Certified Paraoptometric (CPO) Practice Exam

Intraocular pressure (IOP) is a critical measurement in the assessment of eye health, particularly in the context of glaucoma and other ocular conditions. The typical normal range for intraocular pressure is 10 to 21 mmHg, which is widely accepted in the field of optometry and ophthalmology. This range represents the pressure inside the eye that is considered normal for the majority of individuals.

Maintaining intraocular pressure within this range is important for proper ocular function and preventing damage to the optic nerve. Values below 10 mmHg may suggest certain medical conditions, while pressures above 21 mmHg can indicate a risk for glaucoma or other eye diseases. The recognition of this normal range is essential for practitioners to detect anomalies and take appropriate clinical action.

The other ranges provided do not align with the established medical consensus on normal IOP levels, making them less accurate for assessing eye health. Understanding this normal range is critical in guiding patient care and monitoring for potential ocular conditions.
