Primary Outcome Measures:
  • intraocular pressure (IOP) [ Time Frame: Patients will be followed for one year. Time-points:recruitment, Basal (30 days after recruitment), Follow-Up2 (30 days after basal), Follow-Up3 (3 months after basal), Follow-Up4 (6 months after basal), Follow-Up5 (one year after basal) ]
    to evaluate one-year intraocular pressure (IOP) reduction after a standard pneumatic trabeculoplasty (PNT) treatment


Enrollment: 27
Study Start Date: June 2009
Study Completion Date: January 2012
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: PNT treatment
all subjects enrolled in the study, that underwent PNT treatment
Device: "model 1000 PNT vacuum controller" (the vacuum device for ocular suction)
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.

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
