Differential Diagnosis for Red Lower Eyelid in a Baby

  • Single most likely diagnosis
    • Conjunctivitis: This is a common condition in babies, often caused by a viral or bacterial infection, which can lead to redness and inflammation of the eyelid.
  • Other Likely diagnoses
    • Blepharitis: Inflammation of the eyelids can cause redness, itching, and swelling, and is relatively common in infants.
    • Eczema (Atopic Dermatitis): Babies with eczema may experience redness and irritation on their eyelids due to allergic reactions or skin sensitivity.
    • Blocked Tear Duct: A common condition in newborns where the tear duct is blocked, leading to excessive tearing, redness, and inflammation of the eyelid.
  • Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
    • Orbital Cellulitis: A serious bacterial infection of the tissues surrounding the eye, which can cause redness, swelling, and pain, and requires prompt medical attention.
    • Gonococcal Ophthalmia Neonatorum: A rare but serious condition caused by a bacterial infection, which can lead to blindness if left untreated.
  • Rare diagnoses
    • Herpes Simplex Virus (HSV) Infection: A rare but serious condition that can cause redness, swelling, and pain in the eyelid, and requires prompt medical attention.
    • Congenital Glaucoma: A rare condition that can cause redness, tearing, and sensitivity to light in one or both eyes, and requires prompt medical attention to prevent vision loss.
