Modifications of Surgical Techniques in Glaucoma Drainage Devices

  • Kleyton Barella

Glaucoma drainage devices (GDDs) are used to redirect the aqueous humor to a subconjunctival/subtenon extraocular reservoir in order to reduce the intraocular pressure (IOP). GDDs are frequently implanted in eyes with a previous trabeculectomy, uveitis, and presence of upper perilimbic conjunctival scar or neovascular glaucoma. A GDD consists of a tube that connects the intraocular space directly to the subtenon space or to a valved or non-valved plate. These plates are available in various materials, sizes, and designs and are sutured to the sclera between the rectus muscles [1].
