Differential Diagnosis for Newborn with Yellow Eye Discharge
Single Most Likely Diagnosis
- Chemosis and Conjunctivitis due to Blocked Tear Duct: This condition is common in newborns due to the tear ducts not being fully open, leading to accumulation of tears and discharge. The yellow color of the discharge is indicative of a bacterial infection, which can secondarily infect the conjunctiva.
Other Likely Diagnoses
- Neonatal Conjunctivitis (Ophthalmia Neonatorum): Caused by exposure to pathogens during birth, such as Chlamydia trachomatis or Neisseria gonorrhoeae, this condition presents with eye discharge and can be serious if not treated promptly.
- Viral Conjunctivitis: Herpes simplex virus (HSV) can cause conjunctivitis in newborns, presenting with yellow discharge, although it's less common than bacterial causes.
Do Not Miss Diagnoses
- Gonococcal Conjunctivitis: Although less common, this condition can lead to severe consequences, including corneal perforation and blindness if not treated immediately with appropriate antibiotics.
- Herpes Simplex Virus (HSV) Keratoconjunctivitis: HSV infection can have severe implications, including the potential for central nervous system involvement and long-term vision loss, making prompt diagnosis and treatment critical.
Rare Diagnoses
- Congenital Glaucoma: While rare, congenital glaucoma can present with excessive tearing and discharge, among other symptoms like photophobia and eye enlargement.
- Dacryocystitis: Infection of the lacrimal sac can occur in newborns, especially if there's a blockage of the nasolacrimal duct, leading to discharge and potentially serious complications if not addressed.
