Eye Pressure Differences

Question:

When the eye pressure is checked. Should the readings be the same in both eyes?  If not, how far apart can they be before it is an issue of concern, or before it should be rechecked for accuracy? Is a difference of 1- 2 acceptable? How about greater than 2? What is the significance if it’s greater than 2.

A difference of two or three mm of mercury does not even raise my eyebrows.  That is quite common.  A difference of 5 or greater is suspicious.  Hope that helps, Rick Cohn, MD

My experience in 31 years of glaucoma treatments I have never ever had the same pressure in each eye. The only time it was reported to be the same and higher than my normal readings, I was suspicious and got another check from my regular Opth. and they were normal (for me) again. PS we’re lucky here to have Dr. Rick’s advice. Bill

Response:

The pressure in my left eye is always higher than in the right one. The difference is variable (from 3  to 6 mm). Thanks to Xalatan the pressure remains under 19 mm. My ophtalmologist tells me that the glaucoma in my right eye is an open angle one but he is less positive for the left eye. Is it possible to suffer from an open angle glaucoma in one eye and a closed angle one in the other ?
