title: Long-term outcomes of selective laser trabeculoplasty (SLT) treatment in pigmentary glaucoma patients.
abstract: OBJECTIVE
  The aim of the present study was to assess the long-term efficacy of selective laser trabeculoplasty (SLT) treatment in patients suffering from pigmentary glaucoma (PG).
  
  
  METHODS
  Retrospective chart review of eyes suffering from PG that underwent SLT between January 1, 2005 and December 31, 2006. The primary outcome measure was time to failure after SLT treatment. Failure after SLT was defined as any 1 or more of the following: <20% intraocular pressure reduction, change in the medical treatment, performance of a further SLT treatment, and the patient being sent for surgery. All patients were treated over 180 degrees with SLT.
  
  
  RESULTS
  Thirty eyes of thirty patients were identified. The average time to failure after SLT was 27.4 months. The success rate after 12 months was 85%, after 24 months 67%, after 36 months 44%, and after 48 months 14%.
  
  
  CONCLUSIONS
  The long-term effects of SLT in PG when eyes were treated over 180 degrees seem to be low.
