“What is normal eye pressure for glaucoma?”

There is no universal number that is normal pressure for everyone. It will depend on many other factors.Your eye doctor will be able to explain it to you in more details once you are examined. In most cases a pressure under 20 is considered to be normal. However it will depend on many other factors that doctor will learn about you during the examination.

Thank you for this great question. "Normal" eye pressure can be different from one person compared to another. And there are many different types of glaucoma. Your eye pressure is definitely one significant factor that may determine if someone has glaucoma or not. But there are other factors that must be considered and evaluated before someone is diagnosed with glaucoma. These include the corneal thickness, optic nerve findings including the cup to disc ratio, visual field testing, medications used including steroid use, health concerns including diabetes, age, refractive error, family history, race, and the anatomical angle evaluation which is a structure in your eye. There are some people who have higher than normal eye pressures without optic nerve damage or visual field losses who must be followed over time and are considered "glaucoma suspects". There are other people who have normal eye pressures that can have or develop glaucoma because their pressure may be too high for what their eyes can withstand.
Most "normal" eye pressures run between 10-20 mmHg, but again, please remember that this is only 1 factor, although very important.
I would suggest that you see an eye doctor to have your intraocular pressures checked, have a dilated exam in order to check your optic nerves, have a corneal thickness test called pachymetry, have a visual field test done in order to be sure that your visual fields are OK, and have your eyeglass prescription checked. I wish you good luck and best wishes.

There is no normal eye pressure for glaucoma you need to be followed by an optometrist or ophthalmologist. Everybody’s eye pressure is different and the amount of pressure lowering is different for each person. They need to calculate this for you based on what your eye pressure started out of hours and how much damage you already have.

Normal eye pressure is typically between 10-21mmHg. For glaucoma patients, your eye doctor will set a specific target pressure.

Normal eye pressure really varies from one person to another. If you have glaucoma we typically try to get a drop of about 20-30% from your highest recorded eye pressure reading. Typically, we like for patients pressure to be under 21, it means they are likely to have a decreased chance of developing glaucoma, but again that can be highly variable from person to person. The best thing to do is to regularly have a comprehensive eye exam to discus what pressure is best for your eyes and your situation.

Glaucoma is essentially systematic death of the optic nerve. Controlling/lowering eye pressure is one way to slow/stop the progression of the disease. For most people, eye pressure of 21mmHg and below is acceptable. With glaucoma, some people can still have progressive disease at much lower pressures, including single digits.

Usually under 20 mmHg
