Bilateral acute iris transillumination syndrome. A case report

To present a case report of a patient with a bilateral acute iris transillumination syndrome (BAIT).

BAIT syndrome is a new clinical condition characterised by severe transillumination of the iris, acute onset of pigment dispersion in the anterior chamber, and a medial mydriatic pupil that is unresponsive or poorly responsive to light, due to a sphincter paralysis. Patients with BAIT generally present with acute ocular pain, photophobia, and red eyes.

The case is presented of a 53 year-old woman, who, after being treated with moxifloxacin for an upper respiratory tract infection, developed a BAIT syndrome, which was initially diagnosed as acute anterior uveitis.

As far as is known this is the first case reported in Navarra, but more case reports are needed to establish clear patterns about this condition.
