Differential Diagnosis for Dryness and Redness around Newborn Eyes
- Single most likely diagnosis
- Conjunctivitis of the newborn (ophthalmia neonatorum): This condition is a common cause of redness and discharge in newborns, often due to exposure to pathogens during birth. The dryness could be secondary to the inflammation.
- Other Likely diagnoses
- Blocked tear duct (nasolacrimal duct obstruction): This is a common condition in newborns where the tear duct is blocked, leading to excessive tearing and possibly redness due to secondary infection or irritation.
- Allergic conjunctivitis: Though less common in newborns, allergic reactions to environmental factors could cause redness and dryness around the eyes.
- Irritant conjunctivitis: Exposure to irritants such as soap, shampoo, or other chemicals could cause redness and dryness.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Gonococcal conjunctivitis: A severe infection caused by Neisseria gonorrhoeae, which can lead to corneal perforation and blindness if not treated promptly.
- Chlamydial conjunctivitis: Caused by Chlamydia trachomatis, this infection can lead to serious complications if not treated, including pneumonia and long-term vision problems.
- Herpes simplex virus (HSV) conjunctivitis: HSV infection can cause severe ocular and systemic disease in newborns, making prompt diagnosis and treatment critical.
- Rare diagnoses
- Congenital glaucoma: A rare condition that can cause redness, tearing, and sensitivity to light due to increased intraocular pressure.
- Sjögren's syndrome: An autoimmune disorder that can cause dry eyes, though it is extremely rare in newborns.
- Erythema multiforme: A skin condition that can affect the eyes, causing redness and irritation, though it is uncommon in newborns.
