Iridoschisis

Abstract

Iridoschisis is a rare condition in which a localised area of iris stroma is cleaved in two with the anterior atrophic portion disintegrating into fibrils. The most common presentation of iridoschisis is as an age‐related iris atrophy in association with glaucoma. The association includes angle‐closure glaucoma, angle‐recession glaucoma and open‐angle glaucoma. A finding of iridoschisis is a warning to the clinician to assess the patient for pre‐existing glaucoma and to monitor for glaucomatous changes as it is unclear if iridoschisis is a cause or an effect of raised intraocular pressure (IOP).
