@rajab Hello, Please talk to your doctor immediately as an eye infection along with serious symptoms including visual changes, severe headache, fever, nausea, swelling around the eyes, and difficulty breathing needs immediate care. Eye infections are almost always caused by either a virus or bacterial infection. Viral eye infections and very mild bacterial infections often resolve on their own. If he has a bacterial eye infection that does not resolve quickly, your health care provider may prescribe antibiotic ointment or drops. Thanks!
