Differential Diagnosis for Swollen Eyes
- Single most likely diagnosis
- Allergic reaction: Although the patient denies any allergies, an allergic reaction could still be a possible cause, especially given the sudden onset of symptoms and the fact that the swelling has decreased with the application of an ice pack. The aggravation by air could suggest an environmental allergen.
- Other Likely diagnoses
- Angioedema: This condition is characterized by the rapid swelling of the skin and mucous membranes, which could explain the patient's tender eyelids and swollen eyes. The absence of itching and redness does not rule out angioedema.
- Blepharitis: This is an inflammation of the eyelids that can cause swelling, tenderness, and sticking of the eyelids together, especially in the morning. However, the patient's symptoms started in the evening, which makes this diagnosis less likely.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Orbital cellulitis: This is a serious infection of the tissues surrounding the eye that can cause swelling, redness, and pain. Although the patient denies redness, this condition requires prompt medical attention to prevent serious complications.
- Thyroid eye disease: This condition can cause swelling of the eyelids and tissues around the eye, and can be associated with a headache. Although the patient is on metformin, atorvastatin, and lisinopril-hydrochlorothiazide, which does not directly suggest a thyroid condition, it is still a possibility that should not be missed.
- Rare diagnoses
- Superior vena cava syndrome: This is a rare condition that can cause swelling of the face and eyes due to obstruction of the superior vena cava. However, this would typically be associated with more systemic symptoms and is unlikely given the patient's presentation.
- Erythema multiforme: This is a rare skin condition that can cause swelling and blistering of the skin and mucous membranes, including the eyes. However, the patient's symptoms do not fully align with this condition, and it is considered rare.
