Worms mate in man's eyes, get plucked out right before larvae burst out

Case study gives a whole new meaning to "bedroom eyes."

After two months of discomfort, a man in South Korea went to an eye clinic where doctors pulled 11 living, wriggling worms from his eyes. They apparently made the most of their time on the man’s peepers; at the time of extraction, many of the female worms were pregnant. The man narrowly avoided having them spew their loads of living larvae directly into his eyes.

The man in this case was a 71-year-old crop farmer. He told doctors that for the previous two months he had the sensation of having something stuck in both his eyes, which were also red and blurry. When ophthalmologists took a look, they quickly saw the problem: multiple mobile, whitish roundworms.

His eyes were not in good shape either, as one might expect. The blood vessels in the membrane over the eye, the conjunctiva, were enlarged, making his eyes look red. And the cells of his cornea—the transparent, dome-shaped outer layer of the eye—had eroded, potentially after the helminths’ hanky-panky.

According to a case report published in the New England Journal of Medicine, the doctors gave the man a topical treatment to numb his eyes and then began plucking out the worms one by one with fine forceps. They collected 11 adult worms, which ranged in size from 11 to 22 mm. Examining the worms under a microscope, the doctors identified them as Thelazia callipaeda nematodes, which are widespread across Asia and have also established in parts of Europe.

These parasites primarily infest the eyes of cats and dogs but can sometimes make their way into human eyes inadvertently.
