Non-infectious Chemical irritants such as silver nitrate can cause chemical<unk> , usually lasting 2–4 days. Thus, prophylaxis with a 1% silver nitrate solution is no longer in common use. In most countries, neomycin and chloramphenicol eye drops are used, instead. However, newborns can suffer from<unk>  due to reactions with chemicals in these common eye drops. Additionally, a blocked tear duct may be another noninfectious cause of<unk> . Infectious The two most common infectious causes of<unk>  are N. gonorrheae and Chlamydia, typically acquired from the birth canal during delivery. However, other different bacteria and viruses can be the cause, including herpes simplex virus (HSV 2), Staphylococcus aureus, Streptococcus pyogenes, and Streptococcus pneumoniae. Ophthalmia neonatorum due to gonococci (N. gonorrhoeae) typically manifests in the first 5 days after birth and is associated with marked bilateral purulent discharge and local inflammation. In contrast,<unk>  secondary to infection with C. trachomatis produces<unk>  3 days to 2 weeks after delivery. The discharge is usually more watery in nature (mucopurulent) and less inflamed. Babies infected with chlamydia may develop pneumonitis (chest infection) at a later stage (range 2–19 weeks after delivery). Infants with chlamydia pneumonitis should be treated with oral erythromycin for 10–14 days. Diagnosis is performed after taking swab from the infected conjunctivae.
