Focused Ultrasound Therapy
Focused ultrasound is a noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with glaucoma. This innovative technology focuses beams of ultrasound energy precisely and accurately on the ciliary body in the eye without damaging surrounding normal tissue.
How it Works
There are a couple of ways in which focused ultrasound is being investigated to address glaucoma.
With the Eye Tech Care device, the focused ultrasound produces precise coagulation of a portion of the ciliary body, which decreases the intraocular pressure by reducing the production of aqueous humor. The result is a non-incisional treatment of glaucoma. The procedure does need to be done in the operating room, as anesthesia is needed.
A second mechanism of action is found in the device made by EyeSonix, which treats open angle glaucoma. The focused ultrasound energy is applied at several locations around the eye, which offer a mild inflammatory trigger to the trabecular meshwork and anterior chamber angle resulting in enhanced drainage of the aqueous humor.
Advantages
The primary options for treatment of glaucoma includes a variety of medications, trabeculoplasty or more extensive surgery that may include implantation of a foreign body into the eye.
For certain patients, focused ultrasound could provide a noninvasive alternative to surgery with less risk of complications – such as surgical wound healing, infection, or implantation of foreign bodies into the eye – at a lower cost. It can reach the desired target without damaging surrounding tissue and is repeatable, if necessary.
Clinical Trials
There are currently no focused ultrasound clinical trials recruiting patients with glaucoma.
The Foundation updates these pages regularly, but with the increasing number of clinical trials, we want to be sure that our audience has the latest information available. Therefore, we also added the website search information for the above trials. If you click here, it will take you to the latest information available from https://www.clinicaltrials.gov/.

Regulatory Approval and Reimbursement
The Eye Tech Care device has regulatory approvals for use in Europe, the Middle East, China, Latin America (Mexico), and multiple locations in South-East Asia (Malaysia, Singapore, Thailand, Philippines, Indonesia, and Vietnam).
