What's the difference between corneal abrasion and ulcer?


What's the difference between a corneal abrasion and a corneal ulcer?

also, if I use eye drops and my eye becomes super red, is it because the eye drops have become infected with something?
----------

A corneal abrasion is exactly what it says it is. It occurs when something (a finger nail, a pencil, a stick) mechanically scratches the cornea and removes some of the epithelium that covers the surface. It is not an infection.

A corneal ulcer is an isolated (can be large or small though) area of inflammation related to an infection of the cornea by a pathogen. The most common cause of a corneal ulcer is bacteria, although ulcers can occur associated with other pathogens such a viruses or fungi. These are active infections and should be treated agressively by either antibiotics, antivirals, or antifungals.

As to your last question it depends upon what type eye drop you are talking about. It is possible that you may be allergic to an ingredient in the eye drop. Only way to know for sure what is happening is to go in and let a doc take a look.  (+ info)

What can you tell me about having a corneal transplant and lens implant during the same procedure?


A 26-year-old employee of mine has asked for medical leave while he has a "corneal transplant, a lens implant, and possibly a retinal transplant." I have my doubts about his claims regarding these procedures. From what I have researched, retinal transplants are still in the "experimenting on mice" stages, and corneal transplants do not go hand-in-hand with lens implants. I don't want to deny him the time for a legitimate procedure, but we're a very small, four-person operation, and I can't afford for him to take a "vacation" (as he has on other occasions) by using a medical excuse. Twice before he has taken a day off, supposedly to have this done, only to claim the next day that there was a problem with the donor cornea and the procedure had been postponed. I need some expert info on these procedures, please. Thanks.
----------

The lens and the cornea are occationally replaced at the same time. Retinal transplants are in develpment stages still...

Ask him to get a note from the doctor on an official letter head since you aren't sure about his claims.

Most people are able to get back to work with in 7 days after a corneal transplant, though the actual recovery and healing of the cornea can take upto a year.  (+ info)

How much does it cost to get corneal ring implants in your eyes?


I have mild nearsightedness and was considering this option. Does anyone have any experience with corneal rings?
----------

It will vary quite a lot, however it appears it will be as much or more than LASIK which is averaging about 2000 dollars per eye.

"The cost of Intacs is roughly equal to, or more than, LASIK in most centers."  (+ info)

How can corneal Abrasions lead to blindness?


How severe must a case of corneal abrasions be, when left untreated, for it to lead to blindness?
Which are some situations in which a case this severe is most likely? I have heard that infection following corneal abrasions may lead to blindness, is this true?
----------

Most corneal abrasions heal very rapidly, but there are some times when this normal healing could be complicated by infection -

The example that springs to mind would be ulcerative keratitis, which can lead to blindness. It's caused by a normally harmless bacteria called pseudomonas aeruginosa, but if it gets into the cornea and is allowed to sit there (think, putting a contact lens over it), then it can lead to a very rapid (24-48 hours) infection and then blindness.

That's why individuals with corneal abrasions are prohibited from wearing contacts. That would be the only immediate cause - as they do heal quite quickly. Hope this helps!  (+ info)

How can i tell if i have corneal abrasion or an eye infection?


i took my contacts out and one eye is really red and sensitive to light and gets really teary. how can i tell if it's a corneal abrasion or an eye infection and how do i fix it?
----------

From what you are describing it sounds like a corneal abrasion. It is quite possible when you were wearing your contacts a foreign particle could have got trapped under the lens and scratched up the cornea. The symptoms you are describing would be a good indication to go to a doctor/eye doctor asap. http://www.emedicinehealth.com/corneal_abrasion/page4_em.htm

If it was an eye infection you would see discharge of some sort in your eye. Anyways to be safe go see an optometrist or ophthalmologist to check your eyes out, to diagnose and treat the problem.  (+ info)

Does anyone use the contact lenses that do corneal molding or orthokeratology?


I looking for others' experiences with the contact lenses that correct your vision overnight by corneal molding. What were your experiences, how long did it take to work, were they uncomfortable, how much did it cost you? Thanks in advance!

How can my friend get some help getting a corneal transplant- financially mostly?


My friend, who is 40, and lives near Houston, Tx. has been out of work for over 4 years mainly due to the fact he became legally blind. He had one eye operated on already (corneal transplant), and his vision in that one eye has improved. However, he is still legally blind in the other eye. Soon, my friend may be able to drive and work again, but that hasn't happened yet.

My friend is eager to have his sight in both eyes, rather than just one. The organization that helped him with the first surgery won't operate on the second eye. So now my friend doesn't have the funding to pay for the entire procedure.

Any useful advise (orgainzations, clinics, websites, etc.) for my friend in how to get assicstance for his much needed eye operation. Thank you.
----------

Tell hhim good luck. Most people can't get that surgery till they qualify for Medicare, no matter how long they've needed it. Our society has really developed a Catch-22 vicious cycle when it comes to damage that virtually prevents employment. You lose the job, can't afford the COBRA insurance, already made too much that year to get medicare/medicaid, can't work till after successful surgery, can't remortgage the house to pay for it but will lose everything if you can't find a job.
I hope someone has your answer!  (+ info)

Corneal Abrasion :A sensation of a foreign body in the eye (for example, a feeling that there is something in your eye that you cannot get out). This feeling sometimes develops a few hours later rather than immediately after the apparent injury.
-Tearing of the eyes
-Blurred vision or distortion of vision
-Eye pain when exposed to a bright light
-Spasm of the muscles surrounding your eye causing you to squint
You may have got a foreign particle under your contact lens that scratched your cornea.

As for eye infections there are many types but you if you have one you will probably have some sort of goopy discharge coming out of your eye. Here are some other possible symptoms
-Red eyes.
-In bacterial conjunctivitis: pus discharge from the eye or a morning crust on the eyelashes.
-In viral conjunctivitis: watery discharge from one eye only, sometimes with crust, sore throat, or runny nose.
-In allergic conjunctivitis: itchy, burning, and watery eyes, swelling around the eyes, runny nose and sneezing, or a sensation of having something in the eye.

You need to see a doctor or eye doctor to diagnose it because if you don't know whats wrong you can't really do anything to fix it.
If it is a corneal abrasion this link will bring you to at home treatments http://www.emedicinehealth.com/corneal_abrasion/page7_em.htm

The best thing you can do right now is not too touch it because if it is infected you could infect other people or your other eye.  (+ info)

Where can I get a corneal transplant done without insurance or cash?


I've had Ice Syndrome for 4 years , Iam in intense pain, my corneal is in bad shape , feels like broken glass in my eye
----------

Check with an opthalmologist to see if they have any plans where you can take out a loan with them and pay in payments. They do this sometimes with lasik surgery. Hospitals have to offer some care to uninsured patients for free, you could check with the hospital. Or you could try to get a second mortgage or a loan on your car or a signature loan without collateral at the bank.

Here are a couple of links for eye care help...not sure if they help for your surgery or not, you have to check with them..

Need eyeglasses or eye care?
