When I had floaters and flashes in my eyes, I learned that I had Posterior Vitreous Detachment (PVD). I'll tell you about the symptoms and what you need to do.

It's a serious condition if the retina detaches from the rear of the eye. But there is no need to panic since it could just be PVD—when the vitreous detaches from the retina. Nevertheless, a quick trip to an ophthalmologist is crucial.

I Suddenly Had a Lot of Floaters

One day I suddenly had arcs of light flashing in my peripheral vision. I didn’t think much of it at the time. I thought it might be a minor migraine attack.

Later in the day, my glasses seemed to be dirty. As much as I tried to clean them, I still saw cloudiness over everything. I thought it was my glasses, but it turned out to be my eyes.

Once I realized my glasses were indeed clean, it became evident that the disturbance was in my right eye. Then I realized that it was a vast number of floaters.

Floaters are like little hair-like strands floating around the eye. I could see them when I lay on the beach looking up at the sky.

We all have a few floaters, and they usually don't bother us. However, this experience became so annoying that I called my ophthalmologist.

He asked me if I had experienced any arcs of light or flashes. “I did, just this morning,” I replied.

He wanted to examine me immediately. He said he didn’t want me to put it off. I had no idea at the time why he was being so insistent about having me rush in right away, but I listened to him and headed right over to his office.

What Does It Mean When You Have Floaters With Flashes?

I learned a lot from that experience. When one experiences these symptoms, it might mean either one of two things:

1. You might have a detached retina.

The detachment causes debris from pieces of tissue to float around the eye resulting in what we call "floaters."

If you have a detached retina, it can be repaired in most cases if taken care of very quickly. However, if you wait too long, you can lose sight in that eye. Don’t wait! Rush to your ophthalmologist as soon as you experience flashes.

2. You might have a detached vitreous.

Another problem that causes the same symptoms with flashes is a detached vitreous. The vitreous is a jelly-like substance filling the eyeball. It’s transparent, and you see right through it.

As we get older, the vitreous tends to dry out and shrink. As it shrinks, it may pull away from the rear of the eye. That is known as a Posterior Vitreous Detachment (PVD).

The retina is on the rear of your eye. It's like a movie screen on which images appear. The retina transfers these images to the brain through the optic nerve. When the vitreous detaches and pulls away, the disturbance sends signals to the brain that simulate arcs of light.

Why the Vitreous Pulls Away From the Retina

As we age, the vitreous in each eyeball shrinks. People with myopia (near-sightedness) have a greater tendency for a shrinking vitreous to pull away and detach because the eyeball is elongated. That is, there is a farther distance from the lens to the retina.

Far-sighted people have a different shape of the eye, being shorter from front to rear. Therefore there's less chance for a shrinking vitreous to detach.

The vitreous connects to the retina only in three places:

  1. All around the border of the retina
  2. At the point where the optic nerve connects
  3. In the macula (the area of the retina where we have the most detail for central vision)

When the vitreous shrinks, it pulls on the retina and can rip part of the retina off the rear of the eyeball. If you have a detached retina and you get it diagnosed in time, you can have it repaired with non-invasive surgery—performed with lasers.

A detached retina is a serious condition. You need to have it repaired quickly!

What Happens After a Vitreous Detachment?

When the vitreous detaches and separates from the rear of the eye, it usually leaves loose cells floating around. You see these as thread-like strands known as floaters.

If it didn't pull and detach the retina, it's not a serious problem. However, since we don’t know if the flashes are due to a detached vitreous or a detached retina, it’s important to get it checked out immediately for a correct diagnosis. That’s why my doctor wanted me to run in to see him immediately.

As it turned out in my case, I just had a detached vitreous. My retina was okay. Nothing needed to be done. My doctor told me that the floaters would disturb me less over time since the brain gets used to them and “learns” to ignore them.

He was right. I can tell I have a lot of floaters if I pay attention to them, but otherwise, they don’t bother me anymore. It took about a year to stop being bothered by them.

Two Years Later: Flashes in My Other Eye

Two years later, I had flashes in my other eye. I suspected it was just the vitreous again. Nevertheless, I rushed to see my doctor since I knew that it could be a more serious problem.

There is no way to tell if it's a detached retina since the symptoms of flashes of light are similar, and there is never really any pain involved. There is no feeling of pulling when it happens, so it's best to get it checked out quickly when flashes suddenly occur.

Lucky for me, my doctor discovered it was only a detached vitreous again in that eye, too, just as before.

IMPORTANT NOTE: Other more severe diseases of the vitreous require more involved repair. Diabetes can cause problems where tiny blood vessels grow into the vitreous. In this case, if the vitreous shrinks and pulls away from the retina, it can detach the retina. The tearing of these tiny blood vessels can cause bleeding into the vitreous. Although this is rare, anyone who has diabetes needs to consider that.

Do the Flashes and Floaters Ever Disappear?

It's been over ten years since I had my detached vitreous. I still see arcs of light and flashes at times. My doctor explained that this comes from the vitreous pulling on the retina since it's not fully detached.

My ophthalmologist said that after the vitreous detaches, there is less of a chance of having a detached retina in the future. Nevertheless, he said it still can happen since it's not fully detached. Therefore, it's necessary to get it checked if I notice any changes.

I always have a routine annual checkup to be sure things are okay. However, my doctor says if I should ever experience more than the usual floaters, I should get it examined quickly. It could mean that the vitreous is pulling the retina off the rear of the eye. That would need immediate attention to reattach the retina.

I never had a problem with a detached retina, glad to say. Also, I've been getting used to the floaters and hardly notice them anymore.

To Conclude

Laser surgery is used for many eye-related refinements, not only to repair the retina. More commonly known, lasers can correct vision (known as Lasik surgery).

Lasers are also used to treat some forms of glaucoma, by a procedure called Laser Iridotomy. I had that done and wrote about it in an article about my glaucoma treatment.

We have superior technology today to help with various diseases of the eye. But you need to be proactive. Take care of your eyes by having regular annual checkups with an ophthalmologist.

      Rosa - You will get used to it as I mentioned in this article. My floaters don’t bother me anymore. Our brain learns to ignore them. Kind of like a filtering process.

      It’s good that your doctor wants to follow up with checking your retina. You definitely always want to be sure that the detached vitreous does not pull the retina off from the rear of your eye. You have a good doctor.

      I started seeing floaters last weekend, called dr and went in the same day to be checked. Will go back a week later to doublecheck retina. Apparently it is PVD but I'm having a really hard time to work most of my day on my computer, I see a lot of them so annoying and crazy to know that these things will be there forever.

      I think it can be quite frightening when something goes wrong with our eyes. I think you did a wonderful job of telling us of your experience and explaining the process. I have a friend that had a detached retina which ended his career as a helicopter pilot. He did seek immediate care but things didn't go well. I'm glad that you have learned to live with your situation very well. Rated up.

      Very good information, my doctor just asked me to get an eye exam just because I haven't had an exam for a couple of years. The warning signs you talked about are good information to have. Rated up.

      Very interesting information. I am glad I read it, as it looks very important to contact your doctor as soon as possible if you have the symptoms, rather than just wait and see what happens. In a way it is scary to know that such things can happen and have such a long term effect in vision.
