Primary iris pigment epithelium cysts involve posterior surface of the iris and can occur at pupillary margin or anterior ciliary body. They may be stationary or progressive and sometimes regress spontaneously. These cyst can occasionally lead to angle-closure glaucoma, plateau iris syndrome and secondary pigment dispersion syndrome. A steadily growing cyst may disturb the vision by covering the visual axis and provoke an increase in intraocular pressure (IOP) or even inflammation if it touches the corneal endothelium. There are multiple management options in complicated situations. We report a case of a 17-year-old girl with unusual complaints of hemeralopia and dark-brown discolouration of pupils in both eyes. On examination, she had multiple pigment epithelial iris cysts at the pupillary margins, which were punctured with Nd:Yag laser, and the response was improvement in vision and hemeralopia without any pigment dispersion or IOP changes.
