Dry eye syndrome: The feeling of something in the eye and irritation could be symptoms of dry eye syndrome, which may be worsened by environmental factors like smoke exposure.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Orbital cellulitis: Although the patient denies fever and significant pain, orbital cellulitis is a serious infection that can cause eyelid swelling and requires prompt treatment to prevent complications.
- Angioedema: This condition can cause rapid swelling of the eyelids and face, and while it is less likely, it is a medical emergency that requires immediate attention.
- Rare diagnoses
- Thyroid ophthalmopathy: This condition can cause eyelid swelling and retraction, but it is less likely given the acute onset and lack of other symptoms like vision changes or diplopia.
- Sarcoidosis: This autoimmune disease can cause uveitis and eyelid swelling, but it is a rare condition that would require further evaluation and testing to diagnose.
