Innovative STING technique shows promise in glaucoma drainage device insertion

A novel surgical technique called the Sulcus Tube Internal Needle Guidewire (STING) shows promise in glaucoma drainage device insertion into the ciliary sulcus, according to a study.

The STING technique aims to address challenges associated with corneal endothelial risks in traditional glaucoma surgeries, offering a potentially safer and more effective alternative for glaucoma patients.

In this retrospective study, researchers examined the charts of consecutive patients who underwent the STING technique using various glaucoma drainage devices, including the Ahmed ClearPath, Ahmed Glaucoma Valve, and Baerveldt glaucoma implant.

Out of 9 eyes studied, 7 demonstrated qualified success, achieving a success rate of 77.8%. The preoperative mean intraocular pressure (IOP) was 23.8 ± 6.3 mmHg, with a significant postoperative reduction to 14.9 ± 3.7 mmHg (P = 0.008). In addition, the average number of preoperative medications per patient was 4.4 ± 0.7, while the postoperative medication count significantly decreased to 3.6 ± 1.0 (P = 0.039).

The STING technique addresses the challenges associated with corneal endothelial risks in anterior chamber tube placement. By utilizing an internal needle guidewire for sulcus tube insertion, the method aims to enhance surgical ease and increase the anatomical precision of tube placement. The results suggest that the STING technique is a promising approach to lower IOP with minimal complications.
