How many people have normal-tension glaucoma?

In the United States, roughly half of all glaucoma patients have normal-tension glaucoma, with eye pressures below 22, according to the Baltimore Eye Study.

What does normal-tension glaucoma mean?

Normal-tension glaucoma (NTG), also known as low tension or normal pressure glaucoma, is a form of glaucoma in which damage occurs to the optic nerve without eye pressure exceeding the normal range. In general, a “normal” pressure range is between 12-22 mm Hg.

Is glaucoma normal-tension glaucoma?

Normal tension glaucoma (NTG) is a common form of primary open angle glaucoma (POAG) in which there is no measured elevation of the intraocular pressure (IOP). The clinical characteristics of NTG have many similarities to those in POAG, with a few notable distinctions.

How fast does normal-tension glaucoma progress?

Risk factors Women were found to progress more rapidly. Age was not a factor for progression, Dr. Anderson said. “Only half of the patients who present with normal-tension glaucoma will progress over a period of 5 to 7 years.

Is normal tension glaucoma curable?

Treatment. Although glaucoma’s damage can’t be reversed, your doctor will try stop it from getting worse and slow or prevent more vision loss. They may prescribe eye drops, or refer you to an ophthalmologist who specializes in glaucoma for laser treatment, or to talk with you about surgery.

Does low pressure glaucoma lead to blindness?

If left untreated, glaucoma will eventually cause blindness. Even with treatment, about 15 percent of people with glaucoma become blind in at least one eye within 20 years.

Is normal tension glaucoma common?

On average, these studies show that normal tension glaucoma (NTG) occurs in roughly 30 to 40% of all patients diagnosed with a glaucomatous visual field defect.

What are the causes of normal tension glaucoma?

Chronic low vascular perfusion, Raynaud’s phenomenon, migraine, nocturnal systemic hypotension and over-treated systemic hypertension are the main causes of normal tension glaucoma.

How can eye drops help with normal-tension glaucoma?

Eye drops used in managing glaucoma decrease eye pressure by helping the eye’s fluid to drain better and/or decreasing the amount of fluid made by the eye. Drugs to treat glaucoma are classified by their active ingredient. These include: prostaglandin analogs, beta blockers, alpha agonists, carbonic anhydrase inhibitors, and rho kinase inhibitors. In addition, combination drugs are available for patients who require more than one type of medication.

What are the main causes of glaucoma?

The cause of glaucoma from a scientific point is increased fluid pressure within the eye that causes a disruption in normal function.

In case of glaucoma with nasal step visual field defect, the focal thinning of RNFL at temporal upper or temporal lower areas can suggest an unique pattern of glaucoma . In cases with diffue thinning of RNFL or half (upper or lower), the differential characteristic can be glaucoma or non-glaucomatous optic neuropathy
