Normal-pressure glaucoma is diagnosed when the eye pressure is within the normal range of approximately 10 to 21 mm Hg but there is still evidence of the typical optic-nerve damage and vision loss seen in glaucoma. Many individuals diagnosed with normal-pressure glaucoma may actually have high pressures that are not found on routine examination, as eye pressure can vary quite a bit. Even individuals with untreated high-pressure glaucoma will have a normal pressure one-third of the time. The factors that might predispose you to normal-pressure glaucoma are not well understood, and your eye doctor may wish to do a medical work-up to ensure that you do not have another condition that might mimic glaucoma.
