What is Eye Pressure? Why it is important to measure it? What are its normal readings?

Eye Pressure or Intraocular pressure (IOP) is the fluid pressure inside the eye. IOP is an important aspect in the evaluation of patients at risk from glaucoma. Eye pressure or IOP is measured in millimeters of mercury (mmHg).

Normal IOP readings range from 10 mmHg – 20 mm Hg. High IOP is the most important risk factor for Glaucoma.
