What is the normal range for intraocular pressure?

The normal range for intraocular pressure (IOP) is from 8 to 21 mm Hg. This range is established based on clinical observations and research that indicate pressures within this interval are generally considered healthy for the eyes. Elevated intraocular pressure can indicate the risk of glaucoma, a condition that can lead to vision loss if left untreated.

Values below 8 mm Hg may suggest conditions such as ocular hypotony, which can occur after surgery or as a result of eye disease, while pressures above 21 mm Hg may warrant further investigation to rule out glaucoma or other ocular issues. Understanding this normal range is critical for healthcare providers in assessing eye health and making informed decisions regarding patient care.
