Hi. I'm Dr. Rick and I have two decades of ophthalmology experience. I'm online and happy to answer your question today. Dr. Dan does not seem to be online at this time.
You are likely experiencing a PVD or posterior vitreous detachment, a common event that happens in many people.

You have a thick gel material in the middle of your eyes called the vitreous. Over time as it liquefies, this gel material collapses on itself, forms little clumps that you can see as dots, lines or bugs. As these clumps form the vitreous pulls away from the wall of the eye. In the process it can stimulate the retina -- causing the flashes that you may see.

It is recommended that you see your ophthalmologist to look at the retina to make sure there are no problems such as a retinal hole or tear. In most cases, there are no problems, but this exam is precautionary and allows for preventative treatment of any lesions that are found.

If you notice a sudden increase in floaters, flashes of light (like a lightning storm), or a shadow/veil in the periphery of your vision, this can be worrisome for a retinal detachment. You would need to contact your ophthalmologist promptly in that case.

What can you do about the floaters? Well, floaters don't go away, and they don't really get worse. Over time they tend to "sink" out of your central vision and you brain "filters" them out so you don't notice them so much anymore. They almost never cause significant visual problems except, of course, if they cause a secondary retinal detachment as discussed above. The only way to decrease or remove the floaters is with a major surgery called a vitrectomy. As a retinal specialist for almost 2 decades I've only done this procedure to remove floaters in a handful of cases.

Here is a video of the actual surgery to remove floaters:

In January 2013 a new drug, called Ocriplasmin, was approved by the FDA to dissolve vitreous strands in a particular eye condition called vitreomacular traction. Perhaps someday this drug could be used to also remove floaters…. Only time will tell.

Does this make sense to you?

he checked teh retina and it was ok


 


today I have a rash of floaters round circlus with dark doats in them but then they went away I have not told my doc yet will do so in the am what was that?

I am a retina surgeon.

If you have had a sudden increase in the number of floaters then you should have repeat retina exam done in the morning....even though you just had one.

This increase could be a symptom of a tear/bleeding in the back of your eye.

Make sure you are examined by an ophthalmologist (eye MD) and not an optometrist for this issue.

There is no need to panic right now, but do have a recheck tomorrow AM.

Does this make sense to you?

Robert,

One other thought....

If these round circles are in the periphery of your vision, last for about 15 minutes to an hour and then go away, you may be suffering from a different issue called ocular migraine.

Here is information on that other condition:

A typical migraine headache starts with shimmering lights, often times they surround a blurry area or have dots or jaggedly lines associated with them. They tend to progressively increase in intensity and sometimes march across the visual field causing difficulty with reading. Many times this is then accompanied by nausea, irritability, sensitivity to bright lights and/or loud noises. After the onset of the lights (called scintillating scotomas), the headache typically starts and the light show tends to progressively go away.
Many people can have this migraine phenomenon WITHOUT the headache; it is called an acephalgic migraine. Some people even start having these late in life, or may have had a few much earlier in life that behaved differently and haven't had any for decades and then begin to have them; this is not uncommon. A family history of migraines is often present as well.
This is nothing to worry about. It is not a sign of a more serious underlying condition, brain tumor or anything like that. If the episodes become so frequent that they are bothersome there are medicines that can be used to decrease their frequency or stop an episode once it has started.
I, personally, have been suffering from this condition for almost 30 years. I almost never got the headaches after the visual effects.
There was one time, I was in the middle of a very delicate retina operation, when an attack started. After a few moments I lost most of my central vision and the inferior part of my visual field. I, calmly, removed my surgical instruments from the patients eye and we all sat around in the OR for 15 minutes until my vision returned. Other than that my ocular migraines have not really caused me any significant problems :o)


This problem does not require a retina exam in the morning.....


Don't forget to mash the positive feedback button for me...the one labeled "excellent" is the most fun to push by far ;)
