What is the treatment for flashes in the eyes?

Hi doctor,

A year ago, I had something struck in the eye, and this caused an eye hemorrhage that lasted about two weeks. Now I still see flashes in my eyes, and when I move suddenly in dark places, and when I close my eye in sunlight and roll it, there is a ball movement across the bottom right of my eye from bottom to side in the far side of the vision which is quite distracting. I saw an eye doctor at the hospital under the slit lamp, and they said there was no detachment or PVD. And had the same exam a few months later. So my question is, do you think this might go away after some time? I did speak to someone online that said this might be fibrous nerve irritation that may someday settle down. Do you think that this may go away after time? Thanks.
