Contrast-enhanced intraoperative optical coherence tomography.

Area of Science:

• Ophthalmology
• Medical Imaging
• Surgical Technology

Background:

• Optical Coherence Tomography (OCT) offers high-resolution anatomical detail crucial for ophthalmic surgery.
• Contrast agents enhance diagnostic capabilities in medical imaging like CT and MRI.
• The use of OCT contrast agents in ophthalmology remains underdeveloped.

Purpose of the Study:

• To investigate the novel application of triamcinolone as an OCT contrast agent.
• To improve visualization of tissue interfaces and planes during intraoperative OCT imaging.
• To explore the potential of enhanced intraoperative OCT for surgical guidance.

Main Methods:

• Described the use of triamcinolone as an OCT contrast agent.
• Applied intraoperative OCT with triamcinolone during ophthalmic procedures.
• Evaluated the visibility of tissue interfaces, specifically posterior hyaloid insertion points.

Main Results:

• Triamcinolone effectively served as an OCT contrast agent.
• Improved visibility of critical tissue interfaces and surgical planes was achieved.
• Demonstrated potential for enhanced intraoperative OCT imaging.

Conclusions:

• Triamcinolone is a viable OCT contrast agent for intraoperative use in ophthalmology.
• This technique can significantly improve visualization during surgery.
• Potential for enhanced image-guided surgery and advanced OCT applications exists.
