- Conjunctivitis is a condition
in which the conjunctiva covering the white part of the eye
becomes inflamed, red, and irritated. Anything that irritates or
infects the conjunctiva can cause conjunctivitis. Viral and allergic
causes tend to have clear or "white eye discharge."
Bacterial causes, e.g., staphylococcus, tend to have yellow
or green eye
discharge.

- Clear discharge, sudden onset -- usually Viral Conjunctivitis
("Pink Eye")
- Clear discharge, seasonal, or
related to environment-allergic
- Colored discharge -- usually
bacterial (can still occasionally be viral) -- cultures may
be done
- Sicca (dry) Eyes -- diagnosed by
Schirmer's test
|
|
- Viral (pink eye) -- none, but wash
hands cautiously and avoid touching eye, as it is very
contagious
- Gonorrhea --
Ceftriaxone by injection
- Chlamydia --
Doxycycline, Erythromycin, Azithromycin
- Bacterial causes -- antibiotic eye drops, e.g., Polytrim
- Allergic Eye -- topical lodoxamide,
Naphcon A eye drops, other allergy eye drops
- Dry Eyes -- artificial tear drops
- Treatment precaution:
- Some antibiotic eye drop preparations contain
corticosteroids. Corticosteroids can be helpful in some
infections, but can make others worse. In most instances,
drops containing corticosteroids should only be prescribed
by an ophthalmologist (medical doctor who specializes in eye
diseases).

- Contact lens use increases the risk of bacterial conjunctivitis. Extended wear contacts have the highest risk. Use proper sterile techniques when handling your lenses. Follow instructions on how to clean your lenses carefully.
