Spontaneous rupture of secondary iris inclusion cyst causing acute glaucoma and other ocular sequelae

Abstract

A 63-year-old woman with a known secondary iris inclusion cyst in her right eye presented with headache, blurry vision, and eye pain of 3 days’ duration. Initial findings were notable for significant decrease in vision and elevated intraocular pressure in the right eye, with diffuse microcystic corneal edema, diffuse anterior chamber flare with minimal cellular reaction, and a significantly decompressed iris inclusion cyst. On gonioscopy, the right eye was open to scleral spur, and no pigment was visualized. Patient history and presentation were consistent with a diagnosis of spontaneous rupture of iris inclusion cyst causing secondary glaucoma. Iris inclusion cysts are not uncommon; however, ocular outcomes are generally benign and limited to obstruction of the pupillary axis.
