Differential Diagnosis for Swollen Eyes in an 80-Year-Old Male
Single Most Likely Diagnosis
- Allergic Reaction: Given the age and the presentation of swollen eyes, an allergic reaction to environmental factors, medications, or substances is a common and likely cause. This can be due to a new exposure or a long-standing allergy.
Other Likely Diagnoses
- Blepharitis: An inflammation of the eyelids that can cause swelling, often associated with skin conditions or infections.
- Conjunctivitis: Inflammation or infection of the outer membrane of the eyeball and the inner eyelid, which can be viral, bacterial, or allergic in nature.
- Dry Eye Syndrome: Although more commonly associated with irritation and discomfort, severe cases can lead to swelling.
- Graves' Disease: An autoimmune disorder that can cause bulging of the eyes (exophthalmos) and swelling of the eyelids.
Do Not Miss Diagnoses
- Orbital Cellulitis: A serious infection of the tissues surrounding the eye, which can lead to severe complications if not promptly treated.
- Angioedema: A condition characterized by rapid swelling of the dermis, subcutaneous tissue, mucosa, and submucosal tissues, which can be life-threatening if it involves the airways.
- Temporal Arteritis: An inflammation of the blood vessels in the head, which can cause eye symptoms including swelling, and if untreated, can lead to blindness.
- Endocrine Disorders (e.g., Thyroid Ophthalmopathy): Certain endocrine conditions can cause eye swelling and other ocular symptoms.
Rare Diagnoses
- Wegener's Granulomatosis (Granulomatosis with Polyangiitis): A rare autoimmune disorder that can affect various parts of the body, including the eyes, causing swelling and other symptoms.
- Sarcoidosis: A condition in which inflammatory cells form lumps known as granulomas in various parts of the body, including the eyes, leading to swelling and other ocular symptoms.
- Amyloidosis: A group of diseases in which abnormal proteins (amyloid) accumulate in organs and tissues, potentially causing eye swelling among other symptoms.
- Lymphoma or Other Malignancies: Although rare, certain types of cancer can manifest with eye swelling as an initial symptom.
