Repeat 360° selective laser trabeculoplasty (SLT) effectively lowers intraocular pressure (IOP) in open-angle glaucoma patients previously treated with SLT. This repeat procedure offers sustained IOP control comparable to the initial treatment, with no observed safety concerns.

Area of Science:

  • Ophthalmology
  • Glaucoma Research
  • Laser Therapy

Background:

  • Open-angle glaucoma (OAG) management often requires sustained intraocular pressure (IOP) reduction.
  • Selective laser trabeculoplasty (SLT) is a common procedure for IOP control.
  • The efficacy of repeat SLT in patients with prior successful treatment is an area of ongoing investigation.

Purpose of the Study:

  • To evaluate the IOP-lowering effectiveness of repeat 360° SLT in OAG patients.
  • To assess the durability of IOP control after a second 360° SLT procedure.
  • To compare the outcomes of repeat SLT with initial SLT in the same patient cohort.

Main Methods:

  • Retrospective chart review of 38 eyes from 38 OAG patients.
  • Patients had undergone two successive 360° SLT treatments, with the first deemed successful for at least 6 months.

  • IOP measurements were compared pre- and post-repeat SLT at multiple time points up to 24 months.

    • Main Results:

    • Initial SLT lowered mean baseline IOP from 21.6 mmHg to a range of 15.9-18.6 mmHg through 24 months.
    • Repeat SLT lowered mean baseline IOP from 19.1 mmHg to a range of 14.7-17.0 mmHg through 24 months.
    • Kaplan-Meier analysis indicated longer median survival time for repeat SLT compared to initial SLT; no safety issues were reported.

    Conclusions:

    • Repeat 360° SLT is effective in restoring IOP control in OAG patients.
    • The IOP-lowering effect of repeat SLT is comparable to that achieved by the initial SLT procedure.
    • Repeat SLT represents a safe and viable option for sustained IOP management in OAG.
