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 ...
The word glaucoma comes from the Ancient Greek word γλαυκός (glaukós), meaning 'gleaming, blue-green, gray'. There are different types of glaucoma, but the most common are called open-angle glaucoma and closed-angle 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.
Glaucoma is a genus of freshwater ciliates in the Oligohymenophorea. Cells in this genus are between 30–150 μm long, and have three membranelles (structures formed from multiple modified cilia ) that surround the oral cavity. [ 1 ]
[4] [19] Another found that PEX was present in 6% of an "open-angle glaucoma" group. [20] Pseudoexfoliation syndrome is considered to be the most common of identifiable causes of glaucoma. [5] If PEX is diagnosed without glaucoma, there is a high risk of a patient subsequently developing glaucoma. [3] Country and region. Prevalence of PEX ...
Glaucoma medication is divided into groups based on chemical structure and pharmacologic action. The goal of currently available glaucoma therapy is to preserve ...
Over many years, glaucoma has been defined by an intraocular pressure of more than 20 mm Hg. Incompatible with this (now obsolete) definition of glaucoma was the ever larger number of cases that have been reported in medical literature in the 1980s and 1990s who had the typical signs of glaucomatous damage, like optic nerve head excavation and thinning of the retinal nerve fiber layer, while ...
