Abstract

Purpose: : To evaluate the efficacy of repeat selective laser trabeculoplasty (SLT) in patients with open-angle glaucoma.

Methods: : Charts of patients that underwent SLT by 5 physicians at the Glaucoma Center of San Francisco were reviewed. Demographic information, visual acuity, intraocular pressure (IOP), extent of treatment and type of prior laser treatment were recorded. Patients with less than 2 months of follow up were excluded. Main outcome measures were IOP and need for further IOP lowering procedure. Success was defined as achieving target IOP.

Results: : 44 eyes of 38 patients were included. The patients were predominantly Caucasian (70.4 %) and the majority had primary open angle glaucoma (86.3%). 35 (79.5%) eyes underwent 360° SLT and 9 (20.5%) had 180° SLT. 27(61%) eyes had prior 360° SLT, 16(36.3%) eyes had prior 180° SLT, and one eye had prior 90º SLT. 13 (29.4%) eyes also had a history of treatment with Argon Laser Trabeculoplasty. Average follow-up was 34.5 weeks (range 3 weeks to 2.3 years). Average IOP at last follow up had decreased by 2mm Hg and the change was not statistically significant (P value = 0.02). 19 eyes (43.2%) patients achieved target IOP at last follow up; of these, 12 eyes (27% of total eyes) had more than 20% reduction in IOP from baseline. 25 eyes (56.8%) were not at target IOP at last follow up; of these, 13 eyes (30% of total eyes) required a further IOP lowering procedure.

Conclusions: : Repeat SLT was successful in nearly 45% of our study sample. A significant number of patients required a further IOP lowering procedure.
