Recent advances in trabeculectomy technique

Curr Opin Ophthalmol. 2005 Apr;16(2):107-13. doi: 10.1097/01.icu.0000156138.05323.6f.

Abstract

Purpose of review: Trabeculectomy is an effective operation for lowering intraocular pressure. However, success is limited by complications such as infection, hypotony, and scarring.

Recent findings: These complications, which are increased by antifibrotic use, can be reduced with attention to surgical technique. We highlight the benefit of sub-Tenon anaesthesia, careful choice of the surgical site, fashioning of the scleral flap to produce diffuse aqueous flow, and better intraocular pressure control, maintenance of intraocular pressure, a formed anterior chamber, with outflow control during surgery using an infusion, optimal method of antimetabolites application, new adjustable sutures, and corneal-conjunctival closure techniques.

Summary: These techniques reduce hypotony, producing a diffuse noncystic bleb with long-term pressure control.
