A Novel Technique for Recurrent Tube Exposure Repair

摘要

Purpose. Tube exposure can lead to vision-threatening consequences and requires prompt surgical attention. Posterior repositioning of the tube to the pars plana has previously been reported as a successful technique. However, this method requires a pars plana vitrectomy (PPV). Here, we describe a novel technique of repositioning the tube into the ciliary sulcus without requiring PPV. Methods. This is a retrospective interventional case report of two patients who had undergone prior glaucoma drainage device implantation and prior tube exposure repair and developed recurrent tube exposure. Tube exposure in the subjects was repaired by repositioning the tube in the ciliary sulcus. Results. The two eyes remained exposure free postoperatively with 51- and 60-month follow-ups. Conclusions. Repositioning the tube to the ciliary sulcus may be an effective technique to avoid reexposure.
