Anterior Segment OCT Biomarkers in Early Postoperative Phase Show No Predictive Value for Secondary Interventions Following Preserflo MicroShunt Surgery
To evaluate the predictive value of anterior segment optical coherence tomography (AS-OCT) parameters, specifically bleb wall thickness (BWT) and total bleb height (TBH), for secondary interventions after Preserflo MicroShunt (PM) surgery, and to assess their correlation with AS-OCTA-derived bleb vessel density (BVD).
Key Findings:
10 out of 23 patients required secondary interventions between 4 and 48 weeks post-PM implantation.
No significant association was found between BWT/TBH and future secondary interventions at 1, 2, and 4 weeks post-surgery (p-values: 0.217/0.878, 0.670/0.528, 0.171/0.430 respectively), indicating consistent results across these time points.
No correlation was observed between BWT/TBH and BVD.
Interpretation:
Structural AS-OCT parameters BWT and TBH in the early postoperative phase do not predict secondary interventions after PM implantation, suggesting that further research is needed to explore the reliability of other biomarkers like BVD.
Limitations:
Small sample size of 23 patients limits generalizability.
Short follow-up duration may not capture long-term outcomes.
Potential biases due to the single-center study design.
Conclusion:
AS-OCT-based parameters BWT and TBH are not predictive of secondary interventions after PM surgery; further research with larger cohorts is needed to validate these findings.
