Bacterial conjunctivitis
Bacterial Conjunctivitis
Bacterial conjunctivitis (pronunciation: bak-TEER-ee-al kon-junk-tuh-VY-tis), also known as pink eye, is an infection of the conjunctiva (the outermost layer of the eye and the inner surface of the eyelids) caused by bacteria.
Etymology
The term "conjunctivitis" is derived from Latin, with "conjunctiva" referring to the part of the eye affected, and "-itis" indicating inflammation. The prefix "bacterial" specifies the cause of the inflammation.
Causes
Bacterial conjunctivitis is most commonly caused by Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. These bacteria can be spread through direct contact with an infected individual or by touching a surface contaminated by the bacteria and then touching the eyes.
Symptoms
Symptoms of bacterial conjunctivitis include redness in the white of the eye or inner eyelid, increased tearing, a thick yellow discharge that crusts over the eyelashes, especially after sleep, and an itchy or burning sensation in the eyes.
Treatment
Treatment typically involves the use of antibiotic eye drops or ointments prescribed by a healthcare professional. It is important to complete the full course of antibiotics to prevent recurrence of the infection.
