Micropulse Laser Trabeculoplasty as Adjunctive Treatment in Patients With Pseudoexfoliation Glaucoma
April 2, 2018 updated by: Constantinos D. Georgakopoulos, MD, PhD, University Hospital of Patras
Study of the Efficacy of a Single Session Micropulse Laser Trabeculoplasty as an Adjunctive Measure in Decreasing Intraocular Pressure in Patients Suffering From Pseudoexfoliation Glaucoma
This study aims to evaluate the effect of a single session of micropulse laser trabeculoplasty (MLT) on cornea in eyes with primary open glaucoma (POAG) and pseudoexfoliation glaucoma (PEXG).
Study Overview
Status
Completed
Intervention / Treatment
Detailed Description
Patients with PEXG under prostaglandine analogue monotherapy with inadequate IOP control are treated with 360-degrees 532nm MLT.
Patients are evaluated at 1 day, 1 month, 3 months, 6 months and 12 months post-MLT. After trabeculoplasty patients are maintained in treatment with the same drug regimen as pre-MLT.

Experimental: PEXG treated with MLT
Patients with pseudoexfoliation glaucoma (PEXG) under prostaglandine analogue monotherapy with inadequate IOP control treated with 360-degrees 532nm micropulse laser trabeculoplasty (MLT)
|
Micropulse laser trabeculoplasty is performed using the Iridex IQ 532 laser system (Iridex Corporation, 1212 Terra Bella Avenue, Mountain View, CA, USA) and 532 nm (green) wavelength MLT is applied with confluent applications to pigmented trabecular meshwork over 360 degrees using a 300 µm spot size, 300 ms duration, 1000 mW power and 15% duty cycle.
