One in three Americans has a tattoo. In West Hollywood, I can all but guarantee you that number is higher. I got my first tattoo when I was 27. These days it seems just about everyone has one, and I mean everyone. Even granny’s got one!
But all is not well in tattooland. Now doctors are tracking a rare eye condition and are saying it matters more than they first thought.
The condition is called tattoo-associated uveitis. It’s inflammation inside the eye. The strange thing about it is that it doesn’t start there. It starts with your tattoo ink. Researchers think the immune system identifies tattoo pigment as a threat. It attacks like when you’re sick or the body recognizes something foreign and rejects it. Somewhere in that response, the eye gets pulled in. Scary part is nobody has figured out why.
What it does to you
The early symptoms you want to look for are red eyes, pain, blurred vision, sensitivity to light. Some might have those symptoms and blow it off or chalk it up to something else. Nope. Don’t do it. Catch it early and there’s a path through. Don’t, and the damage can become permanent.
A 2025 Australian study tracked 40 patients seen at uveitis clinics across the country between January 2023 and January 2025. Three of those patients had no vision loss during treatment. Thirty had temporary vision loss. Seven had permanent damage, including cataracts, glaucoma, and cystoid macular edema, which is fluid buildup at the center of the retina.
Two-thirds of patients in the study required systemic drugs, meaning pills or injections, not just eyedrops. Nearly half needed biologic medications. Some had to stay on immunosuppression for years. Those are the kinds of drugs transplant patients have to take.
“Usually with an immune disease, we treat for two years and then slowly wind back treatment and hope that the person’s going to be OK off the treatment,” said Dr. Josephine Richards. “But mostly we’re not managing to wind back the treatment.”
The ink matters
Black ink showed up in 25 of the 27 cases where color was documented. A 2026 review of related research found larger tattoos and black ink were more likely to be associated with the condition. Red and pink inks came up in isolated cases as well.
The tattoo doesn’t have to be near the face. One patient profiled in ABC News coverage had a tattoo on her back, inked years before her vision started to go. Chef Nelize Pretorius said she couldn’t figure out what was happening.
“I could hardly see,” Pretorius said. “I was losing my vision and nobody was able to tell me why.”
Her ophthalmologist couldn’t explain the mechanism either.
“We do not know why the eye gets caught in the crossfire,” Richards said.
Certain people face higher risk
Turns out folks with immune systems that don’t regulate well seem to be more vulnerable. Multiple sclerosis, rheumatoid arthritis, inflammatory bowel disease (IBS) — those patients keep showing up in the studies.
Sarcoidosis is another one. It’s an inflammatory condition that mostly hits the lungs and skin, and researchers have noted that an inflamed tattoo can look nearly identical to a sarcoidosis lesion under biopsy. The connection runs both ways and neither direction is settled — nobody knows if the tattoo is a trigger or if the underlying condition just makes someone more susceptible.
The window for symptoms is all over the place. Some patients developed eye problems within three months of getting tattooed. One documented case didn’t surface until more than three decades had passed.
The numbers behind the concern
Pew Research Center found in 2023 that 32 percent of American adults have at least one tattoo, and another 22 percent have more than one. Do the math and you’re looking at something like 84 million people walking around with ink under their skin.
The numbers skew younger and they skew female. Women 18 to 29 are at 56 percent. People under 50 generally land around 46. About half of lesbian, gay, and bisexual Americans have at least one, according to Pew.
West Hollywood is not the national average and everyone who lives here knows it. Tattooing moves through this community — the LGBTQ+ scene, the arts world, not to mention the entire LA scene where just about everyone between 18-65 are inked. The real number here is almost certainly well above what Pew is measuring.
The Australian researchers didn’t bury the condition as a statistical footnote. They said it’s a public eye health issue of concern.
What to watch for
If a tattoo, old or new, becomes raised, inflamed, or changes texture, a dermatologist visit is warranted. If eye symptoms follow, including redness, pain, light sensitivity, or any vision change, that’s an ophthalmologist appointment the same week.
Pretorius said she considers herself fortunate given what others went through.
“There’s a few people that lost their vision permanently,” she said. “So relatively speaking I came off pretty good.”
Other health concerns worth knowing
Now that I’ve got your attention, there are few other health related issues worth noting. Tattoo ink allergies are more common than most people realize. Red ink is the most frequent trigger, but reactions have been documented across every color. Symptoms range from mild itching and raised skin to chronic inflammation that never fully resolves. Some people develop reactions years after the tattoo was done, long after they assumed they were in the clear.
This one has me saying ruh-ro. There’s also the question of where the ink goes. Studies have found tattoo pigment particles in lymph nodes far from the tattoo site. The ink doesn’t just stay where it’s put. Researchers are still working out what that means for long-term health, but it’s not nothing.
One more thing most people don’t know going in. Some tattoo inks contain metallic compounds that can interact with MRI machines. Usually it’s minor — a burning or pulling sensation at the tattoo site during a scan. But radiologists want to know about tattoos before imaging, especially large ones. Worth mentioning next time you’re filling out that intake form.
Very interesting.
