Iris atrophy, posterior synechiae, and persistent photophobia after photo-epilation of the upper eyebrow

Introduction
The aim of report – the complications of the eye after photo-epilation by Vectus Palomar diode laser.

Case report
A 28-year-old woman with BCVA equal to 5/5, who underwent photo-epilation of her left eyebrow. Directly after the hair removal procedure by the Vectus Palomar laser in the area of the left eyebrow, the patient complained of a horizontal oval pupil in the left eye and conjunctival hyperemia in both eyes. We started the anti-inflammatory treatment of steroid eye drops and nonsteroidal anti-inflammatory (NSAID) drops with mydriatics. The observational period was 3 years. Main outcome measures: Visual acuity, intraocular pressure, ophthalmic examination, photos of the anterior chamber and iris.  Twelve hours after the photo-epilation, examination showed uveitis in the anterior section of the left eye, minor tyndallization in the anterior chamber, exudative membrane in the pupil, and posterior synechiae. During 3 years of observation, persistent photophobia, enhanced iris transillumination, and sectional damage to the iris sphincter muscle, iris dilator muscle, and iris nerves were noted. Those resulted in the permanent shape change of the left pupil. Furthermore, the patient observes moving pigment clumps and flashes of light in the left eye. 

Conclusions
Diode laser epilation in the region of the eyelid may result in iris atrophy, posterior synechiae, persistent photophobia, as well as flashes of light and pigment clump movements in the eye. It is essential to pay attention to protect the eye and to be aware of possible eye complications.
