Laser can be used as primary or adjunctive treatment. It is indicated in cases of noncompliance with medications or if the patient is on maximum tolerated medical therapy and needs further intraocular pressure reduction.

The following are laser options that may be used for primary open-angle glaucoma:

  • Argon laser trabeculoplasty (ALT)
  • Selective laser trabeculoplasty (SLT)
  • Micropulse diode laser trabeculoplasty (MDLT)
