Help me understand a visual odd happening?

[Rebl2]

7. I have

had these type migraines and I do see zig zag type lines in my central vision. If you see flashing lights in peripheral vision, I would have it checked out. When you get older the gel in your eye may start to shrink and possibly pull on retina which could tear it. Happened to me and my older sister, but we were both right on it and made appointments with our eye doctors. Thankfully it did not tear our retina.
