Abstract

To report on an epithelial inclusion cyst of the iris that was successfully treated with needle aspiration and Ab externo laser photocoagulation. A 6-year-old boy was treated for a 6.0 mm fluid-filled cyst in the anterior chamber of the right eye. Thirteen months previously, he had undergone primary closure of a 6 mm full-thickness corneal laceration. The subsequent cyst was diagnosed as an epithelial inclusion cyst of the iris. His vision decreased to finger-count at 30 cm as the cyst grew over the pupil. We performed needle aspiration of the cyst and Ab externo laser photocoagulation of the cyst wall. The treated lesion was completely removed. The patient's visual acuity recovered to 20/40 without complications. There was no recurrence as determined by slit lamp examination up to 6 months after treatment. Needle aspiration and Ab externo laser photocoagulation can be used to effectively treat epithelial inclusion cysts of the iris.

  Fig. 1 Preoperative anterior segment photograph in an operative microscopic field of an inclusion cyst at POD 13 months after primary corneal closure. This photograph shows a linear corneal scar and a 6.0 mm fluid-filled epithelial inclusion cyst which occluded the pupil. White arrow=margin of epithelial inclusion cyst; Yellow arrow=previous corneal laceration scar.

  Fig. 2 Operative microscopic fields showing needle aspiration of a fluid-filled cyst (A) and Ab externo photocoagulation with an endolaser probe (B).

• 

  Fig. 3 Postoperative anterior segment photograph after needle aspiration and Ab externo laser photocoagulation treatment showing shrinkage of the large cyst.

• 

  Fig. 4 Slit lamp photography showing disappearance of the large cyst in the right anterior chamber 6 months postoperatively. Best-corrected visual acuity was recovered to 20/40 after cyst aspiration and endolaser-mediated collapse of the cyst wall.
