Focused Ultrasound Therapy

Outside Approval Square

Focused ultrasound is an early-stage, noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with glaucoma. This novel technology focuses beams of ultrasound energy precisely and accurately on targets in the eye without damaging surrounding normal tissue. Where the beams converge, the ultrasound produces precise ablation (thermal destruction of tissue) that re-opens the mesh-like supporting channel of the eye were the fluid would normally drain. This enables glaucoma to be treated without surgery.

The primary options for treatment of glaucoma includes medication or surgery.

For certain patients, focused ultrasound could provide a more permanent solution to medications or a noninvasive alternative to surgery with less risk of complications and lower cost.

Clinical Trials Square

Advantages:

  • Focused ultrasound is noninvasive, so it does not carry added concerns like surgical wound healing or infection.
  • Focused ultrasound can reach the desired target without damaging surrounding tissue.
  • It can be repeated, if necessary.

Clinical Trials

There are currently no focused ultrasound clinical trials recruiting patients with glaucoma.
