Timing of Treatment Completion in Staged Selective Laser Trabeculoplasty (SLT): Early vs. Late Completion
- Conditions
- Glaucoma
- Interventions
- Procedure: selective laser trabeculoplasty - early completionProcedure: Selective laser trabeculoplasty - late completion
- Registration Number
- NCT00551395
- Lead Sponsor
- Queen's University
- Brief Summary
This study will evaluate the effect of the timing of treatment completion in two-staged selective laser trabeculoplasty therapy on intraocular pressure lowering effect.
- Detailed Description
SLT therapy is used as an IOP lowering agent in patients with glaucoma. It is unknown whether the timing of a 2-staged approach to the laser therapy will result in better IOP lowering effect.
This study will evaluate the timing (early vs. late completion of SLT therapy) and determined the IOP lowering effect following the interventions.
Arm 1: Early Completion SLT
180 degrees of SLT on Day 1, 180 degrees of SLT on the other 180 degrees on Day 2
Arm 2: Late Completion SLT
180 degrees of SLT on Day 1, 180 degrees of SLT on the other 180 degrees at the 1 month follow up visit.
Primary Outcome: IOP (mmHg).
