viscocanalostomy

viscocanalostomy

(vis'kō-kan-ăl-os'tŏ-mē),
A procedure to treat glaucoma in which the canal of Schlemm is dilated by injection of viscoelastic.
[visco (elastic) + canal + -stomy]

viscocanalostomy  

A type of non-penetrating filtration surgery aimed at lowering intraocular pressure by dissecting a superficial scleral flap and excising a deeper partial-thickness scleral flap below, leaving a thin membrane consisting of trabeculum and Descemet's membrane, through which the aqueous humour diffuses. It then drains from the anterior chamber into the subconjunctival space or through Schlemm's canal into which a high-density viscoelastic substance has been injected. The superficial flap is sutured in place at the end of the procedure. Intraocular pressure reduction is not usually as large as with trabeculectomy. See filtration surgery.

There are many types of intraocular surgeries such as phacoemulsification, trabeculectomy, deep sclerotomy, viscocanalostomy, holmium laser sclerostomy, deep anterior lamellar keratoplasty, endothelial keratoplasty, intracorneal ring segment implantation, and pars plana vitrectomy, that are known to result in DMD.
Other surgical options may also be considered for patients unsuitable for medical therapy, such as tube shunts, viscocanalostomy (causing dilation of Schlemm's canal) or a deep sclerectomy (resulting in removal of the inner wall of Schlemm's canal and the juxta-canalicular trabecular meshwork alleviating the majority of outflow resistance).
