Bacterial
Conjunctivitis
The
symptoms of bacterial conjunctivitis are a thick discharge from the eye
that contains pus, and crusty eyelids that may require prying apart after
sleeping. The underside of the eyelid turns deep red and feels very
sore. The white part of the eye also turns red and bloodshot.
Bacterial conjunctivitis is common in young children who's hand washing
skills haven't quite developed.
Viral
Conjunctivitis
Viral conjunctivitis is more common in adults than children. Unlike
the bacterial infection, viral conjunctivitis can originate in the eye,
or start as a virus causing a cold or sore throat. The discharge
is usually less sticky than bacterial conjunctivitis. The conjunctiva
under the eyelids is red, and often has small raised bumps. The eyes
hurt and turn red. Viral conjunctivitis can not be cured with antibiotics
and usually goes away after a few days.
Fungal
Conjunctivitis
Fungal infections of the conjunctiva occur especially in people whose immune
system isn't working properly, such as someone with cancer or AIDS or someone
taking immune supressants, such as after an organ transplant. Fungal
conjunctivitis is very hard to diagnose yourself and can be very dangerous.
If you have any symptoms of conjunctivits while being treated for cancer
or AIDS, or if you are on an immune suppressant, see your doctor immediately.
Allergic
Conjunctivitis
Allergic conjunctivitis is pinkeye caused by allergy. Unlike the
painful infections of the conjunctiva, allergic reactions itch. The
sclera
may become red, but the underside of the eyelid remains pale. Commonly,
allergic reactions also include a watery discharge, coughing, wheezing,
sneezing, and other allergy symptoms. This may be treated with antihistamines
or eye drops that block allergic reactions.
Giant
Papillary Conjunctivitis
Giant Papillary Conjunctivitis (GPC) often appears in in people who wear
conventional soft contact-lenses and is a chronic allergic reaction of
the conjunctiva on the upper eyelid. The conjunctiva can also be
irritated by a surgical suture or other foreign object in the eye. This
condition is not harmful to your vision or the health of the eye.
Itching, a white mucus discharge, contacts that feel dry and move around
when you blink, and a milky ringlike stain on the contact-lens that cannot
be removed are symptoms of GPC. When inspected under a microscope,
one sees that the inside of the eyelid is covered with tiny grey bumps,
papillae, that are only "giant" when compared with similar disorders.
