Iris prolapse at the surgical site: a late complication of nonpenetrating deep sclerectomy.
To investigate the occurrence and management of late-onset iris prolapse through the surgical wound after nonpenetrating deep sclerectomy. Two cases of iris prolapse that presented 8 and 10 months, respectively, after surgery for glaucoma were reviewed. One of the cases was associated with mild trauma. The postoperative follow-up was 5 and 24 months, respectively. The iris tissue bulge did not progress and there were no other complications. The visual acuity was not affected and the intraocular pressure was controlled with medical therapy. These cases demonstrate that the eye is weaker than normal at the surgical site after nonpenetrating deep sclerectomy, allowing iris protrusion. Iris prolapse should be added to the list of late postoperative complications of nonpenetrating deep sclerectomy.
