Four-dimensional Microscope-Integrated Optical Coherence Tomography to Visualize Suture Depth in Strabismus Surgery.

Area of Science:

• Ophthalmology
• Medical Imaging
• Surgical Technology

Background:

• Strabismus surgery, specifically lateral rectus resection, requires precise control of suture placement.
• Intraoperative visualization of surgical depth is crucial for accurate muscle manipulation and minimizing complications.

Purpose of the Study:

• To evaluate the utility of swept-source microscope-integrated optical coherence tomography (SS-MIOCT) for real-time intraoperative visualization of suture depth during lateral rectus resection.

Main Methods:

• The study utilized SS-MIOCT, a novel imaging system providing live four-dimensional (3D across time) intraoperative views.
• The technology was applied during lateral rectus resection to visualize critical surgical steps involving needle placement.

Main Results:

• SS-MIOCT successfully visualized needle depth during partial and full-thickness muscle passes.
• Scleral passes were also clearly visualized, demonstrating the system's capability to monitor suture placement throughout the procedure.

Conclusions:

• SS-MIOCT offers direct, real-time visualization of suture depth, enhancing surgical precision in strabismus procedures.
• This technology has the potential to improve outcomes in lateral rectus resection by providing critical intraoperative feedback.
