๐๐ฒ๐๐ฐ๐จ๐ซ๐ฆ๐ฌ are a species of ๐ง๐๐ฆ๐๐ญ๐จ๐๐ (roundworm) that like to live in eyes, as you might have guessed. They are found worldwide, which is a horrifying thought for you to enjoy

Any species can get these, including humans!

Most eyeworms are from the genus ๐๐ก๐๐ฅ๐๐ณ๐ข๐, with each animal group having a slightly different species that affects them. These worms can get up to 20mm long, and tend to live in the ๐ฅ๐๐๐ซ๐ข๐ฆ๐๐ฅ ๐๐ฎ๐๐ญ (tear duct) of animals. The worms secrete larvae that are taken up by flies, where they continue development. These flies then deposit the worm onto the eye of the next animal they visit, spreading the infection.

These worms, besides being disgusting, can cause ๐๐จ๐ง๐ฃ๐ฎ๐ง๐๐ญ๐ข๐ฏ๐ข๐ญ๐ข๐ฌ, or inflammation of the tissues around the eye. This can be quite painful and lead to swelling of the eyelids, which makes it hard for the animal to see! In some cases, the worms can also damage the ๐๐จ๐ซ๐ง๐๐ (surface of the eye), which is also immensely painful. Untreated cases with corneal damage can eventually lead to blindness.

These worms are typically diagnosed on an ocular exam, because they can be seen without any special equipment.

The best method of treatment is simply removing the worms. However, if that is difficult to do, our usual antiparasitic medications can also help treat the infection.
