Ocular Infection

What is ocular infection?

A variety of bacteria populate the eye and those that are usually present are call “normal flora” while others may be introduced via contaminated adjacent skin or through the sinuses or oral cavity. These “non-normal flora” bacteria are usually prevented from causing infection by the eye’s 4 natural defense mechanisms: the bony orbits, eyelids, lashes and tears.

What causes ocular infection?

Bacteria can cause ocular infections when the natural defense mechanisms of the eye fail. Once a pathogen gains entry to the body it faces the body’s immune system, a complex system of cellular (cell-based) and humoral (fluid based) components distributed throughout the body that identifies and aims to destroy the invading pathogens.
