Objectives: Microbial Diseases of the Eye
For each microbial disease listed give the following if applicable.
Diseases:
|
The mucous membrane lining the eyelid and covering the eyeball is the conjunctiva.
Conjunctivitis is caused by several bacteria and can be transmitted by improperly disinfected contact lenses.
Bacterial microbiota of the eye usually originate from the skin and upper respiratory tract.
Neonatal gonorrheal ophthalmia is caused by the transmission of Neisseria gonorrhoeae from an infected mother to an infant during its passage through the birth canal.
All newborn infants are treated with silver nitrate, tetracycline,or erythromycin to prevent the growth of Neisseria and Chlamydia infection.
Inclusion conjunctivitis is an infection of the conjunctiva cause by Chlamydia trachomatis. It is transmitted to infants during birth and is transmitted in unchlorinated swimming water.
In trachoma, which is caused by C. trachomatis, scar tissue forms on the cornea.
Trachoma is transmitted by hands, fomites, and perhaps flies.
Trachoma Lesions
Inflammation of the cornea is called keratitis.
Herpetic keratitis causes corneal ulcers. The etiology is HSV-1 that invades the central nervous system and can recur.
Trifluridine is an effective treatment for herpes keratitis.
Acanthamoeba protozoa, transmitted via water, can cause a serious form of keratitis.
