What is conjunctivitis? |
|
|
The conjunctiva is a thin, transparent, mucosal membrane that lines the
inner eyelid and the visible portion of the eye. An inflammation of this layer is
termed conjunctivitis. There are 3 main types of conjunctivitis:
- Infectious - commonly referred to as "pink eye"; caused by
virus or bacteria
- Allergic - produced by allergic reaction to allergens such
as pollen, animal dander, fabrics, etc.
- Chemical - resulting from reactions to such irritants as noxious
fumes, chlorinated swimming pools, and air pollution.

Treatment |
|
|
One way to avoid allergic or chemical conjunctivitis is to simply avoid
the source of the allergens or irritation. This may be easier said than done and
in some cases be just plain impractical. Other remedies include prescription or
over-the-counter eye drops to increase lubrication between the eyelid and the surface
of the eye. Antibiotic drops may also be prescribed to reduce swelling and irritation.

Prevention |
|
|
Minimize contact with your eyes. If it is necessary to touch the eye
or the surrounding area, always wash your hands thoroughly. Also, DO NOT share washcloths,
towels, cosmetics, or eye drops with others.
