TUG: Therapeutic Ultrasound for Glaucoma

Show Description +

Donald Schwartz, MD, a clinical professor at the University of Southern California Doheny Eye Institute at Keck School of Medicine, demonstrates therapeutic ultrasound for glaucoma (TUG; Eye Sonix). The use of low-power, low-frequency ultrasound, a technique that Dr. Schwartz pioneered, is thought to incite biochemical activity at the angle, thus facilitating aqueous outflow.

Jackson Coleman was using a HIFU (High Intensity Focused Ultrasound) to ablate the ciliary body and decrease inflow. The TUG device has been designed to trigger a mild inflammatory reaction (much like SLT) within the outflow facility. It uses a much lower power and is designed for potential repeated treatments if needed. The intended patient is the large majority of our open angle glaucoma patients as either an initial treatment or as an ancillary treatment. The data reveal a decrease in IOP comparable to first line pharmaceuticals.

Wasn't Jackson Coleman in NY doing a glaucoma treatment with ultrasound for many years? Is this similar and if not how is it a different approach? What has been your clinical experience so far with this method even if it's somewhat anecdotal (i.e. what kind of IOP drops do you see and in what type of patient are you using this?) Thanks.

The hand piece is specially designed and built with a narrow frequency and power range. In addition the ultrasound is focused 1mm anterior to the tip in the anterior chamber angle.

the handpice is a special instrument or like it a dental ultrasound modificated?

It has not yet been published. Only a single site study has been performed, and peer reviewed journals have been negative about such limited studies

has this been published in peer-reviewed literature?
