The Diagnostic and Therapeutic Challenges of Posttraumatic Iris Implantation Cysts: Illustrative Case Presentations and a Review of the Literature

Figure 2

Clinical and diagnostic images from case 1: subsequent presentation. (a) Slit-lamp photograph illustrating recurrence of the iris cyst along the inferotemporal iris after the patient was lost to follow-up for 1.5 years. Posterior synechiae have developed and the pupil is largely obstructed by the iris cyst. A white cataract can be seen through the small pupillary opening. (b) Ultrasound biomicroscopic images demonstrating copious echogenic material within the iris cyst. Normal iris and angle structure are disrupted and the cyst abuts the ciliary body. (c) Slit-lamp photograph showing shrinkage of the iris cyst after repeat debulking of the cyst and intracystic injection of 5-FU. (d) Slit-lamp photograph four weeks after surgical excision of the cyst demonstrating a large sector iridectomy. The cataract was removed with a vitrector and the patient is aphakic. The temporal cornea demonstrates posterior opacity and vascularization in the area previously abutted by the cyst. (e) AS-OCT image four weeks after surgical excision of the cyst. The sector iridectomy is seen. There is increased reflectivity and thickening on the posterior cornea in the area previously adjacent to the cyst where neovascularization and scarring were identified by slit-lamp biomicroscopy (arrow).
