Glaucoma is a disease that damages your eye's optic nerve . (aao.org)
People with "normal tension glaucoma" have eye pressure that is within normal ranges, but show signs of glaucoma, such as blind spots in their field of vision and optic nerve damage. (aao.org)
Glaucoma is a group of eye diseases that can cause vision loss and blindness by damaging a nerve in the back of your eye called the optic nerve. (nih.gov)
Whether you develop glaucoma depends on how much pressure your optic nerve-the bundle of 1.2 million nerve fibers that transmits images from the eye to the brain-can take without being damaged. (healthywomen.org)
Research is continuing on this form of glaucoma, which is thought to be related to poor blood flow to the optic nerve. (healthywomen.org)
Glaucoma is a group of optic neuropathies with typical optic nerve head cupping and apoptosis of retinal ganglion cells and their axons with respective vision loss [1] . (aao.org)

A study identified unilateral blindness in 15.5% of patients with primary open-angle glaucoma (POAG) after 7.5±5.5 years [3] . (aao.org)
This study estimates the prevalence and incidence rates of primary open -angle glaucoma (POAG) as well as risk factors based on a dataset from the largest German health insurance company. (biomedcentral.com)
Therefore early detection and appropriate treatment is essential [ 3 ], which can be facilitated by better knowledge of the prevalence and incidence of glaucoma, and the risk factors associated with primary open-angle glaucoma (POAG), which is the most common type of glaucoma [ 1 ]. (biomedcentral.com)
In 2010, an estimated 44.7 million people worldwide suffered from primary open-angle glaucoma (POAG), and 4.5 million were blind, making POAG the most common type of glaucoma [ 4 ]. (biomedcentral.com)
OAG and ACG can also be classified as primary (primary open-angle glaucoma [POAG] or primary angle-closure glaucoma [PACG], respectively) or SG, depending on the cause. (globaldata.com)
Studies have suggested that the prevalence of glaucoma (especially POAG) has been steadily increasing over the past decade but ascertaining this is difficult due to most cases remaining undiagnosed. (globaldata.com)

