Conjunctivitis -------------- General Information The conjunctiva is the pink tissue that lines the inner surface of the eyelids and covers the front portions of the eyeball, except the clear, transparent cornea. It is a protective layer that contains special glands whose secretions help maintain normal eye health. Conjunctivitis is used to describe the conjunctiva when it becomes reddened, congested and painful. It may occur in one or both eyes, depending upon the cause. Causes of conjunctivitis include foreign matter, chemicals, bacteria, viruses or other germs, polluted water or smoke. Other causes may be due to birth defects, serious internal diseases and allergic reactions. Important Points in Treatment 1. Laboratory tests, including blood cell counts, conjunctival scrapings and cultures, may be needed to help determine the cause and an effective treatment. 2. Attempts should be made to prevent further irritation to your pet's eyes from such things as contaminated water, soap, dust, sprays, smoke, trauma, etc. Notify the Doctor if Any of the Following Occur: * Your pet shows continued signs of pain or discomfort. * You cannot apply medication as directed. * The condition appears to worsen.
