XEN-augmented Baerveldt: A New Surgical Technique for Refractory Glaucoma

Area of Science:

• Ophthalmology
• Glaucoma Surgery
• Medical Devices

Background:

• Glaucoma drainage devices are typically for refractory glaucoma.
• Existing devices carry risks of sight-threatening complications.
• Current methods to prevent hypotony with Baerveldt tubes are limited.

Purpose of the Study:

• To introduce a new surgical technique for refractory glaucoma.
• To combine Baerveldt and XEN tubes in a single procedure.
• To mitigate complications associated with glaucoma drainage devices.

Main Methods:

• The Baerveldt implant was placed in the superotemporal quadrant.
• A scleral flap was created, and the XEN tube was inserted into the Baerveldt tube's lumen.
• The combined tube was secured and covered with the scleral flap.

Main Results:

• The technique involves creating a double tube by connecting XEN and Baerveldt implants.
• This combined approach aims to minimize hypotony and corneal disease.
• The procedure was described in detail, highlighting its integration of both devices.

Conclusions:

• This combined Baerveldt and XEN tube technique is straightforward.
• The new method may enhance the safety of surgeries for refractory glaucoma.
• It offers a potential improvement in managing complex glaucoma cases.
