Case study of Tattoo-associated uveitis

Case study of Tattoo-associated uveitis

Dr Kisha D. Piggott, at Saint Louis, MO.and colleagues have reported a case of Tattoo-associated uveitis that has appeared in JAMA clinical challenges.

Tattoo-associated uveitis was first described by Lubeck and Epstein in 1952, but to this day this rare ophthalmic complication remains incompletely understood. One of the earliest reports of tattoo-associated uveitis described patients with histologically confirmed tattoo granulomas and concurrent ocular inflammation. Tattoo-associated uveitis occurs 6 months to 10 years after tattoo placement. It has been suggested that the ocular manifestations represent a delayed hypersensitivity reaction to the tattoo ink.

According to history, a 26-year-old white man presented for evaluation of blurry vision over the past year. He had no back or joint pain or skin rashes. Five years ago he had a black ink tattoo placed on his left arm, and 3 years ago a second tattoo was placed on his right arm. Two years after the right arm tattoo was placed, he noticed tattoo elevation on the left arm and onset of decreased vision. He had recurrent episodes of ocular redness and blurred vision, coincident with inflammation of the skin surrounding both tattoos. Two months before presentation, bilateral peripheral iridotomies (iris laser procedures) were performed because of inflammation-induced adhesions between the iris and the lens.

At presentation, best corrected visual acuity was 20/20 in the right eye and 20/40 in the left. Intraocular pressure was 34 mm Hg in the right eye (upper limit of normal, 21 mm Hg) and 11 mm Hg in the left. On anterior segment slit lamp examination, there were no visible inflammatory cells in the anterior chamber of the right eye, but there were more than 26 cells per 1-mm field in the left. The left arm tattoo was elevated, with nodular elevation most prominent at the superior aspect of the tattoo. Punch biopsy of the tattooed skin revealed epithelioid histiocytes with macrophages containing coarse black granular pigment. Results of testing for syphilis, tuberculosis, and sarcoidosis were negative.

The patient was started on topical prednisolone acetate eyedrops for the treatment of ocular inflammation. The patient continued to have episodes of uveitis, even after prescription of adalimumab and methotrexate, requiring administration of short-acting intraocular steroids. His vision worsened progressively over the subsequent 9 months until he had difficulty counting fingers at 0.3 m (1 ft) in each eye. The visual decline was attributed to cataract and persistent inflammation. He underwent bilateral fluocinolone acetonide implantation for improved long-term control, with concomitant cataract surgery 12 months after presentation. One month after surgery, best corrected visual acuity had improved to 20/300 in the right eye and 20/30 in the left, with improved intraocular inflammation.

  • Tattoo-associated uveitis is a rare, late sequela of tattooing that is not completely understood.
  • Onset of uveitis typically occurs 6 months or more after tattooing.
  • Tattoo ink may serve as an antigenic trigger for the development of granulomas in patients susceptible to sarcoidosis.
  • Tattoo-associated uveitis may be associated with systemic sarcoidosis or may represent a delayed hypersensitivity reaction.
  • Management options include local steroids, systemic prednisone, steroid-sparing agents such as methotrexate, azathioprine, or adalimumab, and excision of tattooed skin.
  • Before initiating immunosuppressive therapy, however, common etiologies of uveitis, such as tuberculosis and syphilis, should be ruled out to avoid missing a diagnosis that could be exacerbated by steroid or other immune-compromising therapy.
