Intraocular Pressure (IOP)


Intraocular pressure (IOP) refers to the fluid pressure inside the eye, which is essential for maintaining the eye's shape and proper functioning. It is a key parameter measured during eye examinations to assess eye health and detect conditions such as glaucoma. Normal IOP ranges from 12 to 22 mm Hg, with variations depending on factors like age, ethnicity, and time of day.
