filtration surgery

A surgical procedure aimed at lowering the intraocular pressure by producing an outflow of aqueous humour through a drainage passage created in the sclera between the anterior chamber and the subconjunctival space. See glaucoma surgery; deep sclerectomy; trabeculectomy; viscocanalostomy.

While descriptions of surgical management in this text are centred on more common types of glaucoma, such as paediatric, angle closure and laser approaches to management, not to mention how to deal with concurrent cataract extraction in glaucoma filtration surgery, the text does not shy away from discussing more modern techniques such as the minute stent procedure, which aims to increase aqueous outflow at Schlemm's canal in order to reduce intraocular pressure, to cyclodestructive approaches which are reserved for patients who are unresponsive to even surgical methods of glaucoma management.

INDICATIONS: Glaucoma drainage device implantation is usually reserved for cases with refractory glaucoma, or those unlikely to respond successfully to a conventional filtration surgery. The Indications for GDD implantation include the following:

Conventional glaucoma filtration surgery have limited role in management of glaucoma after parsplana vitrectomy & silicone oil injection, so adjuvants like Mitomycin-C & 5-Flurouracil are used to prevent fibrosis & failure of trabeculectomy (20).
