Infection/inflamation

Inflammation

When the eye has been damaged, it  becomes red and swollen in appearance.  Things which can cause an inflammation include infection, allergy, mechanical injury, foreign body.    When a tissue becomes inflamed we add the suffix -itis to the anatomical name, for example, the pink fleshy area of the eye, under the eyelid is called the conjunctiva and when it becomes inflamed it is called 'conjunctivitis'.  Symptoms of inflammation are redness, swollen tissue, discharge

Infection

An infection occurs when a micro-organism invades the body.  The most common micro-organisms are bacteria and viruses.  You can get an infection in numerous ways including from another person, from something you have touched or eaten, or even by your own naturally occuring micro-organisms getting out of control.  An inflammation reaction usually follows, but medication such as an antibiotic is usually required.  Please note, a virus can not be helped with an antibiotic

Common infections in the eye include conjunctivitis, blepharitis, keratitis, iritis
