Germs can penetrate the eyes, but bacterial infections in the eye are relatively rare. Why is this?

Blinking crushes bacteria that try to enter the eye.
Eyelashes act as shields preventing germs from entering the eye.
Tears, which constantly wash over the eye, contain an anti-bacterial enzyme.
The number of bacteria that can actually infect the eye is quite small.
----------

Blinking does not crush bacteria. Bacteria are too small and can slip into the eye even when it's closed.
Eyelashes might shield larger debris from entering the eye but not bacteria. Again... they're too small, and eye infections are usually spread by the fingers anyway.
Tears are probably the best bet to why eye infections are rare. I'm not sure about the anti-bacterial enzyme although I don't doubt this concept, but salinity and the fact that they're constantly flushing and draining the eye's surface probably has something to do with it also.
I'm sure there are a plethora of bacteria that can infect the eye. Our bodies are just built to defend themselves against them since we evolved with these bacteria.  (+ info)

Can doxycycline treat bacterial infections of the eye?


Is doxycycline systemic? Can it treat infections anywhere in the body, including the eyes if one had bacterial conjunctivitis?
----------

Question #1: Ciprofloxacin & trimethoprim-polymyxin are often used. For inclusion conjunctivitis, oral azithromycin, doxycycline or erythromycin are used. Gonococcal conjunctivitis may be treated with an injection of ceftriaxone. And adenoviral onjunctivitis is treated in a another way.


Question #2: Doxy is systemic if taken orally. Naturally, topical doxy is not.

Question #3: Although doxy is a broad-spectrum antibiotic in the tetracycline family, the trend now is toward targeted therapy using narrow-spectrum antibiotics. If you have doxy lying around, discard it. There are more kinds of conjunctivitis than bacterial, so one would need to be diagnosed first. Only bacterial conjunctivitis is treated with an antibiotic.  (+ info)

how does the eye resist bacterial infections?


i know that the eyelids help protect the eye from bacterial infections

but when your eyes are exposed and the eyelids are open, how to the eyes resist bacterial infections?

(any websites would be helpful)
----------

Firstly, the eye has good reflexes, for example, the blink reflex. So when something comes close to your eye you blink immediately. The cornea is highly innervated (very sensitive) so you will flinch if something comes close to your eye. I heard somewhere that we have eyebrows to keep stuff from entering the eye but i'm not sure how true this is.

Also, the tears contain biochemicals which have antibacterial properties.

The cornea has an outer layer of cells called epithelia which help keep bacteria out. So if you have some trauma to your eye and there is damage to these cells, there is an open passage for bugs to enter.

Eyelids help by keeping the eye hydrated and they help keep foreign bodies out when you blink.

How can one prevent bacterial infections of the eye...?


while using eye makeup?
----------

Clean all of your brushes, wash your hands often, don't share your makeup with people, if you have an infection, stop using your makeup immediately, and throw away your makeup after about 3 months because my then it has gone bad. Hope that helped! Good luck!  (+ info)

why have I had 3 different eye infections in one year staph, bacterial and yeast infections.Why do I get alot?


My fist guess is that you touch your eyes often. Do you wear contact lenses?

If it is a frequent problem for you, you should start being extra careful any time you rub your eyes or insert/remove contacts. Wash thoroughly with soap and water and you should be ok.  (+ info)

eye infections?


over the past 3 months or so, everyone has had some type of eye infection. I had shingles in my eye for over 2 months. My 14 yr old had pink eye for just a couple of days ( i got rid of it using antiviral drops). My husband got an eye infection a few days ago that left his eye swollen underneath. I washed his eye out and did the same for him as with my daughter and it is going away. Are these eye infections a symptom of some illness? I had a fever about a week ago for a couple of days. I haven't gotten a fever in years. My 5 yr old has had a low grade fever as well on and off for a couple of days.

Has anyone ever had to use, Blephamide Eye Ointment All, for a bacterial eye infection?


My Dr, just gave me a prescription, for this Ointment for a bacterial infection in my eye! Haven't used it yet! If any of you have used it, can you please tell me, #1 Was it painful when you put it in your eye(s)?#2 What were the results when you used it? #3 Did it work and clear up the infection or make it worse? Thanks Everyone!

i had pink eye a couple years ago and was on this. i subsequently gave it to all my friends, so i had to put it in their eyes too. yes, disgusting.

it's tough to put in your own eyes because it's an ointment. have someone else do it for you or it'll end up all over your face. i didn't find that it hurt, just felt a little weird. it worked well... for all of us. :)  (+ info)

Eye infections?


Hey I need help I thank I have an eye infection
when I wake up my eyes are crusted shut

----------

You should really see a doctor,
However in the morning try cleaning with cooled boiled salted water or cooled boiled water with a few drops of bicarbonate soda..... That will clean your eye's and cool them but wont treat the cause if it is an infection....  (+ info)

Are there any medically/scientifically sound "home remedies" for a bacterial eye infection?


I have been prescribed an antibiotic/steroid anti-inflammatory eye drop for my eye infection (red eye, irritated, mucus production). However, I am curious if there are any possible solutions, perhaps say a sterile water/alcohol solution or any OTC type drops you could use to help treat the inflammation or infection. I'm still taking the prescribed drops of course but it would be interesting to know if there was a way (or any theorized ways) to help your eye in an emergency if you could not get to a pharmacy or hospital some time.
----------

Wash your eye in a solution of water and boric acid. It is an old-time remedy that works..  (+ info)
