Sneezing cause a Detached Retina?

Question

Since last weekend, I have been having an issue with my left eye (one that previously had retinal surgery years ago). When I move my eyeball left or right, up or down, it seems like a gnat floats by quickly. It is sort of a light flash--but faint, but not like the symptoms that I have been reading about on-line. Could this be a sign of detachment? Is it possible that my excessive sneezing due to severe allergies (the pressure of the sneeze) jarred my retina?

Answer 1

It is caused by pressure, so this could be caused by sneezing.
