You examine a 3 day old newborn brought in because of the eye finding shown above. The baby was born at home without any prenatal care.

Challenge: In the hospital newborns usually receive what for prophylaxis against this disease?

erythromycin eye ointment to prevent chlamydia (typed while nursing my own newborn, or I guess not so new anymore)

So I did a little reading - neonatal conjunctivitis from Chlamydia and Gonorrhea look pretty much the same but the diagnosis is based on the timeline - Gonorrhea if 2-3 days old; Chlamydia if 5-12 days old (or even longer).

I intended this case to be Gonoccocal conjunctivitis, but the symptoms are the same as Chlamydia.

Trachoma is caused by Chlamydia and I think it's a complication of untreated conjunctivitis.

This is an image showing gonoccocal conjunctivitis which can present with mild hyperemia to severe eyelid edema with diffuse chemosis and profuse purulent exudate. The infectious organism is Neisseria gonorrhoeae and untreated infections can lead to vision loss. Treatment is ceftriaxone; prophylaxis is silver nitrate, erythromycin, or tetracycline.
