Laser trabeculoplasty may be more effective than older glaucoma medications for controlling intraocular pressure. However, trabeculectomy surgery is more effective, and more research is needed on newer treatments.

Area of Science:

  • Ophthalmology
  • Glaucoma Research
  • Laser Therapy

Background:

  • Open-angle glaucoma (OAG) is a leading cause of global blindness.
  • The optimal placement of laser trabeculoplasty in OAG treatment remains unclear.

Purpose of the Study:

  • To systematically review the effects of laser trabeculoplasty for OAG.
  • To compare laser trabeculoplasty with no intervention, medical treatment, and surgery.
  • To evaluate different laser trabeculoplasty techniques.

Main Methods:

  • Systematic review of randomized controlled trials.
  • Searched multiple databases (CENTRAL, MEDLINE, EMBASE, LILACS) and contacted experts.
  • Included trials comparing laser trabeculoplasty to other interventions or different laser modalities.

Related Experiment Videos

Main Results:

  • Included 19 trials with 2137 participants; only 5 were high quality.
  • Laser trabeculoplasty showed a lower risk of glaucoma progression than no intervention in early OAG.
  • Compared to older medications, laser trabeculoplasty reduced uncontrolled intraocular pressure (IOP); trabeculectomy was more effective than laser trabeculoplasty in controlling IOP.

Conclusions:

  • Laser trabeculoplasty is more effective than pre-1990s medications for OAG at two years.
  • Trabeculectomy demonstrates superior IOP control compared to laser trabeculoplasty.
  • Further research is needed on newer medications, surgical techniques, cost-effectiveness, and laser trabeculoplasty in specific patient groups.
