Differential Diagnosis for 3 Week Old with Gunk Coming Out of Eyes
- Single Most Likely Diagnosis
- Conjunctivitis (likely chemical or infectious): This is the most common cause of eye discharge in newborns, often due to exposure to bacteria during birth or chemical irritation from the eye drops given at birth to prevent the spread of gonorrhea and chlamydia.
- Other Likely Diagnoses
- Nasolacrimal duct obstruction: This condition is common in newborns and can cause tearing and discharge due to the blockage of the tear duct.
- Infectious conjunctivitis (bacterial or viral): Similar to the single most likely diagnosis, but considering a broader range of infectious causes.
- Allergic conjunctivitis: Though less common in newborns, it could be a consideration, especially if there's a family history of allergies.
- Do Not Miss Diagnoses
- Gonococcal conjunctivitis: A serious and vision-threatening condition if not promptly treated, caused by Neisseria gonorrhaeae.
- Chlamydial conjunctivitis: Another serious condition that requires prompt treatment to prevent long-term vision and health consequences.
- Herpes simplex virus (HSV) conjunctivitis: Can lead to serious complications, including coruralardisease and potentially life-threatening neonatal herpes if not recognized and treated.
- Rare Diagnoses
- Congenital glaucoma: Though rare, it can present with tearing, discharge, and eye enlargement.
- Dacryocystitis: An infection of the lacrimal sac, which can occur in newborns, especially if there's an underlying nasolacrimal duct obstruction.
- Leukocoria-associated conditions (e.g., retinoblastoma): While extremely rare and not typically presenting with discharge, any abnormal appearance of the eyes in a newborn should prompt a thorough evaluation to rule out serious conditions.
