Transcameral suture to prevent tube-corneal touch after glaucoma drainage device implantation: a new surgical technique

<p>PURPOSE: To report a new technique to correct tube position in anterior chamber after glaucoma drainage device implantation.</p><p>PATIENT AND METHODS: A patient who underwent a glaucoma drainage device implantation was noted to have the tube touching the corneal endothelium. A 10/0 polypropylene suture with double-armed 3-inch long straight needle was placed transcamerally from limbus to limbus, in the superior part of the eye, passing the needle in front of the tube.</p><p>RESULTS: The position of the tube in the anterior chamber was corrected with optimal distance from corneal endothelium and iris surface. The position remained satisfactory after 20 months of follow-up.</p><p>CONCLUSIONS: The placement of a transcameral suture offers a safe, quick, and minimal invasive intervention for the correction of the position of a glaucoma drainage device tube in the anterior chamber.</p>
