What are high numbers for glaucoma?
According to the Glaucoma Research Foundation, the range for normal pressure is 12 – 22 mm Hg. When the pressure exceeds 22 mm Hg, that usually indicates an abnormal glaucoma test. People with pressure around 16 mm Hg or higher may also be at risk for normal tension glaucoma.
Can a person with high eye pressure get glaucoma?
Historically, glaucoma was identified as a disease in which the eye was firm or hard due to high eye pressure. However, doctors gradually came to understand that glaucoma can occur even when eye pressure is normal, which sometimes makes it harder to diagnose.
When to lower eye pressure with glaucoma?
In that case, despite the initial eye pressure lowering, your ophthalmologist may determine that this new lower eye pressure is still “too high” and your eyes need to have even lower eye pressures.
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 …
Can a person go blind with high eye pressure?
I’ve heard that glaucoma is caused by high eye pressure, and that left untreated glaucoma can cause blindness. At what pressure will I go blind? Glaucoma is a multi-factorial, complex eye disease with specific characteristics such as optic nerve damage and visual field loss.
Historically, glaucoma was identified as a disease in which the eye was firm or hard due to high eye pressure. However, doctors gradually came to understand that glaucoma can occur even when eye pressure is normal, which sometimes makes it harder to diagnose.
What is the normal pressure range 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 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.
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
