Doctor said my eye pressure is borderline, what does that mean?

Suspect glaucoma : Your eyes have a normal range of pressure that your eye doctor checks to screen for glaucoma. The 'normal' range is 10-21. Borderline means on the border, so your pressure may be 20-21. There are other things to check for glaucoma including optic nerve cupping and visual field testing. Make sure the docto checked your corneal thickness because that can effect the pressure measurement..

Eye pressure!: Most healthy eye have a pressure between 9-21. Your doctor is most likely refering to the pressure at the upper end of this or a point above (20-22). This is insignificant if the pressure does not affect or damage the optic nerve. There are many other things that need checked to determine if this pressure is significant and causing glaucoma.
