Treatment of peripheral pigment epithelium iris cyst with SLT laser

To report a case of a peripheral pigment epithelium iris cyst treated with selective laser trabeculoplasty laser.

A 15-year-old girl applied to our clinic with the complaint of painless blurred vision in the right eye. Gonioscopy through a widely dilated pupil revealed a clear, oval, pale brown, semitransparent cyst that was located in the inferotemporal aspect of the iris. The cyst was touching the lens, and the lens was pushed superonasally by the cyst. The iris cyst was treated with selective laser trabeculoplasty laser. A small iris notch emerged at the 8-o'clock position of the pupillary margin. Only mild flare and minimal pigment dispersion were documented postoperatively, which resolved in a few days with a topical corticosteroid.

Selective laser trabeculoplasty laser may be considered as a potentially useful and relatively less invasive technique in the treatment of peripheral pigment epithelium iris cysts.
