A species of worm that can infect human eyes has done it again, and this time it chose a 68-year-old woman from the US state of Nebraska.
The woman is thought to be only the second human victim of these worms ever documented.
But the incident signals they could become an emerging parasitic disease in the US.
The woman’s doctors described the disturbing details of the case in a paper published this October in the journal Clinical Infectious Diseases.
Researchers from the US Centers for Disease Control and Prevention also contributed to the paper.
That’s because, a month later, an irritation in her right eye led her to the horrifying discovery of a tiny roundworm.
