Mark A. Latina, MD
A review of two studies that hold important implications for SLT treatment.
Comparing SLT with ALT
Karim F. Damji, MD
Research indicates that SLT appears to be equivalent to ALT in lowering IOP at all time points.
Selective Laser Trabeculoplasty: A New Approach to Open-Angle Glaucoma Management
Madhu Nagar, MBBS FRCS
Presented at the AAO conference in October, 2002
Purpose: To evaluate the safety and efficacy of IOP reduction with SLT.
Methods: 207 patients enrolled. Group1: Medically uncontrolled open-angle glaucoma (OAG) and ocular hypertension (OHT). Group 2: Newly diagnosed patients of OAG and OHT.SLT (90, 180 and 360 degrees) was carried out using Coherent Selecta 7000; frequency doubled Nd:YAG laser. A/C reaction, IOPs and peripheral anterior synechiae were observed posttreatment.
Results: Group 1: Mean IOP reduction as 25.6% for OAG and 33% for OHT. Newly diagnosed OAG and OHT patient receiving SLT as first-line treatment also responded well, showing 28.5% and 29.5% drop, respectively.
Conclusion: SLT is a safe and effective outpatient procedure and is easy to perform. The effect is sustained within the duration of the trial to date (26 months).
