Conjunctivitis refers to any inflammatory condition of the membrane that lines the eyelids and covers the exposed surface of the eye. It is the most common cause of “pink eye.” Conjunctivitis is commonly caused by bacteria and viruses. Our office utilizes the RPS adenoviral test in order to determine the type of conjunctivitis you have. We then take the appropriate steps to treat the particular type of “pink eye.” Allergic conjunctivitis, on the other hand, can be caused by exposure to certain irritants and is often seasonal. This condition can be treated long term with drugs such as antihistamines and mast cell stabilizers.
