Common eye infections

Abstract

Not all red eyes are due to infections. Not all eye infections respond to antibiotic eye drops. Conjunctivitis is the most common eye infection. Most cases are viral and do not require antibiotic eye drops. Infectious keratitis is a cause of blindness. It is an emergency that requires specialist treatment. Infectious endophthalmitis is an emergency that has become more frequent with the use of intravitreal injections. Intravitreal antibiotics are needed to try and prevent visual loss.
