A novel technique for closed-chamber iridodialysis repair

Abstract

Purpose: We introduce a novel technique for closed chamber iridodialysis repair.

Materials and methods: We use a 2.8-mm paracentesis knife to penetrate into the anterior chamber and create interrupted incisions in the sclera. The wounds are 1.5 mm distant from the limbus, at consistent 2.8-mm intervals along the dialysis area. After injecting viscocohesive ophthalmic viscosurgical device through a side port to relieve the synechia and to push the iris toward the incisions, the iris is then grasped by Kelman forceps through the sclera, dragged carefully, and incarcerated. After adjusting the tension of the iris according to the pupil shape, the sclera and the incarcerated iris tissue were sutured together with 10-0 nylon.

Results: The technique was effective in six patients with traumatic iridodialysis.

Conclusion: Our surgical technique repairs the iris, restores the shape of pupil, as well as avoids creating a large incision in the limbus in patients suffering from iridodialysis.
