Hyaluronidase injection for improved tissue dissection in Baerveldt tube surgery

Abstract

Purpose

To describe a novel technique for tissue dissection during Baerveldt tube surgery.

Methods

We present a technique for posterior dissection of conjunctiva and Tenon tissue for the placement of a glaucoma drainage device. Hyaluronidase is used in the early stages of surgery in order to minimize tissue trauma and facilitate easy dissection even through existing adhesions and conjunctival scarring.

Results

The technique facilitates convenient dissection through tissues. We did not experience any intraoperative or postoperative complications.

Conclusions

The described technique has substantial advantages for Baerveldt tube surgery, specifically in cases of previous ocular surgery and subsequent conjunctival scarring. It is safe and easy to perform, and should be considered in cases of glaucoma drainage device implantation surgeries.