From there, it flows along the underside of the iris, up through the pupil and then out through the drainage angle. (allaboutvision.com)
In angle-closure forms, the aqueous can't leave the eye because the iris is blocking the drainage angle. (allaboutvision.com)
The drainage angle is a delta-shaped notch of space that surrounds the outside edge of the iris. (allaboutvision.com)
Primary Glaucoma: Primary acute closed-angle glaucoma results from a buildup of fluid in the eye because the distance between the iris and the drainage system has been closed, stopping fluid from draining from the eye. (cnib.ca)
Primary Glaucoma: Chronic angle closure glaucoma also involves a narrowing of space between the iris and the drainage system, but it occurs more gradually than in the acute form of the condition (and can take weeks or even years). (cnib.ca)
This type happens when someone's iris is very close to the drainage angle in their eye. (aao.org)
The iris can end up blocking the drainage angle. (aao.org)
In this type of glaucoma, the outer edge of the iris (the colored part of your eye) blocks fluid from draining out of the front of the eye. (nih.gov)
Pigmentary glaucoma happens when the pigment (color) from your iris (the colored part of your eye) flakes off and blocks fluid from draining out of your eye. (nih.gov)
The fluid travels from the gland through the pupil into the anterior chamber, exiting at an angle where the cornea and the iris meet. (healthywomen.org)
In this most common form of glaucoma, the angle where the cornea and the iris meet is open, but the aqueous humor fluid passes too slowly through the meshwork drain. (healthywomen.org)
Glaucoma occurs when grains of pigment from the back of the iris flake off into the aqueous humor, eventually clogging the drainage meshwork and raising eye pressure. (healthywomen.org)
In some but not all people, this growth pushes the iris forward, narrowing the angle. (msdmanuals.com)
In people with narrow angles, the distance between the iris at the pupil and the lens is also very narrow. (msdmanuals.com)
Pressure from the continued secretion of aqueous into the posterior chamber by the ciliary body pushes the peripheral iris anteriorly (causing a forward-bowing iris called iris bombe), closing the angle. (msdmanuals.com)
Pupillary dilation (mydriasis) can push the iris into the angle and precipitate acute angle-closure glaucoma in any person with narrow angles. (msdmanuals.com)
Contraction of a neovascular membrane (eg, in PDR) or inflammatory scarring can pull the iris into the angle. (msdmanuals.com)
With angle-closure glaucoma, the iris is not as wide and open as it should be. (glaucoma.org)
Treatment of angle-closure glaucoma usually involves either laser or conventional surgery to remove a small portion of the bunched-up outer edge of the iris. (glaucoma.org)
In cases of acute angle closure glaucoma, the iris may bow forward so much that it cuts off your eye's angle completely. (glaucoma.org)
This type of glaucoma occurs when the drainage angle is completely blocked, often by the eye's iris. (cseyeclinic.com)
The block occurs at the angle of the anterior chamber that is formed by the junction of the cornea with the iris. (surgeryencyclopedia.com)
Eventually the fluid returns to the general circulation of the body, first passing through a space between the iris and the lens, then flowing into the anterior chamber of the eye and down the angle, where the trabecular meshwork is located. (surgeryencyclopedia.com)
The anatomical anomalies that make an individual susceptible to an angle closure are, for example, an iris that is bent forward in the anterior chamber (front) of the eye, a small anterior chamber of the eye, and a narrow entrance to the angle of the eye. (surgeryencyclopedia.com)
Angle-closure glaucoma (ACG) is a condition in which the iris is apposed to the trabecular meshwork at the angle of the anterior chamber of the eye. (medscape.com)
In either case, the position of the iris causes the normally open chamber angle to close. (medscape.com)
Increased iris thickness, as measured by anterior segment optical coherence tomography (OCT), is another risk factor for angle-closure glaucoma in the Asian population. (medscape.com)
Increased iris thickness and association with primary angle closure glaucoma. (medscape.com)
It can be prevented or controlled by treating its underlying cause, a narrowing of the eye's drainage angle, a structure at the junction of the iris and cornea. (seevividly.com)
Narrow angle glaucoma is caused by a blockage of the drainage of aqueous humor from the anterior chamber into the posterior chamber through the angle of the eye (the structure that contains the iris and trabecular meshwork and is situated between the iris and cornea). (seevividly.com)
In narrow angle glaucoma , the angle can become closed by the iris blocking it. (seevividly.com)
It can also be caused by congenital conditions such as when the angle is abnormally large, when the iris is congenitally large, or in some cases when the lens is smaller than normal. (seevividly.com)
The position of the iris relative to the angle is also thought to be a factor in glaucoma. (seevividly.com)
Dilation is more risky in patients who have a narrow angle, where the iris (colored part of the eye) is very close to the cornea (clear window at the front of the eye) . (aao.org)
If your narrow angle poses such a risk, your ophthalmologist will usually perform a laser peripheral iridotomy, which makes a microscopic hole in the iris so the pressure will not go up when the eye is dilated. (aao.org)
Angle-closure glaucoma occurs when the space between the iris and cornea narrows , trapping fluid in the eye. (celebrationeyecare.com)
This type of glaucoma is marked by the drain space between your cornea and iris narrowing. (jeffreyjyocumod.com)
Ciliary body melanomas can push the iris diaphragm anteriorly, or they can infiltrate the trabecular meshwork, producing acute angle closure. (medscape.com)

This is the most common type of glaucoma. (aao.org)
In the most common type of glaucoma, the drainage "angle" (where fluids in the eye drain) is open but working less efficiently, much like an air filter that gathers dust over time and eventually becomes too clogged to work properly. (cseyeclinic.com)
However, in some situations cataracts can make a less common type of glaucoma worse, as they can cause the pressure in the eye to rise. (specsavers.co.uk)

Neovascular glaucoma happens when the eye makes extra blood vessels that cover the part of your eye where fluid would normally drain. (nih.gov)

Regular checkups are still important though, because a chronic form of glaucoma could still occur. (glaucoma.org)
