Fibrin glue-assisted glaucoma drainage device surgery

Area of Science:

• Ophthalmology
• Surgical Innovation
• Glaucoma Management

Background:

• Glaucoma drainage device (GDD) implantation is a common surgical procedure for managing refractory glaucoma.
• Traditional suture materials are used for securing the device and closing surgical sites.
• Exploring alternative materials like fibrin glue can potentially improve surgical outcomes and patient recovery.

Purpose of the Study:

• To evaluate the efficacy and safety of using Tisseel fibrin glue as a substitute for sutures in specific portions of glaucoma drainage device surgery.
• To compare outcomes between GDD implantation using fibrin glue versus traditional suture materials.

Main Methods:

• Retrospective case-control study comparing 28 GDD implantations with traditional sutures to 14 GDD implantations using Tisseel fibrin glue.
• Fibrin glue was utilized for conjunctival closure, securing the pericardium patch graft, and tube-to-sclera fixation.
• Outcomes assessed included intraocular pressure (IOP), need for glaucoma medications, complication rates, postoperative conjunctival inflammation, and surgical time over a three-month follow-up.

Main Results:

• No significant differences in intraocular pressure (IOP) or need for glaucoma medications were observed between the fibrin glue and suture groups.
• Postoperative complication rates were similar in both groups.
• Tisseel fibrin glue significantly reduced surgical time (15.0 min vs. 25.9 min) and resulted in less pronounced postoperative conjunctival inflammation compared to sutures.

Conclusions:

• Tisseel fibrin glue serves as a safe and effective substitute for certain sutures in glaucoma drainage device surgery.
• Its use is associated with reduced operative time and improved postoperative conjunctival inflammation, with no adverse impact on IOP control or complication rates.
• Further research is warranted to fully elucidate the role of fibrin glue in GDD implantation procedures.
