Weird, fast moving spots....

Hi there.  Within the last month, I've developed weird type of floaters.  Not the dark ones that seem to settle on your eye, and move around when you move your eye (although I do have these as well, but I've had them forever).  No, these look more like little bubbles, and they move without the assistance of me moving my eyes.  Normally each one is only visible for about a half second, but there's a bunch of them, shooting in all different directions.  Most of the time I see them more in my peripheral vision, but sometimes they are right in front, and in these circumstances they are all lit up!  Normally each episode only lasts for about 10 seconds.  I went and had my eyes checked today, and the doctor couldn't find anything abnormal.  She told me that my symptoms are probably not eye related since I seem to be experiencing the spots in both eyes (which is why I've posted this question under neurology).  However, after having the exam, I seem to be noticing the spots a lot more, possibly because she dilated my eyes.  What in the world could be causing this?

(BTW - I'm 8.5 months pregnant, and don't know if it could have something to do with that or not.  My ObGyn doesn't seem to think it does.)

Hi there. Causes of eye floaters are multiple like myopia , diabetic retinopathy, vitreous syneresis, posterior vitreous detachment which is different from retinal detachment.  Both of these can cause eye floaters, red blood cells due to hemorrhage and white blood cells due to inflammation are common types of cellular material causing eye floaters. this hemorrhage in vitreous may be due to injury , retinal tear through a blood vessel, eye surgery. Inflammation in vitreous due to uveitis, infection etc. consult an eye specialist and get your eyes examined till the posterior chamber. If these are ruled out visual hallucinations could be causing these. Hope this helps. Take care.
