EyeTechCare – Refractory Open Angle Glaucoma

Access Program Information

Monocentric prospective study conducted in two phases evaluating the secretion and
elimination of aqueous humor by fluorophotometry in patients with glaucoma treated with
cyclo-coagulation with ultrasound.

Population selected:

– Patients with refractory open angle glaucoma despite previous treatments currently
validated for glaucoma.

The purpose of our study is:

– To evaluate the mechanism of action of glaucoma treatment by cyclo-coagulation with high
intensity focused ultrasound in studying the secretion and elimination of aqueous humor by


– First phase: 2 patients (feasibility study) If reduction of at least 10% of the flow of
aqueous humor production at one month in the first two patients in the feasibility
study, further in second phase.

– Second phase: 6 patients
