Long term efficacy of repeat selective laser trabeculoplasty.

Purpose: To evaluate long term intraocular pressure (IOP) control after repeat selective laser trabeculoplasty (SLT).

Methods: This single center study retrospectively reviews the electronic medical records of patients with open angle glaucoma undergoing repeat SLT. Eyes with prior argon laser trabeculoplasty, or incisional surgery before or during the study period were excluded.

Repeat selective laser trabeculoplasty can be effective in eyes with initial modest response.

Purpose: To evaluate the effectiveness of repeat selective laser trabeculoplasty (SLT) in eyes exhibiting only a modest response upon initial treatment.

Materials And Methods: Retrospective chart review was conducted of 51 eyes that received initial 360 degree SLT (SLT1) and subsequent SLT (SLT2) from 2003-2011 at a large academic ophthalmology practice. Successful response (S) was a post-treatment 12 month mean IOP reduction ≥ 20% from baseline, while modest response (M) was <20% reduction over the same time.
