Ophthalmology Management

Objective:

To evaluate the impact of selective laser trabeculoplasty (SLT) on structural glaucomatous progression as measured by optical coherence tomography (OCT).

Key Findings:

Prior to SLT, significant progressive thinning of RNFL thickness was observed.
After SLT, rates of change for all evaluated OCT parameters were no longer significantly different from zero.
Significant slowing of average RNFL thickness, superior RNFL, and cup-to-disc ratio progression was noted post-SLT.
A modest but statistically significant reduction in mean IOP was observed following SLT.

Interpretation:

SLT may not only lower IOP but also slow the structural progression of glaucomatous damage over time, as evidenced by OCT measurements.

Limitations:

Small sample size of 25 eyes.
Retrospective nature of the study may limit causal inferences.

Conclusion:

SLT is a meaningful therapeutic option that may help preserve the optic nerve and should be considered for earlier use in glaucoma management.
