An Australian woman started to lose her vision because of a tattoo she got a few years ago. A rare inflammatory condition associated with tattoos is emerging more frequently across the country.
First noticed the fog in one eye, then the other. The doctors thought it was conjunctivitis. But the tests said otherwise.
“I could barely see,” he says. Nelize Pretorius to . “I was losing my vision and no one could tell me why.”
The source of the problem was not in the eyes. It was a tattoo on the backmade years before.
In a recent study, Australian researchers documented 40 cases of a condition called “tattoo-associated uveitis“, an inflammatory disease that can endanger vision. This complication, once considered extremely rare, may be appearing with more often than doctors thought.
A uveitis occurs when the immune system inflames the uvea, the middle layer of the eye. Symptoms may include blurred vision, pain, redness and sensitivity to light. Without treatment, inflammation can develop into glaucoma or permanent loss of vision.
Tattoo-associated uveitis appears to have origin far from the eye. Scientists suspect that an immune reaction to tattoo pigments may inadvertently reach eye tissue, although the mechanism is not yet clear.
The ophthalmologist Josephine Richards described the mystery directly: “We don’t know why the eye gets caught in the crossfire“, he stated. “There is something in the immune reaction that targets the eye.”
(Increasingly) rare condition
Pretorius’ case is not unique. Across Australia, specialists began to receive patients with similar clinical conditions, often young and tattooed, with unexplained eye inflammation.
“I only became aware of this four or five years ago, and from the moment I found out, suddenly there were all these patients“, diz Richards.
O pattern has become difficult to ignore after several ophthalmologists shared their observations at a conference, says .
The new one, recently published in the magazine Clinical & Experimental Ophthalmologyconfirmed dozens of cases across the countrypotentially doubling the number described in scientific literature since 2010.
The majority of patients required prolonged treatment with immunosuppressants. Only three patients maintained normal vision throughout treatment, while others presented different degrees of visual deficit.
Some were unable to gradually reduce medicationan outcome that worries clinicians, accustomed to seeing autoimmune ocular diseases stabilize over time.
“What really concerns us is we are unable to withdraw the medication to these patients,” says Richards. “Typically, in an immune disease, we treat for two years and then taper off the treatment, hoping that the person will do well without it. But in most cases we are not able to make this reduction.”
Themselves inks used in tattoos are the main suspects. The pigment black was the one that appeared most frequently in affected patients, although red and pink dyes have appeared in isolated cases.
Symptoms typically manifested between one to two years after getting the tattoo, but in one notable case, more than three decades later. Furthermore, as many tattoos were done abroad, it is difficult to trace the exact chemical composition of dyes used.
Despite the alarming cases recently documented, experts emphasize that the overall risk continues to be reduced.
A genetic susceptibility It can influence how each person’s immune system reacts to tattoo pigments. THE microbiome may also condition this response, although the evidence is still preliminary.
For patients, the consequences are immediate and very concrete. Pretorius has already spent thousands of dollars on treatment and continues to rely on corticosteroid eye drops. “We get a tattoo and think the risk is that we’ll regret it later. The real risk is that we could potentially lose our vision,” he says.
Pretorius considers herself lucky. “There are some people with tattoo-associated uveitis who lost their vision permanentlytherefore, in relative terms, I did quite well“, he stated.
As tattoos become increasingly common, study identifies a rare pathway by which immune responses to skin pigments can endanger vision. THE early detection and further study of the mechanisms involved remain essential to prevent avoidable harm.
