Hi. I'm online and happy to answer your question today.
There are a large number of thing that can cause this.
Where is the fluid? Have you seen an ophthalmologist?
Have you seen a retina specialist?
Can you give me anymore information?
I see that you are typing and that could mean a couple of things: 1. you are actually typing or, 2, the chat system has frozen up. I'll give it a few more minutes and if I've not seen anything from you I'll switch over to the Q&A system. That system works a lot like 'text messaging' but, unlike the chat system, it almost never freezes up. We can continue to work on your question there. :o)
Directly behind the retina. Yes. Yes. It's been over a year since my "Episode" - a kind of "explosion that left my eye covered with a "film of dust particles" and floating golden halos mostly seen in darkness.
