Conjunctivitis or “pink eye”, is the swelling or inflammation of the conjunctiva. The thin, transparent layer of tissue that lines the inner surface of the eyelid and covers the white part of the eye.
Pink eye is most often caused by a viral infection. It also can be caused by a bacterial infection, an allergic reaction or — in babies — an incompletely opened tear duct. Though pink eye can be irritating, it rarely affects your vision.
The infection will usually clear up in 7 to 14 days without treatment and without any long-term consequences. However, in some cases, viral conjunctivitis can take 2 to 3 weeks or more to clear up.
Ciprofloxacin belongs to a class of drugs called quinolone antibiotics. It works by stopping the growth of bacteria. This medication treats only bacterial eye infections.
