Abstract We report the case of a 31-year-old woman who presented with a nine-month history of blurred vision in her left eye. Slit-lamp examination and optical coherence tomography showed four cystic masses hanging at the pupillary margin of the left eye. Neodymium:Yttrium-Aluminum-Garnet (Nd:YAG) laser photocoagulation was used to rupture the wall (cystotomy), drain the cyst content and shrink the remnants of the pigment epithelium, using laser parameters at the lowest effective levels. The patient’s best corrected visual acuity improved significantly after treatment. Despite the increase of pigment at anterior chamber angle, no complication was observed during 6 months of follow up. This is the first report to describe frequency-doubled Nd:YAG laser (532 nm) photocoagulation as a therapeutic option for patients with symptomatic primary IPE cysts at pupillary margin.
