What is the average intraocular pressure (IOP) reading that is considered of concern?

• A. 15mm Hg
• B. 20mm Hg
• C. 25mm Hg
• D. 30mm Hg

Answer: (C)

An average intraocular pressure (IOP) reading of 25 mm Hg is typically considered a point of concern in clinical practice. Normal IOP generally ranges from approximately 10 mm Hg to 21 mm Hg. Readings above this range can indicate potential problems such as glaucoma, especially when IOP exceeds 21 mm Hg.

An IOP of 25 mm Hg suggests that the pressure is elevated beyond what's typically considered normal, prompting further evaluation and possibly intervention to prevent optic nerve damage and preserve vision. Monitoring and managing elevated IOP is crucial in preventing conditions that lead to vision loss. This makes 25 mm Hg a significant threshold in ophthalmology as it flags the need for additional assessment and potential treatment options.
