Answer

Argon laser trabeculoplasty (ALT): This procedure may have minimal effect because the intraocular pressure (IOP) is already in the reference range.

Selective laser trabeculoplasty (SLT): SLT targets pigment-producing cells in the trabecular meshwork with less tissue destruction and scarring compared with ALT.

Trabeculectomy: If medical therapy is ineffective, adjunctive antimetabolite therapy likely is needed for postoperative IOP to be in the single digits. A higher risk of hypotony and endophthalmitis exists when targeting extremely low pressures that may be needed to retard or prevent progression of field loss.
