[Ocular complications in intense pulsed light therapy (case study)].

A 24-year-old female patient with photophobia, discoria, redness and dryness in her right eye after intense pulsed light (IPL) therapy applied for posttraumatic subcutaneous hemorrhage received a comprehensive ophthalmic examination including optical coherence tomography (OCT) and OCT angiography of the anterior eye segment. Her best corrected visual acuity was 20/20 in both eyes. Medically induced mydriasis revealed discoria with paresis of pupil dilatator in the left eye (pupil size 4.2 mm and 6.6 mm in the right and left eye, respectively). Anterior segment OCT showed anterior chamber cytosis and increased iris vascularity. The patient was prescribed topical 1.0% tropicamide 2 times per day and 1.0% dexamethasone 4 times per day for two weeks. Examination performed after 3 months showed no restoration of pupil dilatator function in the left eye. The case demonstrates potential ocular complications of IPL therapy, which may include iris burn with iritis and persistent pupil dilatator dysfunction.
