Three techniques for 360-degree gonioscopy-assisted transluminal trabeculotomy with iTrack advance

Area of Science:

• Ophthalmology
• Surgical Innovation

Background:

• 360-degree gonioscopy-assisted transluminal trabeculotomy (GATT) is an established angle-based surgical intervention for reducing intraocular pressure (IOP).
• Traditional GATT techniques often involve manual threading of microcatheters or sutures through Schlemm's canal, which can be technically demanding.
• The iTrack Advance system offers an improved method for microcatheter advancement in GATT procedures.

Observation:

• Three distinct surgical techniques for performing 360-degree GATT utilizing the iTrack Advance are detailed.
• Technique 1 requires microcatheter tip retrieval and an assistant for gonioprism stabilization.
• Technique 2 necessitates microcatheter tip retrieval but does not require an assistant.
• Technique 3 eliminates the need for microcatheter tip retrieval and gonioprism assistance.

Findings:

• All three presented techniques enable the successful completion of 360-degree GATT with the iTrack Advance.
• These variations streamline the procedure by avoiding manual threading of instruments through Schlemm's canal.
• The iTrack Advance facilitates efficient microcatheter navigation via a slider mechanism.

Implications:

• The described techniques offer surgeons greater flexibility and efficiency in performing GATT.
• These advancements may lead to wider adoption and improved outcomes for patients requiring IOP reduction.
• Simplifying the GATT procedure can potentially reduce surgical time and complexity.
