  2. Minimally invasive glaucoma surgery - Wikipedia

    en.wikipedia.org/wiki/Minimally_invasive...

    Micro-invasive glaucoma surgery ( MIGS) is the latest advance in surgical treatment for glaucoma, which aims to reduce intraocular pressure by either increasing outflow of aqueous humor or reducing its production. MIGS comprises a group of surgical procedures which share common features. [ 1] MIGS procedures involve a minimally invasive ...

  3. Glaucoma surgery - Wikipedia

    en.wikipedia.org/wiki/Glaucoma_surgery

    Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few that lower IOP by decreasing the production of ...

    en.wikipedia.org/wiki/Ocular_tonometry

    Ocular tonometry. Tonometry is the procedure that eye care professionals perform to determine the intraocular pressure (IOP), the fluid pressure inside the eye. It is an important test in the evaluation of patients at risk from glaucoma. [ 1] Most tonometers are calibrated to measure pressure in millimeters of mercury ( mmHg ), with the normal ...

    en.wikipedia.org/wiki/Secondary_glaucoma

    Secondary glaucoma is a collection of progressive optic nerve disorders associated with a rise in intraocular pressure (IOP) which results in the loss of vision. In clinical settings, it is defined as the occurrence of IOP above 21 mmHg requiring the prescription of IOP-managing drugs. [1] It can be broadly divided into two subtypes: secondary ...

  6. Trabeculectomy - Wikipedia

    en.wikipedia.org/wiki/Trabeculectomy

    Trabeculectomy is a surgical procedure used in the treatment of glaucoma to relieve intraocular pressure by removing part of the eye 's trabecular meshwork and adjacent structures. It is the most common glaucoma surgery performed and allows drainage of aqueous humor from within the eye to underneath the conjunctiva where it is absorbed.
