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.
