Bilateral primary iris pigment epithelial cysts

Abstract

AbstractPurpose To report a patient who presented with bilateral primary iris pigment epithelial cysts.Methods Interventional case report.Results A 30‐year‐old lady with the diagnosis of bilateral primary cysts of the iris pigment epithelium was referred. Her father had been diagnosed with a uveal melanoma 13 years earlier. Two smaller circumferential midzonal iris pigment epithelial cysts and a larger inferonasal cyst located in the temporal area were observed in her right eye, and a similar but much larger cyst was observed in her left eye temporally between 1 o'clock and 6 o'clock meridians. Otherwise, the anterior and posterior segment as well as the intraocular pressure (16 mmHg) were normal. The visual acuity was 20/20 without correction, right eye, and 20/20 with a +0.75 sphere, left eye, with a shadow in the field. For the decrease of vision in her left eye the cyst was treated with neodymium‐doped yttrium aluminum garnet (Nd:YAG) laser cystotomy without any ocular tissue damage using the Abraham iridectomy lens and a 1.0 mJ single pulse. Cystotomy resulted in immediate collapse of the cyst with no change in intraocular pressure.Conclusion Laser cystotomy yielded a favorable result. Generally, these cysts which most frequently occur in young females do not need any treatment, but transpupillary laser cystotomy is an alternative to a conservative regimen if iris the cyst is symptomatic.
