Conjunctivitis* is an inflammation of the conjunctiva, which is a thin transparent layer covering the surface of the inner eyelid and a portion of the front of the eye. There are three main types of conjunctivitis namely: infectious, allergic and chemical. This eye condition can affect patients of all ages including children.
The cause of infectious conjunctivitis, commonly known as "pink eye" is either a contagious virus or bacteria. If a patient has allergies to pollen, cosmetics, animals or fabrics, this can bring on the allergic form. Irritants like air pollution, noxious fumes and chlorine in swimming pools may cause the chemical form of conjunctivitis.
The common symptoms of conjunctivitis are red eyes, inflamed inner lids, watery eyes, blurred vision and sandy or scratchy feeling in the eyes. There may be a pus-like discharge around the eyelids if the patient has contracted the infectious form.
Caution should be taken to avoid spreading infectious conjunctivitis to others. The hands should be kept away from the eyes and thoroughly washed before and after applying eye medication. Also, avoid sharing towels, washcloths, cosmetics or eye drops with others. Small children, who may forget these precautions, should be kept away from school, camp and the swimming pool until the condition is cured.
An optometric comprehensive eye health examination can determine if conjunctivitis has developed and treated if necessary.
