I've seen parasites being pulled out of peoples feet and asses before, but never have I seen a person's eye crawling with worms. That shits like something out of a horror film.
The gruesome footage comes from Karnataka, India, where a 60-year-old dude went to the doctors with a large parasitic worm in the white of his eye. He was seen by Dr Srikanth Shetty who decided the best course of action would be to remove the worm immediately before the guy went blind Here's the video:
If you made it to the end of the video then you're a braver person than me. That's made me feel proper queasy.
