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

Figure 5

Clinical and diagnostic images from case 2. (a and b) Slit-lamp photographs illustrating multiple serous cysts emanating from the inferior iris, obscuring the pupillary opening, and apposing the corneal endothelium. Blood vessels and iris pigment can be seen along the cyst walls. The inferior cysts appear more opaque and homogenous as compared with the superior cysts. (c) AS-OCT showing 4 distinct cavities with low central reflectivity and highly reflective walls, confirming the fluid-filled nature of the iris cysts. The cysts can be seen abutting the corneal endothelium and normal iris architecture is disrupted. (d) B-scan ultrasound image confirming extension of the iris cysts into the vitreous cavity. (e) Slit-lamp photograph showing recurrence of multiple, serous iris cysts that once again appose the corneal endothelium and encroach upon the pupillary opening. (f) Slit-lamp photograph 1 year after cyst aspiration and second injection of 5-FU. There is complete regression of the cysts with residual iridocorneal adhesions.
