Is It Safe to Fly If You Have Flashes and Floaters?

FloatersFlashesSMALL (1)Have you ever noticed black spots or cobweb shapes floating in and out
of your field of vision? Perhaps you’ve experienced flashes of light
or what looks like lightning in your vision. If these symptoms sound familiar,
you may have
floaters or flashes.

What are floaters and flashes?

Floaters are small pieces of a gel-like substance inside the eye called
vitreous. As we age, the vitreous gel begins to liquefy, and small pieces
may break loose and cause the dark spots or cobwebs known as floaters.
If the pieces of vitreous gel bumps, rubs or pulls on the retina, you
might see a flash of light or even “stars” in your vision.

Most people will experience floaters at some point in time. Nearly half
of adults over age 50 have already experienced floaters in their vision.
Flashes may not be as common as floaters, but many adults will experience
flashes as the vitreous gel shrinks and liquefies with age.

Though they are commonly associated with age, there are some other risk
factors that may cause floaters or flashes. For example, people with nearsightedness,
or who have previously undergone
cataract surgery or YAG laser eye surgery can be at higher risk of experiencing floaters.
Injury and inflammation in the eye can also lead to floaters and flashes.

Are they dangerous?

Both floaters and flashes are generally harmless, but they can be a warning
sign of a more serious vision problem, such as a torn or detaching retina.
If you experience a sudden onset of floaters or flashes, you should contact your
eye doctor immediately for an eye exam. If a retinal tear is diagnosed and treated
early, retinal detachment and permanent vision loss may be prevented.

Is it safe to fly if you have floaters or flashes?

There is no risk associated with flying if you have floaters or flashes.
The only time it may not be safe to fly is if you have had retina surgery
and have a gas or air bubble in your eye following the surgery. Rapid
change in air pressure can affect the gas or air bubble, but it does not
affect floaters or flashes.

Is there treatment for floaters and flashes?

It is not typically necessary to treat floaters. However, you can cause
the floaters to move out of your direct line of vision by moving your
eyes up and down. In the rare case that eye floaters are so dense they
affect vision, or if your doctor determines they are signs of a more serious
problem such as retina detachment, you may need to undergo eye surgery
to prevent permanent vision loss.

Early diagnosis and treatment can result in the prevention of permanent
vision loss due to floaters or flashes. Have a dilated eye exam once a
year or as directed by the eye doctor to ensure your eyes are healthy
but any sudden changes to your vision should alert you to call your doctor
immediately.

  1. This information was extremely helpful. I have a very large consistent floater in my left eye and had a difficult time trying to explain it, but, the term dense sums it up completely. Thanks!

  2. Dear Michelle.

    I read your response and I wish we can communicate because I want to discuss also about floaters with thanks in advance.

  3. Dear Michelle

    My mother experience a detached retina (and further complications which detached again and in the end it left her blind in one eye) some years ago,

    She thinks it was caused by taking a flight a couple weeks before her sudden diagnosis. Can flying cause detached retina? She is now too scared to fly and I fear she’s going to miss out on so many opportunities to travel now because of her fear of further damage, that I believe could be unsubstantiated.

    Could flying cause detached retina?

    Thanks
    Sarah

    I have the same type of floater a dense glob that crosses my line of vision every time my eye moves. Has yours improved?
