Conjunctivitis “Pink Eye”By: Laura Brown, Sarah Afiz, and Nick Olson P.1
Conjunctivitis Conjunctivitis is the inflammation of the conjunctiva, which is the clear membrane covering the sclera (white part of eye) and interior lining of eyelids. Conjunctivitis only occurs in the eye. The inflammation of the conjunctiva cause the eye’s blood vessels to dilate, resulting in the reddish appearance.
Forms of Conjunctivitis 5 different types of Conjunctivitis1. Bacterial Conjunctivitis- caused by bacteria2. Viral Conjunctivitis- often associated with the common cold, caused by the adenovirus3. Chlamydia Conjunctivitis- caused by sexually transmitted infections4. Allergic Conjunctivitis- caused by pollens, dust5. Reactive Conjunctivitis- caused by chemicals such as chlorine in swimming pools, shampoos and other foreign objects.
People Affected Conjunctivitis can affect any age person of either sex. It also can affect any race. It is very serious if it occurs in an infant. An infant can contract it while going through the birth canal. It is also a common ailment in pre-schools and elementary schools due to the easy transmission of the virus.
SymptomsThe symptoms of conjunctivitis are varied depending on the cause of it: Redness of the white area of the eye Increased tears Thick yellow discharge that when dries it crusts over the eyelashes Itchy eyes or Burning sensation Blurred vision Increased sensitivity to light/ brightness of sun
Disease Appearance Conjunctivitis can occur at any time of the year and any time of the day. It is noticed most prominently in the early mornings when eyes are closed shut from the mucus. Allergy induced occurs primarily during the heightened hay fever season. Chemical induced occurs primarily in summer due to increased pool usage. Cases increase during the school year due to close proximity with so many children in daycare and schools and lack of proper hygiene.
Incubation It normally starts in one eye and spreads to the other eye in a day or two This disease is asymmetrical, meaning it can affect one eye more than the other Incubation Period for Pink Eye will vary depending on whether it is caused by bacteria or a virus. Viral infection: from 12 hours to 3 days later, symptoms will appear. Bacterial infection: symptoms display one to three days after transmission.
TreatmentsTreatments vary depending on type: Bacteria: treated with antibiotics, in the form of eye drops (Fluorometholone, Tobramycin), ointments, or pills. In all cases, if pink eye continues, a Dr. should be consulted. Recommended to throw contact lenses away and insert new ones when the pink color is gone. If left untreated, bacterial conjunctivitis can cause scars on eye’s surface leading to permanent damage and vision loss There is no lasting effects if it is treated properly
