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

Glaucoma (Definition)

Glaucoma refers to a group of eye conditions that lead to damage to the optic nerve, the nerve that carries visual information from the eye to the brain. In many cases, damage to the optic nerve is due to increased pressure in the eye, also known ...Read more

Can glaucoma be treated?

Can glaucoma be treated?

Yes: Observation, topical drops or other medications, laser, minimally invasive or conventional surgery: depending on side effects, stage of disease/current vision, health status, rate of progression, and eye pressure. ...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

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

What exactly is acute glaucoma?

Fluid block in eye: The eye has an internal clear fluid circulation 24/7. This is called the aqueous humor. The iris in certain shaped eyes (usually farsighted) can obstruct the outflow and within 1/2 hour the pressure can skyrocket to dangerous levels. This is an emergency, can be stopped with certain drugs and prevented with laser. See your ophthalmologist immediately if you suspect this condition. ...Read more

What are the stages of glaucoma?

Continuum: The glaucoma continuum has been proposed to describe the stages. Structure and function are mentioned. Early on, structural damage to the optic nerves occur without functional vision loss . As the disease progresses, visual deficits occur. ...Read more

What are the symptoms of glaucoma?

Depends: Most glaucoma is asymptomatic until end stage disease when the vision is decreased in both eyes. At that point, contrast, acuity, and peripheral vision are diminished. Thus, screening is key if at risk. A particular type called acute angle closure glaucoma with a sudden rise in eye pressure can have symptoms of red eye, severe eye pain, blurred vision, haloes, headache, nausea, vomiting... ...Read more
