Interesting. I told the specialist what I'd seen, they said "not blood cells" but I'm open to re-consideration. I got a pretty complete ocular examination both times, the iris dilation and "I must be a vampire I cannot handle sunlight" is a joy.
I suppose the crap left over from a PVD incident would be a sub-class of "floater" but in quality, its nothing like the floaters I get "all the time" as normal life, before and after PVD.
The one upside of PVD is I am told your chances of a retinal tear are reduced, if you have a "clean" PVD.
