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 approach ...
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 ...
Glaucoma. Acute angle closure glaucoma of a person's right eye (shown at left). Note the mid-sized pupil, which is non- reactive to light, and redness of the white part of the eye. Glaucoma is a group of eye diseases that lead to damage of the optic nerve, which transmits visual information from the eye to the brain.
Trabeculectomy is the most common invasive glaucoma surgery. It is highly effective in the treatment of advanced glaucoma as demonstrated in major glaucoma studies. [citation needed] Even if a prior trabeculectomy has failed a second trabeculectomy can be performed at a different site. If scarring is the main reason, anti-fibrotic and anti ...
Pigment dispersion syndrome ( PDS) is an eye disorder that can lead to a form of glaucoma known as pigmentary glaucoma. It takes place when pigment cells slough off from the back of the iris and float around in the aqueous humor. Over time, these pigment cells can accumulate in the anterior chamber in such a way that they begin to clog the ...
Anterior chamber paracentesis. Anterior chamber paracentesis ( ACP) is a surgical procedure done to reduce intraocular pressure (IOP) of the eye. The procedure is used in management of glaucoma and uveitis. It is also used for clinical diagnosis of infectious uveitis.
Primary juvenile glaucoma is a subtype of primary congenital glaucoma [2] that develops due to ocular hypertension and is diagnosed between three years of age and early adulthood. [3] [4] It is caused due to abnormalities in the anterior chamber angle development that obstruct aqueous outflow in the absence of systemic anomalies or other ocular ...
It facilitates the removal of the cataractous lens. [1] A sector iridectomy, also known as a complete iridectomy or total iridectomy, is the surgical removal of a complete radial section of the iris extending from the pupillary margin to the root of the iris. [2] A key-hole pupil is left by the removal of a wedge-shaped section of iris.
