Rare Tattoo-Related Eye Condition Can Cause Vision Loss, Experts Warn Getting a tattoo can be a thrilling, albeit painful, experience. About one-third of Australians have a tattoo, with many getting inked as a rite of passage. However, a small but increasing number of Australians are being diagnosed with a rare tattoo-related eye condition. It's known as tattoo-associated uveitis and can cause permanent vision loss. So what is this condition? And what do tattoos have to do with eye health? How might a tattoo impact my eyes? Tattoo inks used in Australia and other countries may contain toxic chemical, which have been linked to the development of certain cancers. This is a concern from a regulation perspective. That's because Australia, compared to other jurisdictions, has less strict rules around what ingredients go into tattoo ink. The European Union, for example, bans many of the inks that are allowed in Australia. From a health perspective, the vast majority of people don't react to these chemicals. But in some cases, they may trigger a harmful immune response. This happens when a person's immune system recognizes the ink as being dangerous and starts attacking the tattoo site. This can cause inflammation, both of the tattooed skin and other parts of the body. Inflammatory cells from a tattoo may breach the blood-ocular barrier, which is a wall-like structure designed to protect the inside of the eye. If that happens, inflammation can spread to various parts of the eye. This includes the uvea, the middle layer of the eye, which helps it focus on nearby objects. The uvea also contains the colored part of the eye, the iris. If your uvea becomes inflamed, you may develop the rare condition known as tattoo-associated uveitis. Symptoms include sudden pain, red eyes, and increased sensitivity to light. In severe cases, this condition can lead to glaucoma, which refers to several eye diseases caused by damage to the optic nerve, or scarring on your eye. Both complications can cause blindness, if left untreated or if treatment is delayed.
