You know, you can’t do it forever,” Bisping said. “Done it for a long time. Of course I’ve got issues with my eye. After the [Kelvin] Gastelum fight then I started having issues with my good eye, which I’ve never spoken about before. … After the Gastelum fight I went to a party with all my team, my friends that had flown in to watch. We went to a club, and because it’s dark I just kept seeing this flash out the corner of my good eye. I’m like, ‘what the hell?’ I kept looking. I kept seeing a flash so I kept looking, and doing that constantly.
“So I started freaking out, going I don’t believe this, I’ve got a detached retina in my good eye. I’ve got problems with my bad eye, it doesn’t look good. So obviously I was kind of freaking out. First thing I did when I got home is I went to a doctor and they checked it out — they say it probably is a detached retina, they looked at it, they say no, it’s not a detached retina it’s a vitreous detachment.”
A vitreous detachment is a term to describe an issue in your eye when tiny fibers break inside the vitreous gel (found behind your retina). According to Bisping, the flashing lights he is seeing stems from those fibers breaking occasionally.
