For several years I've had this "cloud" in my right eye and it seems to me that it's slowly gotten worse. It's sort of like a few strands of hair falling down in front of your eye, only I can't brush it away (obviously) and it moves with my eye, staying front and center all the time.
Last Monday (1/9/17) I went to see the VA opthamologist in Bonham. He ran his own private practice for over 30 years. He closed up shop and went to work for the VA because he was tired of fighting the insurance companies.
He told me I had the worst case of asteroid hyalosis he had ever seen. I suppose that does mean I have rocks in my head.
Well, in my right eye at least. 
For most people, asteroid hyalosis doesn't amount to any more than having a few "floaters" - little dark spots that move around in their vision. I have a few of those in my left eye, but in my right eye, they have formed stringy chains that stay in one place. They are all little calcified deposits that have formed in the vitreous, which is the "jelly" that fills the eye.
The only way to remove the deposits is to remove the vitreous, so it's called a "vitrectomy". They make 3 tiny incisions in the white of the eye. One incision is to insert a light so the surgeon can see what he's doing. The second is to insert a little tool that will vacuum out the vitreous. The third is to introduce a saline solution to replace the vitreous as it's being removed.
Needless to say, I'm not looking forward to having this done at all. I am looking forward to getting it over with so I can start healing and get my full eyesight back.
Since the VA is backed up, they're putting me through the Choice program which means it will be done elsewhere. I'm hoping for UT Southwestern in Dallas.
Since my right eye is my dominant eye, this does tie into shooting.
