The suffix “itis” appears at the end of a lot of medical words and means inflammation. Therefore conjunctivitis means inflammation of the conjunctiva, a layer of the eye. There are three types of conjunctivitis. Most people automatically think of a bacterial cause and want antibiotic treatment for this however this is the least common type. Allergic conjunctivitis is the most common followed by viral then bacterial.

Chloramphenicol antibiotic drops can be obtained by the pharmacist for patients two years and above. These are used as one drop every 2 hours initially then every 4-6 hours for up to 5 days. The eye can only hold one drop so any more is a waste. Any time an eye drop is used it is a good idea to place a finger on the inner corner of the eye for a minute to stop the drop draining straight out and down the back of the nose. Wash hands really well before and after using eye drops and be careful not to touch the bottle on to the eye or it can become contaminated.
If there are symptoms such as pain, loss of vision, cloudy eyes, reduced eye movement, changed pupil size, contact lens wear or possible foreign body a Doctor or optometrist should be seen.
