Question

What is the normal IOP reading for a tonometer?

1) 10-21 mm
2) 22-30 mm
3) 5-9 mm
4) 31-40 mm

Answer 1

The normal IOP reading for a tonometer is between 12-24 mm Hg.

Step-by-step explanation:

The normal IOP (intraocular pressure) reading for a tonometer is between 12-24 mm Hg (millimeters of mercury).

A tonometer is used to measure the fluid pressure inside the eye, which is important for detecting conditions like glaucoma.

Pressures outside this range may indicate abnormal eye conditions that require further examination by an eye specialist.
