It may sound like a Hawaiian greeting but trust me, you wouldn’t want to say hi to this one. The Loa Loa is the filarial nematode species that causes Loa Loa filariasis. It is also commonly called the eye worm and it lives inside in the back of your eyeball for up to 17 years. You’ll feel it and it’s contracted with flies which injects the worm directly into your tissue then it travels along your body until it stops and swells at a certain point. It will usually finds its way into the back of your eye and at that point you will be able to see and feel it worming around. Its only treatments are antibiotics or through surgery.
