Definition

Intraocular pressure (IOP) is the fluid pressure within the eye. It plays a crucial role in maintaining the shape of the eye and proper vision.

5 Must Know Facts For Your Next Test

  1. Intraocular pressure is typically measured in millimeters of mercury (mmHg).
  2. It is influenced by the balance between the production and drainage of aqueous humor, a clear fluid in the eye.
  3. Normal IOP ranges from 10 to 21 mmHg; deviations can indicate conditions like glaucoma.
  4. Changes in body posture, fluid intake, and certain medications can affect IOP levels.
  5. Fluid statics principles help explain how pressure variations within the eye can impact overall ocular health.
