February 27, 2012 updated by: Luigi Varano, MD, University of Catanzaro

Phase 4 Study to Evaluate Efficacy And Safety of Pneumatic Trabeculoplasty (PNT) in Subjects Affected by Primary Open Angle Glaucoma

The purpose of this study is to evaluate prospectively the PNT safety and efficacy in term of IOP reduction in a group of previously or newly diagnosed glaucomatous subjects.

Study Overview

Detailed Description

A group of subjects affected by Primary Open Angle Glaucoma (POAG) underwent 3 PNT treatments to evaluate one-year efficacy in term of IOP reduction and one-year safety in term of incidence of adverse events

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: PNT treatment
all subjects enrolled in the study, that underwent PNT treatment
A Pneumatic Trabeculoplasty treatment, composed of 3 single PNT applications at day 0, 7 and 90. Each treatment consist in a ocular pneumatic suction of 500inchHg administered for 60 seconds in perilimbal region through the device (model 1000 PNT vacuum controller). This suction is then repeated after a 5 minutes pause.
