SAN FRANCISCO — The Gold Micro-Shunt not only effectively lowered IOP in a study, but it also showed fewer complications than other drainage devices, according to a glaucoma specialist speaking here.

Robert J. Noecker, MD, and colleagues implanted the Gold Micro-Shunt (Solx) in 76 eyes using a partial-depth scleral incision as part of a prospective study that followed patients for 2 years. Dr. Noecker presented the results at the American Glaucoma Society's annual meeting.

Preoperatively, IOP averaged 27.7 ± 5.9 mm Hg. At 1 year follow-up, IOP averaged 19.7 ± 7.9 mm Hg in 50 eyes, and at 2 years, it averaged 19.7 ± 3.3 mm Hg in 18 eyes, Dr. Noecker said.

The Gold Micro-Shunt is designed to facilitate aqueous flow to reduce IOP without creating a filtration bleb. The device has the advantage of requiring less postoperative management because it is biocompatible and has limited complications, Dr. Noecker said.

"It's a different skill set you have to develop to handle it because it's very fragile," he said. "This procedure, while not perfect, gives us an alternative to other procedures."
