your eye or eyes are red, water, sting, itch, discharge or you have a foreign
body sensation, it may well be that you have caught an eye infection.
An eye infection is an eye disorder caused by bacterial, viral, or fungal agents. The following text refers to the special case of conjunctivitis, even more specifically, to infectious conjunctivitis.
Conjunctivitis is an inflammation of the conjunctiva (a thin transparent tissue covering the white part of the eye and the inside of the eyelids). It is often due to an infection - bacterial or viral - an allergic reaction or sometimes caused by a foreign body in the eye. It usually affects both eyes at the same time, but it may also occur in one eye only. Normally conjunctivitis is not very painful.
Infectious conjunctivitis can be caused by bacteria, such as staphylococci, streptococci and pneumococci, and, especially in children, by bacteria belonging to the haemophilus group. Also viruses are typical causes of infectious conjunctivitis.
further examination please consult your ophthalmologist, who can diagnose
infectious conjunctivitis by its symptoms and appearance. When examining the
eye with a slit lamp, the doctor may find conjunctival redness (the white part
of the eye is bloodshot, more in the edges than in the middle) and that pus-like,
white or yellow discharge is present. By the way: a slit lamp is an instrument
that allows inspecting the eye under high magnification. If the disease lasts
for a long time, samples of infected secretions may also be analyzed to
identify the infecting organism. Blood is not routinely used in diagnosing eye
conjunctivitis (see allergy) may sometimes be confused with infectious conjunctivitis.
In allergic conjunctivitis there is less discharge (the discharge is typically
clear and elastic) and the symptoms last significantly longer.
doctor can recommend the right treatment, but everyone who has conjunctivitis
should follow one simple rule: don't
touch or rub your eyes!
Eye infection caused by bacteria is usually treated with (topical, i.e. local)
antibiotics, more specifically, with antibiotic eye drops and ointments, normally
taken for 3-5 days. If the infection does not disappear within this period
of time, you should consult your ophthalmologist again.
