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. (

How long until Corneal Neovascularization gets better?
I know after a while, the blood in the vessels goes away and ghost vessels are left behind. What I don't know his how long that takes.
----------
It varies from person to person. It just depends on how rapidly your body heals. Some people heal more rapidly than others. It could last days, it could last weeks. There is no set pace at which the cornea heals.

can i get lasik if i have corneal neovascularization?
at my last eye exam, i was told to stop wearing contacts because they were depriving my eyes of oxygen, and therefore causing blood vessels to form on my eyes. i have really bad astigmatism and do not want to wear glasses. could i be a candidate for lasik or prk?
----------
This will not be a problem at all. In fact, the presence of neovascularization secondary to contact lens wear indicates to me that you should think seriously about having LASIK done. I have had patients with neovascularization have LASIK and even have the microkeratome cut directly through the neovascular vessels. They just bled a little and quickly resolved.
As to your other answerer who told you not to go to an optometrist, I would differ with his opinion. Optometrists are highly qualified to provide pre and post operative care (some are even qualified to perform laser vision correction PRK) and are in a much better position to give you a non biased assessment of your risks and benefits than the opthalmologist who is highly financially vested in the procedure. Patient selection is the number one predictor of success and when a surgeon's selection process is based upon whether you are breathing or not --- well that's just not a real good method of patient selection. Not saying at all that all surgeons are like this. In fact most aren't. But I know personally of one who scares me completely to death!!!!! (

I think i have very mild neovascularization?
So i was looking at my eye closely with a magnifying mirror after i took off my contacts and i saw a little bit of small veins in my eyes around my cornea. Is this normal???
P.S: i think this season i have allergies since my eyes itch sometimes and i just came back from brazil and they were crazy itchy and watery
----------
Dont self diagnose, go to your eye doc where he/she has the tools to fully check your eyes out. Then they can formulate a plan for that (if you have it) and the allergies.
best of luck (

Why are the pathologic conditions peritonitis, pleurisy, and pericarditis all accompanied by pain?
In medical terms anything that ends in '-itis' means swelling. So with swelling comes pain.
Pleurisy is swelling and fluid on the pleura of the lung lining which is a step down from pneumonia.
Hope this helps and have a great day/night.

can the myocardial hypertrophy be recovered if the pathologic stress is reliefed??
Not really, it's called "starlings law" basically it says if you stretch a rubber band and hold it for a long period, it loses it's elasticity. The heart muscle is the same, however, there are medications that can increase contractility and improve cardiac output. (

Neovascularization.....is there a way to aid the reversing process?
Hey!I am a person heavy on 1-day acuvues. Apparently, due to misguidance and I guess carelessness on my part, my doctor diagnosed me with neovascularization. Apart from being myopic,I have never had an other problems. She also said I have astigmatism in both my eyes. However, the neovascularization has me totally stressed out. I know it is reversible. I am drastically going to reduce my contact wear and my doctor suggested the oasys (oxygen permeable)contacts as well. But, my question is...is there just something that we can do to speed the process up?I hate those blood vessels on my cornea and hate all the more that my eyes are unhealthy. Are there some eye drops or any other sort of medication that can be used for getting my eyes back to normal?For treating this neovascularization?To get the cornea back to perfect transparency?Thank you in advance and I really appreciate your responses.

If you take a look at the questions in this forum, you'll see that the majority are about contact lenses. That for itself...indicates something....
When we wear contact lenses, we place a barrier over the surface of the cornea. This barrier when working correctly allows for a fairly good oxygenation of the cornea which is an avascular structure. So it gets it's supply of oxygen from the air, and a little, at the periphery, from the vessels at the limbus...where the white sclera and clear cornea meet.
In order for you to 'make' new vessels, you have to have some condition that doesn't kill the cells being starved for oxygen, .... just makes them sick. And when sick, they complain. The manner of complaining is to make a messenger that tells the blood vessels nearby that we've got to increase the blood supply so we can get enough oxygen. This Vascular Endothelial Growth Factor (VEG-F) also occurs in macular degeneration, retinal vein occlusions, some optic nerve neovascular problems, diabetes, tumors...anything where more oxygen is needed or wanted.
Once those vessels grow, that part of the cornea now has vessels and can now react immunologically... so these people get more infections, have more eye irritation reactions.
By supplying the oxygen, you remove the stimulus and the vessels won't go away, but they'll get smaller and actually become inactive. But the ghost vessel remains...ready if needed.
At this point, it appears you haven't started the multiple corneal ulcer problems. this might be a good time for you to consider one of the refractive surgeries depending on the type of myopia, amount of astigmatism, and/or other ocular conditions.
Treatments that have been tried include laser of those vessels, which works for a short period. And now there are the anti-VEGF medications such as AVASTIN and LUCENTIS as well as STEROIDS that can be used to decrease the inflammatory and the vascular response to the insult (low oxygen). Here you'd be using medications to fix something you can avoid...
Suggestion: stop wearing the contacts for a while. See which of the LASIK or LASEK or Photorefractive Rx, or Cornea IMPLANT, or Intraocular LENS EXCHANGE (cataract surgery without the cataract...just for refractive reasons, which for you would be a medical reason. This seems the 'smartest' way to go) would be good for YOU and get it done. Get it done before you get that really, really
BAD ulcer that causes some serious damage to your corneas. (

Is there a relationship b/w Epstein-Barr and multifocal choroiditis or choroidal neovascularization?
No, there has not been a relationship established (which is not to say it isn't possible though). According to the Center for Disease Control approx 95% of people will have Epstein Barr virus at some point because it is the most common human virus (
