> _Loa loa_ [so nice they named it twice] is a nematode whose larvae are introduced into humans (such as our patient) who have been bitten by infected chrysops flies in areas of western equatorial Africa. Over a period of 3 to 4 years, the larvae mature into adult worms, which can then live for up to 17 years in a human host, moving at speeds of up to 1 cm per minute as they roam through the patient’s subcutaneous tissues.

The best part of the video is when it finally comes out. There’s also video of botfly larvae extraction on YouTube, which is potentially even more satisfying. I can dig those up if anyone’s interested.

Wow, that’s pretty interesting. So that critter’s been inside her for six years, eh? I can only imagine how relieving it was to finally get that sucker out.

Critters like these are proof that there is a god. And he hates our living guts. Even beer doesn’t make up for eye worms.

I’m curious though, how does one feel something moving in their eye ? Isn’t it just nerveless goop inside ?

The nematode was just barely under the surface of the eye, so even if the majority of the volume lacks nerve tissue (as it likely does, since it’s filled with the vitreous humor) the parasite was in the part most able to feel its wriggly incursions.

On a completely unrelated note, [Isaac Newton did a really _interesting_ experiment on his own eye with a small knife.](http://gravityandlevity.wordpress.com/2009/10/10/the-sins-of-isaac-newton/) The page from his notebooks at the other end of that link has a rather odd illustration.

That is seriously fucken’ gross **Derleth**. You should be ashamed of yourself. Why don’t you just fuck right off and go somewhere under a rock and eat worms or something. ☹

I hate eyeballs. And parasites. Put the two together, and I’ll be over here wretching in the corner. I can handle poop and pus and vomit and blood, but eyeballs make me oogey.

Ah, African eyeworm, or Loaiasis. One of my favorite filarial parasites. Certainly the most dramatic.

I love filarial nematodes. In the classroom, my filariasis lecture is my favorite. Students seem to fall into 2 camps - either fascinated or disgusted.

heh. One of my colleagues got parasitized by a human botfly years ago and didn’t let the doctors remove it - he photodocumented the development instead.

It’d probably be cruel to suggest that the activity of the parasite might feel an awful lot like when you have an eyelid twitching for no apparent reason…

/ducks, runs

Working in Ophthalmology gets you past “body horror” issues about eyes pretty quickly - though I will admit that a coworker getting a papercut on her eye (the white part) did still bother\* me due to the amount of pain that must have been involved.

- I wrote “bug” initially, which seemed way too punny.
