Unfortunately, the answer is not any single number.
While the average eye pressure is approximately 15 mm Hg (millimeters of mercury), the range of normal eye pressure is much larger. About 90 percent of people will fall between a pressure of 10 and 21. Even so, this does not mean that if you have a pressure of 22 or higher it is abnormal. Every individual and every eye is different.There are many patients with pressures in the mid-20s who do not have glaucoma, and they can be followed with routine eye examinations by their eye care specialist. There are also patients who have been diagnosed with glaucoma and yet, even though treatment may decrease their pressure below 22, they still experience worsening of their glaucoma.
It is important that you see an eye care specialist to receive a thorough examination and determine if your eye pressure is problematic.
