23 - 25 is normal?

First of all, we should know what the normal intraocular pressure is. After big data analysis, normal people are not 100 percent in the normal range. The normal value of this range is 10-21mmHg. People within this range are an interval, and 95% of the intervals are within this range. There will also be some outside this range, such as below 10mmHg or above 21mmHg without disease, this is only 5% of that interval, this person belongs to high intraocular pressure, but there is no disease, it can not be called glaucoma. But more than 21mmHg high intraocular pressure, to determine whether he is glaucoma. Because there are quite a few people with high intraocular pressure, rather than glaucoma is a minority of people, more than 21mmHg above the vast majority of people should be a problem, that is, there will be glaucoma performance. If not treated in time, it will lead to optic nerve compression, optic nerve compression atrophy will show irreversible damage to vision. Therefore, once this happens, it is necessary to follow up closely and review regularly.
