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

PURPOSE: To report a new technique to correct tube position in anterior chamber after glaucoma drainage device implantation.

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.

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.

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.
