Newborn conjunctivitis that presents with nonpurulent discharge is most consistent with which type?

• A. Chemical-induced conjunctivitis
• B. Bacterial conjunctivitis
• C. HSV conjunctivitis
• D. Gonococcal conjunctivitis

Answer: (A)

Newborn conjunctivitis presents with patterns that point to different causes, and the type of discharge is a key clue. Nonpurulent discharge is classic for chemical-induced conjunctivitis, which occurs very soon after birth—often within the first day or two—due to contact with maternal secretions or prophylactic eye drops. It tends to be mild, with redness and irritation but little or no pus, and it usually resolves within 24 to 48 hours without antibiotics. In contrast, bacterial conjunctivitis in newborns typically shows purulent discharge that is thick and may be yellow-green, with more noticeable eyelid swelling and redness. Gonococcal and chlamydial conjunctivitis are notable examples: gonococcal infection often presents with copious purulent discharge and rapid progression, while chlamydial conjunctivitis tends to appear a bit later and also involves mucopurulent discharge. HSV conjunctivitis can have mucopurulent discharge as well, but it is usually associated with vesicular skin lesions or dendritic keratitis and can be more invasive. So the nonpurulent, very early presentation aligns best with chemical-induced conjunctivitis.
