Objective:
To evaluate the effectiveness of the femtosecond laser image-guided high-precision trabeculotomy (FLIGHT) technique using multiple drainage channels to enhance aqueous outflow.
Key Findings:
- Eyes with 2 channels showed an average outflow facility of 0.39±0.13 µL/min/mmHg compared to 0.27±0.01 µL/min/mmHg for single channel eyes.
- The increase in outflow facility with dual channels was statistically significant.
- Immunofluorescent imaging indicated improved fluid movement in regions of low flow when multiple channels were created.
Interpretation:
The results suggest that targeting multiple sites within the outflow pathway may enhance fluid dynamics and improve intraocular pressure control.
Limitations:
- The study was limited to an ex vivo model, which may not fully replicate in vivo conditions, and requires confirmation in clinical settings.
Conclusion:
The FLIGHT procedure offers a precise, incision-free approach to trabeculotomy, potentially improving glaucoma treatment by allowing tailored interventions based on individual anatomy, which could significantly impact clinical practice.
