I would suggest you call the retina specialist office and describe your symptoms. Retina surgeons are set up to work people in that have symptoms suggestive of a retinal tear or detachments. The exam the retina ophthalmologist will be much more comprehensive and accurate than the one done by your optom. If you have any family history of retinal detachment or are myopic those are reasons to get in ASAP
I had PVD in my first eye about 11 months after cataract surgery, and in my second eye about 13 months after surgery. The first eye PVD was about a year and a half ago, while the second eye is a few months ago now. I am still experiencing the flashing effect generally where it is dark and when my eyes are closed. And, unfortunately the big floater in each eye has not gone away. The older one perhaps has faded a little but that us about it
There is really not much that can be done without significant risk to deal with PVD. Th big concern is that it is not a retina detachment event and it seems that has been ruled out already. The conservative thing to do would be to see a retina specialist. I have not been referred to one.
