How to improve from recurrent corneal erosion?

Recurrent corneal erosion is a disorder of the eyes characterized by the failure of the cornea's outermost layer of epithelial cells to attach to the underlying basement membrane.
My symptom is very minor but my eye hurts sometimes when I try to open my eye the first thing when I wake up. Will the condition gets better over time or do I have to live with this.

The cornea has a number of layers. The outermost is the epithelium which sits on its basement membrane. Under this is the stroma which is made of collagen fibers running parallel to each other, going different directions, in multiple layers, then the innermost layer, Decemet's membrane, then the single cell layer the endothelium.

The epithelium is like the skin. It's base layers are sort of square, then they flatten out as they go towards the surface in mutltiple layers.

The epithelium is scrapped off when you blink, little by little, and those cells are replaced by the cells underneath.

When you sleep at night, and get all cozy, into deep sleep, your eye doesn't close completely. It leaves a small space or crack open to the air. This area gets dry. As it gets dry, it can stick to the lid margin. Then, when you go into REM (rapid eye movement) sleep, and you sort of start chasing rabbits in your sleep, you move your eyes and the surface layers tear. OUCH. The eye feels like someone scraped it, or that there's something in there. If you go back to sleep, it'll regenerate the defect and by morning most of the foreign body feeling will be gone.

When this happens more and more, the cells on the bottom will close the defect, but there isn't a basement membrane beneath them as that takes longer to regenerate, so they won't stick tightly. It then becomes easier for the erosion or tearing to happen, thus recurrent erosion.

If you have a mild blepharitis, or lid inflammation, which is usually associated with Staph. bacteria, the secretions of the lid, the fibrin, the cellular reaction and the salts in the tears themselves make the lids a bit more sticky. The lid margine will stick to the drying cornea which is exposed.

To avoid the erosion and allow the basement membrane to replace itself over a month or so, you'll have to put some type of oily, oil-like lubricant between the eye and the lid when you sleep. You could try refresh PM or other ointment such as Bacitracin, Erythromycin ophthalmic ointment or others. I've had this problem in the past and have used just plain old vaseline. It causes the vision to get a bit yellow, but you can wash it out in the morning with water and it won't do any harm to the ocular surface. The ophthalmic ointments require a prescription which shouldn't be that hard to get from your eye doc. They are 'sterile' too. But your eye isn't, so in a pinch the vaseline does work.

Once you've allowed the basement membrane to be replaced, you won't need the ointment. But, if you continue to sleep with your eyes partially open, which you don't really have all that much control over, it'll happen again...hence RECURRENT.  (+ info)

What's better for recurrent corneal erosions: anterior stromal puncture or phototherapeutic keratectomy?

The corneal erosions in this case are non-traumatic, of unknown etiology and conservative treatment (lubricating drops, antibiotics, bandage contact lens) have all failed. Which procedure has a lower recurrence rate, risk of scarring/reduced vision?

Are you experiencing this, or are you researching for project? It would seem a doctor's advice would be in order considering the complications that could occur if someone did not know the whole case history. I hope you get a better answer, I am not sure that I answered you, but I am curious to know.  (+ info)

If you have corneal neovascularization, which is better - gas permeable contact lenses or disposable lenses?

I am not sure which offers my eyes more oxgen - gas permable lenses or the newer, thinner disposable daily contact lenses. An optician at an eyeglass store sold me the disposables, but I am worried that his medical advice was biased by the sale. In the past, I have been told that gas permeables are the best for corneal neovascularization. The optician told me that things have changed with the evolution of the dispoable lenses. Any unbiased help would be much appreciated. Thank you so much!

Some of the daily disposables are great because you get a fresh, clean lens every day so the matrix isn't clogged up by wearing them over time. Ask your doctor for the highest Dk (oxygen permeable) lenses which he/she believes are right for you whether it be soft or rigid.  (+ info)

What is the best vision insurance - my husband needs corneal transplant.?

