She thought it was an eyelash – it was worms
Abby Beckley thought her left eye was irritated because of a stray eyelash. She rubbed her eye, flushed it with water, but when the discomfort remained, she peered into the mirror. She thought she saw a piece of clear fuzz. She pinched it with her fingers and pulled it out.
It was a worm, about half an inch long, translucent and threadlike.
“It was alive and squiggling around,” she recalled.
Beckley remained calm. The 26-year-old was a deckhand on a commercial salmon fishing boat in Alaska. Maybe a common but harmless salmon worm had fallen into her eye. At a local urgent care clinic, the clinicians did not know what to tell her, but they pulled out two more worms. An ophthalmologist pulled out another two.
Beckley became increasingly alarmed. She was not in pain, but her eye was red and inflamed. No one knew how to advise her, and she imagined the worst. Could she lose her vision? Could the worms crawl into her brain? Paralyze her face?
Luckily, her boyfriend’s parents, both doctors, got her an appointment with an infectious disease specialist in Portland, Ore. They also reassured her the worms probably did not have the capacity to reproduce or crawl into her brain.
In the end, it was a team of scientists at the Centers for Disease Control and Prevention that solved Beckley’s case, which happened in August 2016. Scientists at CDC’s special lab that diagnoses parasitic diseases figured out she had been infected by a species of eye worm that had never before been found in a human. By the time her ordeal was over, 14 worms had been pulled from her eye.
Medical parasitologist Richard Bradbury identified the species by searching the medical literature and eventually finding an obscure journal written in German that was published in 1928. The case study about Beckley’s ordeal was published Monday in the American Journal of Tropical Medicine and Hygiene.
“We never expected to see this particular species in a human,” Bradbury said. Until now, this type of worm, Thelazia gulosa, had only been found in cattle.
Eye worms infect a variety of animals, but human infections are rare. The worms are transmitted to eyes by flies. The flies ingest the worm larvae, then land on an animal’s eyes, where the flies feed on tears and other secretions. During this process, the flies deposit the worm larvae into the eye, where they grow into adult worms.
Eye worm infections typically occur in children and the elderly, experts said. Human infections have been reported in parts of Asia as well as in Russia, Italy, and France. The worms cause inflammation but symptoms go away if they are removed. In more serious cases, they can cause scarring of the cornea and even blindness. There have only been 10 other cases of eye worm infections in the United States, but they have not involved the cattle eye worm that infected Beckley.
Beckley’s treating physician, infectious disease specialist Erin Bonura, was in touch with the CDC specialists. They suspected it was an eye worm and recommended Beckley keep flushing them out, pending a final identification.
Parasitic infections often are neglected in the United States, experts said. Beckley’s case, they said, is a reminder that whenever there is the intersection of humans, animals and the environment, “there’s always that chance of things moving across,” Bonura said.
Beckley, now 28, is a sophomore at Southern Oregon University studying psychology. The experience has made her more meticulous about washing her hands.
She hopes her ordeal will help others who might find themselves in a similar situation. Now, at least, there will be articles about her if someone types in “worm in eye,” Beckley said.
“If this does happen to anyone else, I want them to know this girl went through it, and she’s fine,” she said. “And not to freak out.”
