What is considered high pressure for glaucoma?
Some eye doctors treat all elevated intraocular pressures of higher than 21 mm Hg with topical medicines. Some do not medically treat unless there is evidence of optic nerve damage. Most eye doctors treat if pressures are consistently higher than 28-30 mm Hg because of the high risk of optic nerve damage.
What are normal eye pressures for glaucoma?
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.
How is glaucoma related to high eye pressure?
A: Glaucoma is an eye condition whereby the optic nerve fibers die from a lack of blood supply (nutrition). This used to be associated only with high eye pressure. We now know that it is the blood flow to the optic nerve, which connects the back of the eye to the brain, that makes a difference in glaucoma — not just eye pressure.
How is normal tension glaucoma treated in patients?
Patients who have normal-tension glaucoma are thought to have more susceptible optic nerves, such that even at normal eye pressures the optic nerve slowly degenerates. Moreover, even though the eye pressure is “normal,” the treatment is the same: lowering the eye pressure through medications, laser, or surgery.
Is it normal to have high eye pressure?
These daily changes are normal. Usually, the higher the pressure, the more risk to the optic nerve. Some optic nerves develop glaucoma even at low pressures (this is called normal-tension glaucoma) so it is important to have the optic nerve examined no matter what the pressure may be.

Can a person with normal IOP develop glaucoma?
While increased pressure inside the eye (called intraocular pressure or IOP) is usually present, even patients with normal range IOP can develop glaucoma. There is no specific level of elevated eye pressure that definitely leads to glaucoma; conversely, there is no lower level of IOP that will absolutely eliminate a person’s risk …
What is the normal eye pressure for glaucoma?
That is why early diagnosis and treatment of glaucoma is the key to preventing vision loss. Eye pressure is measured in millimeters of mercury (mm Hg). Normal eye pressure ranges from 12-22 mm Hg, and eye pressure of greater than 22 mm Hg is considered higher than normal.
Patients who have normal-tension glaucoma are thought to have more susceptible optic nerves, such that even at normal eye pressures the optic nerve slowly degenerates. Moreover, even though the eye pressure is “normal,” the treatment is the same: lowering the eye pressure through medications, laser, or surgery.
Can you have ocular hypertension if you have glaucoma?
If your eye pressure, also called intraocular pressure or IOP, registers higher than that range, it doesn’t automatically mean that you have glaucoma. If your eye doctor doesn’t see evidence of glaucoma, the condition is labeled ocular hypertension. This can exist on its own, or eventually lead to glaucoma.
While increased pressure inside the eye (called intraocular pressure or IOP) is usually present, even patients with normal range IOP can develop glaucoma. There is no specific level of elevated eye pressure that definitely leads to glaucoma; conversely, there is no lower level of IOP that will absolutely eliminate a person’s risk
