[Indications and results of Sonocare (ultrasound) in the treatment of ocular hypertension. A preliminary study of 395 cases].

Abstract

The Sonocare system CST 100 provides high-intensity focused ultrasound to lower the intraocular pressure by three different mechanisms: partial destruction of the ciliary epithelium, scleral thinning allowing transcleral outflow of aqueous humor, and mainly the ciliary body separation from the sclera. Initially it was used to treat blind eyes with painful elevated intraocular pressure; now the indications are gradually extended to eyes with good vision. This technique takes place between laser trabeculoplasty and filtering surgery. The first 395 cases which were treated with ultrasound these two last years in the Quinze-Vingts Hospital, are displayed in this report.
