The worms more than obliged.

Eventually, her boyfriend called Oregon Health and Science University's infectious disease hotline.

Other worms from the Thelazia family have been reported in humans before but are rare, with just 160 recorded cases in Europe and Asia and 11 in the USA, according to Bradbury. So for 20 days, she pulled live worms out of her eye.

The creatures couldn't be taken out in one go and had to be extracted as they became visible in her eye Richard Bradbury, lead author of the CDC report, told CBS.

"We never expected to see this particular species in a human", Bradbury said.

She found the first worm in her eye in August of 2016, while she was on a fishing trip in Alaska. That larvae then need to hop back on board a face fly to complete its complicated life cycle. They are spread between animals - and sometimes between animals and humans - by flies that feed on the substance that lubricates the eyes. During this process, the flies deposit the worm larvae into the eye, where they grow into adult worms.

P&W working with Airbus, operators on engine problems of A320neo planes
A320neo operators with Pratt & Whitney engines have been plagued by reliability issues since they began flying passengers in 2016. A total of 113 planes in the A320neo family, used by 18 airlines, are now in service that are equipped with the engines.

Two studies have published their findings in The American Journal of Tropical Medicine and Hygiene, with one revealing that a woman in the U.S. state of OR is the first known instance in the world of a human infection with Thelazia gulosa.

"There's only ever been in the history of the published literature 11 cases of [any Thelazia infection] in America, so it's very rare and unusual", Bradbury said. In more serious cases, they can cause scarring of the cornea and even blindness.

Humans have been infected by dog eye worms before. She made medical history because of bad luck. One day, after flushing her inflamed eye with water, the 28-year-old from Grant Pass, Oregon examined it in the mirror and spotted something frizzy. Some doctors were skeptical of her story. "I would say if you think you've been infected with a worm, come to the opthamologist". Then you don't find an eyelash, but you do find a bunch of worms in there. Within 30 minutes, she felt that by-now familiar sensation.

"I was living with these things, and I'd just keep pulling them out when I'd feel them", she said.

Bonura also reassured the young woman this was not likely to be a vision-threatening infection.

"It was shocking when it happened, and it's just fascinating now", she told the Tribune. "She was anxious they would crawl into her brain". When they're ready, they move up to the fly's mouthparts and await eyeball delivery. "Here, we have someone who developed this unusual infection, and the physicians were interested enough to send the materials to the CDC, where they have extraordinary diagnostic abilities".
