Differential Diagnosis for 25 yo male with eye injection and crusty eyelid
- Single most likely diagnosis
- Blepharitis: This condition is characterized by inflammation of the eyelids, often resulting in redness, swelling, and a crusty appearance. It's a common condition that can be caused by poor eyelid hygiene, allergies, or bacterial infections, making it a likely diagnosis for a young adult presenting with these symptoms.
- Other Likely diagnoses
- Conjunctivitis (Pink Eye): This is an infection or inflammation of the outer membrane of the eyeball and the inner eyelid. It can be caused by viruses, bacteria, or allergens and is known for causing redness, itching, and discharge, which could lead to a crusty eyelid.
- Dry Eye Syndrome: Although less likely to cause a crusty eyelid directly, severe cases can lead to inflammation and increased risk of infections, which might result in similar symptoms.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Orbital Cellulitis: A serious infection of the tissues surrounding the eye, which can lead to severe complications, including vision loss and spread of infection to other parts of the body. Symptoms can include redness, swelling, and discharge, making it crucial not to miss.
- Keratitis: An infection of the cornea, which can be caused by bacteria, viruses, or fungi. It's a medical emergency that requires prompt treatment to prevent permanent vision loss.
- Rare diagnoses
- Trachoma: A bacterial infection of the eye caused by Chlamydia trachomatis. It's rare in developed countries but can cause chronic keratoconjunctivitis, leading to scarring and vision loss if not treated.
- Erythema Multiforme: A skin condition that can affect the eyes, causing inflammation and potentially leading to symptoms like crusty eyelids. It's often associated with infections or medication reactions.
