What is considered normal intraocular pressure?

• A. 2-5 mm Hg
• B. 5-10 mm Hg
• C. 10-23 mm Hg
• D. 25-40 mm Hg

Answer: (C)

Normal intraocular pressure (IOP) is typically defined as ranging from 10 to 21 mm Hg, with values of 10-23 mm Hg being considered acceptable in many clinical contexts. This pressure is vital for maintaining the shape of the eye, ensuring proper optical function, and is regulated by the production and drainage of aqueous humor. The levels of IOP are important in monitoring for conditions such as glaucoma, where elevated pressure can lead to optic nerve damage. Values consistently above this range may indicate potential risks for glaucomatous changes, while values below this range can reflect various ocular conditions or insufficient aqueous humor production. Understanding this range is crucial for effective screening and diagnosis within ophthalmic practice.
