Conjunctivitis, aka "pink eye",
is a very common condition characterized by inflammation of the
conjunctiva. There are many causes, the most common of which can
be grouped into two broad categories: microorganisms (viruses and
bacteria, for example) and allergic reactions (medications and pollen,
for example). A virus is the most common cause of pink eye.
Typical
symptoms of conjunctivitis include redness of the eyes, tearing or
discharge, general discomfort in the eyes, and the feeling that there
is "sand" in the eye. In cases of allergic conjunctivitis itching
is usually the major complaint, although other symptoms may also be
present.
The most
common sign in pink eye is redness over the "whites" of the eyes.
There are certain signs that help the eye doctor to determine the
cause. For example, does the conjunctivitis involve one or both
eyes? Viral or bacterial conjunctivitis usually starts with one
eye and may or may not involve the other eye several days later.
Is there clear fluid or discharge draining from the eye?
Yellow-green discharge suggests that there may be a bacterial
cause. Is there enlargement and tenderness of the lymph node just
in front of the ear on the same side as the affected eye? This
often occurs in viral conjunctivitis. Is there involvement of the
cornea? Small areas of corneal involvement may indicate a viral
cause and lead to sensitivity to light.
The most
important thing that patients with these symptoms can do is practice
good hygiene. Frequent hand washing, keeping the fingers out of
the eyes, and not sharing linens are very important to prevent the
spread of the contagious forms of conjunctivitis to other people.
Conjunctivitis
accounts for a large number of patient visits to emergency rooms as
well as to medicine and eye clinics. It is important to notify
your doctor if any of the following symptoms are associated with pink
eye: loss of vision, drainage, eye pain, failure to get better within
1-2 weeks, or worsening of symptoms after seeing your doctor.
The
treatment of conjunctivitis depends on the cause. The most common
cause is viral, and the vast majority of cases will heal on their own
with no treatment. Therefore, antibiotics are usually not needed
to treat pink eye. Artificial tears and cool compresses may
provide symptomatic relief in viral cases. Ophthalmologists may
decide to treat with steroid eye drops in some instances. There
are certain viruses that do have specific treatment; for example,
herpes simplex virus is often treated with antiviral eye drops.
There are also eye drops that are effective in treating allergic
conjunctivitis.
In
uncomplicated cases, patients can expect their symptoms to resolve
completely after 1-2 weeks as the conjunctivitis heals. Patients
with allergic conjunctivitis can usually find relief from their
symptoms with prescription eye drops, although it may take several
weeks to find the most effective medications. There may also be
chronic low grade symptoms or seasonal flare-ups, especially if the
conjunctivitis is related to substances in the air, such as pollen.
