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

Figure 3

Steps of surgical procedure from case 1. (a) Intraoperative view of the iris implantation cyst along the inferotemporal iris. (b) A conjunctival peritomy and 180-degree scleral tunnel were fashioned along the temporal aspect of the cyst to facilitate access to and removal of the cyst. (c) The cyst was dissected from the posterior cornea using viscoelasticity. The cornea was then retracted to expose the cyst. Intraocular diathermy was applied along the iris adjacent to the cyst to reduce bleeding prior to performing a large sector iridocyclectomy. (d) The scleral incision was closed with nine 9–0 nylon sutures. After lysis of posterior synechiae, three iris hooks were used to retract the remaining iris tissue and the cataract was removed with an anterior vitrector. (e) Intraocular lens placement was deferred at the time of surgery until longer-term ocular stability could be demonstrated. The patient was left aphakic.
