Purpose: Selective laser trabeculoplasty (SLT) is a new technique developed to selectively target pigmented trabecular meshwork. We investigated the safety and efficacy of this technique to lower intraocular pressure (IOP).

Methods: Fifty nine eyes with uncontrolled open angle glaucoma (OAG) with prior medical therapy were treated with the Coherent Selecta 7000 TM (Coherent Inc., Palo Alto, CA), a frequency doubled Q switched Nd:Yag laser. Approximately 110 laser spots were applied over 360° of the trabecular meshwork. Efficacy was determined 5 weeks, 1 month, 3 months, 6 months and one year after the procedure.

Results: The average preoperative IOP was 25.05mmHg .Mean post operative IOP (at one year) was 15.76mmHg. Mean percentage reduction was 32.43% at 3 months after operation, 32.51% at six months and 33.51% at one year. Transient post operative pressure spike of 5mmHg or greater resolved in 24 hours was observed in 5 eyes.

Conclusion: SLT appears to be an effective and safe technique for lowering IOP and could be an alternative to Argon laser trabeculoplasty.
