Doctors find worm swimming in man's eye

CEDAR RAPIDS, Iowa John Matthews is an avid hunter and travels all over the globe. After returning from a recent trip, Matthews noticed his vision was blurry so he went to a doctor.

The doctor ran a bunch of tests before discovering a microscopic worm swimming around in the retina.

"I saw something wiggling and I asked if the worm was wiggling. The doc said, 'Yes.' I said, 'I can see it,'" Matthews said.

"The thing was just thrashing around violently," said Dr. James Folk of the University of Iowa Hospital.

Folk used a laser to remove it. There are only about 15 known cases like this in the world.

Folk suspects that Matthews ingested the worm while overseas, and the worm ate its way through his tissue all the way to his eye.
