Question: What’s a normal eye pressure?

Answer: Normal eye pressure is usually considered 10 to 21 mmHg.

Despite this being the “normal” range, there are many people with pressures of 22-28 that we describe as ocular hypertension who don’t seem to manifest any glaucoma damage. Also, there are many people with pressures under 21 who develop glaucoma.

Thus, you have to look at the “big picture” when determining if an eye pressure is “normal.”

Obviously it’s easy to say “sorry i think normal eye pressure is 18 to 26 mmhg. thanks” or “Nope, it’s 10 - 21 as stated here.”… but where is your data to back up what your stating? Without some hard evidence to back up what either have stated is fracken bull$hit from both parties and helps no one! I will search it out and get back here in a few weeks with some viable answers to this important question, some of us need to know and are looking for an honest answer.

My eye pressure is 18 in both eyes and I am being treated for glaucoma. The doctor just raised the number of drops to five a day of two medications. My husband is very concerned and wants to rush me off to Mayo or the eye clinic in Salt Lake City. How concerned should I be about all of this?
