Serious eye and contact question?

Question

i went to the optomitrist yesterday. he said that due to lack of oxygen, my cornea is growing blood vessels in it. he says that once the blood vessels cover my cornea, it would do permanent eye damage.
i am now using acuvue advnced because the doctor say that it will give me more oxygen to my eye.
i am also wearing glasses in the morning and at night.

how long will it be until they stop growing, and is this possible to be corrected?
also, do you have any tips?

Answer 1

If you are accurately reporting what the optometrist said, he is a very poor communicator.

Encroaching blood vessels *are* a sign of inadequate oxygen supply to the cornea. Contact lenses with higher O2 transmission may well help.

The blood vessels never grow across the entire cornea, and they are not themselves the threat, though if allowed to become well established they can give a permanent "red-eyed" look.
But inadequate oxygen can lead to loss of corneal endothelial cells which can have implications for later life, including losing the possibly of wearing contact lenses, and in very extreme and rare cases, corneal oedema with pain and very poor vision.

The tips: Do not overwear lenses.
Never sleep in them.
Have adequate back-up spectacles so you are not tempted to use your contacts when your eyes are telling you they need a break.
Use contacts with high oxygen transmission.

This is called corneal neovascularization... it may be superficial or deep, and may be sectorial or may extend 360 degrees into the cornea. This is often a result of chronic hypoxia (lack of oxygen to cornea) from a lens that is too thick, tight or "clogged" up with protein deposits.

Small amounts ( 1-2mm) of peripheral superficial vascularization are relativly common in extended wear.
Greater then 2mm of progressive vascular ingrowth or ingrowth involving the middle or deep stroma is uncommon.
Stromal vascularization is a more serious complication of contact lens wear and can lead to compromised vision.

The management of corneal vascularization depends on the severity. In mild cases you may be refitted with a flatter or thinner lens or can be switched to a gp lens. This allows for the increase of oxygen to your cornea. With severe cases contact lens use will be discontinued...severe cases can end in blindness. Since you are still wearing contacts sometimes, you have a milder case. The growing will recede when your cornea is not deprived of oxygen. Even when it recedes you will be left with ghost vessels. The amount of time for it to recede can vary from person and severity.

The best thing you can do is limit your contact lens wear whenever possible. Take your contacts out earlier then you usually would. Wear your glasses more often. Your eyes need a break hun!
The reason why this is happening is due to lack of oxygen to your cornea. To get more oxygen where your contacts less.... this is pretty serious... you do not want it to get worse because in severe cases it can lead to blindness.
Good luck to you and take care of your eyes :)

Answer 3

The neovascularization is due to oxygen deprivation as mentioned in several posts above. It can impede the visual axis if allowed to proliferate. Your doctor was correct in putting you in lenses with higher oxygen permeability. Once the cornea begins to receive enough oxygen, the blood will begin to recede from the vessels. The vessels will remain and are termed "ghost vessels" but will not continue to grow. Your doctor should be monitoring you to ensure that the condition is not worsening. If so, your contact lens wear may be truncated if not eliminated altogether.

gosh i hate disputing other professionals...BUT:

i have personally witnessed contact lens induced corneal neovascularization impeding the visual axis and vastly reducing best-corrected acuity. the blood vessels themselves are, indeed a "threat", as well as the loss of endothelial cells and limbal stem cells.

Answer 5

Get some cool glasses, 4 or 5 pair and change up for different occasions. Plus they have these ultra thin high power ones now.

Answer 6

These are questions you should direct to your eye docter. I'm legally blind, for whatever reasons, and the carrot theory is NOT true. Eating carrots does not make your sight better, cuz i used to eat carrots all the time and, look at me!

Answer 7

by and large those causes: Zoned out, a sluttt, thinks youre lovely, watching out the window, soo top that she appears like lindsay lohan, under the influence of alcohol, she used to be having a imaginative and prescient... and so on.
