A 38 year-old man presented to the outpatient clinic of our centre with mild pain and redness in the right eye for the past two days. He also complained of gradually progressive decrease in vision in the right eye for the past one year. He had sustained a penetrating injury in the right eye six years ago, and had undergone surgical repair of the wound at another centre. The vision in the right eye was hand movements with accurate projection of rays in all four quadrants. Apart from minimal circumcorneal congestion, there were no signs of ocular inflammation. An irregular scleral scar was noted at the superior limbus at twelve o’ clock position, extending about two millimeters posteriorly, with extension into the cornea just within the limbus. A cyst of the iris was seen in the superonasal quadrant, extending from twelve to two o’ clock position, associated with epithelial downgrowth and extensive peripheral anterior synechiae from ten to two o’ clock position. A total cataract obscured the view to the fundus. The intraocular pressure was normal and there was no relative afferent pupillary defect. The left eye was normal. Ultrasound biomicroscopy of the right eye showed a thin-walled iris cyst with internal echolucency. There was no evidence of a foreign body. B scan ultrasonography of the right eye showed a clear vitreous with no evidence of a foreign body or retinal detachment. The patient underwent surgical excision of the iris cyst with cataract surgery under cover of topical corticosteroids. The cyst wall and peripheral anterior synechiae were separated from the corneal endothelium by gentle viscodissection. Posterior synechiae under the iris cyst were also released by viscodissection, aided by mechanical separation with the cannula used for injection of the viscoelastic agent. After conjunctival peritomy, a limbal incision was made from ten to two o’ clock position. The iris cyst was excised in toto, with excision of a one-millimeter margin of surrounding iris tissue. The epithelial downgrowth was also excised, and an extracapsular cataract extraction was performed with implantation of a rigid, single piece intraocular lens in the capsular bag. The limbal incision was sutured with 10-0 nylon sutures. The excised tissue was sent for histopathological examination, and was reported as a benign epithelial cyst of the iris. The post-operative period was uneventful. There was no significant ocular inflammatory reaction, and fundus was normal on dilated ophthalmoscopic examination. The patient was followed up in our clinic, and the best-corrected visual acuity in the right eye was 20/20 at the last follow-up visit three months after surgery.
