Primary Outcome Measures:
  • Intraocular Pressure (IOP) Change [ Time Frame: Baseline to Week 12 ]
    IOP will be measured before and at 6 and 12 weeks after intervention using Goldman tonometry.

Secondary Outcome Measures:
  • Intraocular Inflammation [ Time Frame: Up to week 12 ]
    The count of patients with inflammation defined as anterior chamber cells was measured in each study arm.

Enrollment: 97
Study Start Date: September 2009
Study Completion Date: September 2015
Primary Completion Date: September 2015 (Final data collection date for primary outcome measure)

Detailed Description:
SLT is used to lower intraocular pressure in glaucoma, but it is not know whether the choice of eyedrops administered in the post-operative period affects SLT efficacy. Practitioners commonly use steroid drops, non-steroidal anti-inflammatory drops, or no drops at all. This is a randomized, single-center, prospective, masked clinical trial to determine whether the choice of eyedrop affects efficacy of SLT in glaucoma patients.
