Intraocular pressure (IOP) check is a part of a comprehensive eye examination that measures the pressure within the eye. The procedure is important in assessing the risk of developing glaucoma, a group of eye conditions that can damage the optic nerve and lead to vision loss. Elevated intraocular pressure is a significant risk factor for glaucoma, although it’s important to note that not all individuals with elevated IOP will develop glaucoma, and vice versa.

Regular measurement of intraocular pressure is important because elevated pressure can indicate an increased risk of glaucoma. However, it’s crucial to consider other factors such as the health of the optic nerve, visual field testing, and family history when assessing an individual’s overall risk for glaucoma.
