I am a 65 yo man who has bad allergy problems. Lately I have been rubbing my eyes a lot. Tonight I noticed flashing lights in the peripheral vision of my left eye. Otherwise the vision seems fine. I have been told to address this ASAP. would Monday be soon enough?

Dr. Rick :

Hi. I'm Dr. Rick and I have two decades of ophthalmology experience. I'm online and happy to answer your question today.

Dr. Rick :

how long did the flashing lights last?

Dr. Rick :

Did you have any other symptoms?

Dr. Rick :

I am a vitreoretinal surgeon :)

Customer: They last less than a second. But they return 5-10 seconds later. No. My vision seems ok in the eye (left), no blur or darkness.
Dr. Rick :

Ok. Thanks for that information.

Dr. Rick :

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.

Dr. Rick :

So. What is the take home message? As long as you do not have any symptoms of a detaching retina that I discussed above, you will be fine waiting to be seen until Monday.

Dr. Rick :

There is no need to consult a retina specialist at this point (we tend to be hard to get into), seeing a general ophthalmologist (eye MD) will be fine

Dr. Rick :

Does this make sense to you?

Customer: Yes, but the flashes are like lightning.
Dr. Rick :

Yes. That is correct....and normal for this condition.

Dr. Rick :

The flashes are only a sign that your retina is being stimulated by the vitreous strands. It is not a sign of a detaching retina or anything terrible at this point.

Customer: OK, so I should try to get in to see an ophthalmologist first thing Monday? Anything I should be doing or not doing over the weekend?
Dr. Rick :

I would cancel your Golden Gloves matches for this weekend but, other than that, you can do normal activities :)

Customer: I like a vitreoretinal surgeon with a sense of humor. Thanks.
Dr. Rick :

My pleasure. I've been at this for over two decades (not JA, retina) and if you don't have a sense of humor the days get kinda long ;)

Dr. Rick :

Take care and have a good weekend. No need to panic at this point.

Customer: Bye
