What is glaucoma?

What is glaucoma?

Impaired eye fluid: Glaucoma is a condition in the inside of the eye, in which the fluid (aqueous humor) cannot get out at a low enough pressure to prevent the pressure from causing loss of the nerves and blood vessels at the back of the eye which causes vision to be lost. Measured will be eye pressure, corneal thickness, visual field, and disc structure. These are all part of the diagnosis. ...Read more

Glaucoma (Definition)

A condition that causes damage to your eye's optic nerve and gets worse over time. It's often linked to a buildup of pressure inside your eye. Without treatment, glaucoma can cause total permanent blindness ...Read more

Does glaucoma hurt?

Does glaucoma hurt?

It can: There are 2 main types of glaucoma, closed-angle (acute) and open-angle (chronic). Acute glaucoma is less common, but can present with sudden eye pain due to an increase in intraocular pressure. Chronic glaucoma commonly does not present with eye pain as the process of the disease is more gradual. Be sure to see your doctor if you are experiencing any eye symptoms or are concerned about glaucoma. ...Read more

Is glaucoma painful?

Is glaucoma painful?

Not ordinarily: The two main types of glaucoma are open angle ; angle closure. The former is painless and progressive, if not stabilized. The latter also tends to be slow and progressive, but usually gradually closes the drainage angle of the eye. If acute angle closure of the angle occurs, considerable pain results and loss of vision ensues, if not urgently treated by medicine and laser or incisional surgery. ...Read more

What causes glaucoma?

Mostly unknown: A few cases of glaucoma occur due to trauma, inherited problems and anatomical underpinnings. The majority - 'open angle glaucoma'- is largely age related with no known cause. ...Read more

Is glaucoma inherited?

Some are: There are many different types of glaucoma, some caused secondarily through trauma or other diseases. But there are some type of glaucoma where genetics are involved but not 100%. In other words just because your parents have it doesn't mean you have to get it. However, risk is certainly higher.... ...Read more

How is glaucoma defined?

3 factors: Glaucoma is an optic nerve problem, usually consisting of high pressure in the eye, evidence of damage to the nerve on exam and on testing (oct or HRT test) and evidence of damage to the peripheral or 'near central' vision on a visual field test. ...Read more

How is glaucoma detected?

Eye exam and testing: Usually a glaucoma evaluation is triggered when the optic nerve appears large, the eye pressure is measured high, the peripheral vision is diminished, or the front part of the eye appears narrow. At that point a full glaucoma workup is performed including imaging of the optic nerves and visual fields to confirm progressive damage. ...Read more

How is glaucoma diagnosed?

Eye exam: Through a combination of tests including structural (disc photo, optical coherence tomography) and visual function (visual field) that demonstrates progressive damage to the optic nerve over time. Typically, measuring intraocular pressure is involved since it is our main treatable risk factor for worsening disease. ...Read more

What would cause glaucoma?

Many: Primary causes vs. Secondary causes. Genetic predisposition. Anything that damages the eye so that the level of eye pressure is harmful to the optic nerve and causes loss of retinal ganglion cells. The eye drain could be damaged, ocular perfusion could be affected, etc. ...Read more

Who is at risk for glaucoma?

Everyone: Technically, glaucoma affects babies to adults. Typically older age is a higher risk. Certain ethnicities can be a higher risk for various types of glaucoma. Family history of glaucoma increases the risk. Glaucoma has many secondary causes as well. ...Read more

What are symptoms of glaucoma?

Loss of side vision: Most glaucoma is asymptomatic. Acute angle closure glaucoma is associated with pain, blurred vision, nausea and a red eye. Open angle glaucoma is not symptomatic until late in the progression of the disease. This fact is why routine eye exams are recommended to detect the disease early in its course before irreversible damage to the optic nerve and the vision has occurred . ...Read more
