The aim of this study was to report a novel presentation of Cogan-Reese syndrome presenting with zonular dehiscence during cataract extraction with intraocular lens placement. A 49-year-old woman presented with worsening vision over 2 years. The examination was significant for bilateral pupil miosis, visually significant cataracts, and unilateral glaucoma. No iris nodules or corneal endothelial disease was observed through slit-lamp examination and specular microscopy bilaterally. Cataract extraction on the left eye was complicated by significant zonular dehiscence. An iris sample taken during the procedure demonstrated histopathologic findings consistent with an iris nodule composed of melanocytic nevoid cells. Cogan-Reese, or iris nevus syndrome, is a subset of iridocorneal endothelial syndrome that usually presents with iridic stromal matting and stromal loss, nodule formation, and secondary unilateral angle-closure glaucoma. Here, we describe a presentation of Cogan-Reese syndrome that presented with pupillary miosis and glaucoma preoperatively, and zonular dehiscence during cataract extraction with no underlying corneal pathology.
