Primary Outcome Measures:
  • The amount of pressure lowering after EXTERNAL MICROPULSE DIODE LASER TRANSSCLERAL TRABECULOPLASTY (EMDLT) treatment.

Secondary Outcome Measures:
  • Study of safety of EXTERNAL MICROPULSE DIODE LASER TRANSSCLERAL TRABECULOPLASTY (EMDLT) treatment

Estimated Enrollment: 30
Study Start Date: June 2006
Estimated Study Completion Date: December 2008
Detailed Description:

Micropulse diode laser trabeculoplasty applied through a gonioscopy len has been shown to be effective in lower the pressure for patients with primary open angle glaucoma (POAG). We believe that applied externally, the contact diode micropulse laser will be effective in lowering intraocular pressure for patients with advance open angle glaucoma with minimal side effects