We are self employed and need vision insurance. My husband has a severe eye condition which can only be treated with a corneal transplant. Of course we can't afford that out of pocket and I'm hoping someone out there can help us with insurance ideas.

Sorry, but no insurance company will accept him with a pending transplant. Also, vision insurance does not cover transplants; those are covered under a health insurance policy.

You might get answers concerning discount cards. Be very wary of these cards. They are not regulated by the Department of Insurance nor do the people that sell them need to be licensed. This means you have little recourse when you have problems with the plan. If you are tempted by the low price and claims of “save up to 80%” be aware that very few doctors actually take these cards. It does you little good if you have to drive 4 hours to find a doctor that will accept the card. Montana couldn’t find any doctors in the whole state that actually took the card and only one dentist who was on probation for unlawful activities so they banned the sale of the card and fined the company. See this link http://www.insurancejournal.com/news/west/2006/11/22/74554.htm for more information. Many other states are starting to ban these cards as well.

Before signing up with any discount plan get a list of doctors. If they won’t give you a list consider it to be a scam. Call the doctors on the list to make sure they’re still taking the card (many don’t even know that they’re listed as a provider) and that they’re accepting new patients.  (+ info)

Why do I have a headache from a corneal abrasion?

I have had a corneal abrasion since Wednesday night. My eye is feeling better, but still not normal. The pain is not as bad, but anytime I try to read I get a bad headache. Is this normal? How long will it last? Could it be from the medication I'm taking to dilate my pupil?

Yup. It alters your vision and thus can give you a headache. Most likely you will have this issue for as long as you are dilating your pupils. Call your doctor and they may tell you to take it easy on your eyes....relax.  (+ info)

What is the treatment for a corneal abscess?

Hello all...
One of my very close friend is suffering from a corneal abscess. i want to know if anyone could brief me about this... thanks

Some people have operations, and recently medical scientists have found that Flucanazole is an effective treatment for those with fungal corneal abscesses (i.e. caused by a fungal infection)  (+ info)

What are some pros and cons of corneal remodeling?

I have myopia [[nearsightedness]] and was wondering, what are some pros and cons were if I were to get corneal remodeling?
Also, are there any risks in getting this??
[[and if there are any people out there that have had this, if I could get your experiance about this and if it helped]]
By the way I'm 18, if this has anything to do with anything. Im not really considering this yet but Im just wondering for the future...


There are at least 16 different forms of corneal remolding techniques which are intended to reshape the front curve of the cornea in a way as to eliminate any error in vision. Each form has it's own set of pros and cons. Since the eyes are usually in a state of change until the early 20's most experts recommend waiting until that time before applying one of these approaches so the results will be more permanent. Which technique is best keeps changing as does the success rate which is in the upper 90's. One of the main risk factors remaining is glare at night.  (+ info)

Is a white spot in the iris area corneal ulcer?

Yesterday as I was taking my contact lenses off, I noticed a white spot in each of my eyes, and some discomfort after I took the contact lenses. Does that indicate corneal ulcer and if it is, do I need to visit a doctor or can I just buy antibiotics and treat myself?

without a proper diagnosis the issue cannot be successfully treated, and you cannot buy antibiotics without a prescription anyway, besides, how would you know which ones to use? Stop being ignorant, see your doctor. Those white dots could be a good deal more serious than just corneal abrasions which will heal on their own if you leave the contacts off for a week.  (+ info)

what contacts should i use after my corneal ulcer?

i got a corneal ulcer 6 months ago in the beggining of september on my left eye due to i was rushing and washd my contacts with water because i didn't have the water solution that day . the doctor says my eye is healed and i can go back to contacts. i used to use acuvue contacts, shuld i keep using these brand contacts or another one? and how much ?

I would think your Dr. should have advised you on that.

Sometimes a daily disposable is better to use after an episode like
you went through.

You will always be more susceptible now to problems like that and more care is needed.

I really think you should ask the Dr. who has seen the severity of the ulcer what he suggests for you to wear now.  (+ info)
