Conjunctivitis, also known as pink eye, is the inflammation or infection of the outer membrane of the eyeball and the inner eyelid.
The white of the eye (sclera) is covered by a thin, filmy membrane called the conjunctiva that produces mucus to coat and lubricate the surface of the eye. It normally has fine blood vessels in it, which can be seen when you look closer. When the conjunctiva becomes irritated or inflamed, the blood vessels that supply it can enlarge and become much more prominent, and the eye turns red. There are three main types of conjunctivitis.
Bacterial Conjunctivitis
Bacterial infections, such as strep throat, cause a red eye associated with considerable amounts of puss. If the amount of discharge from the eye is heavy, acute infection is likely, and an immediate visit to Indiana Eye Clinic is advisable. Some bacterial infections are more chronic and may produce little or no discharge except for some mild crusting of the eyelashes in the morning.
Viral Conjunctivitis
Viruses are also common causes of conjunctivitis. Some viruses produce red eyes, a sore throat and runny nose. Others may infect only one eye. Viral conjunctivitis usually produces a watery discharge and lasts from one to two weeks.
Infectious conjunctivitis can be quite contagious. Contact with patient tears through used towels or linens should be avoided. Consistent hand washing after contact with the patient helps to prevent the spread of infection.
Allergic Conjunctivitis
Allergies also tend to cause a type of conjunctivitis that produces a discharge. Some allergies like hay fever make the eyes very itchy, while others may produce a chronic redness. Environmental irritants such as smoke or fumes may also cause conjunctivitis. Any type of conjunctivitis aggravated by the dryness of the eyes.
It is important to know the symptoms of conjunctivitis to avoid confusing it with other more serious eye diseases that can lead to blindness. That’s why getting a red eye examined by a doctor at Indiana Eye Clinic is always the best route. This is especially true if pain, blurred vision or severe light sensitivity are present. These symptoms are not typically found in simple conjunctivitis and may signal the presence of glaucoma, an ulcer or inflammation of the inside of the eye.
