A1.2 to 2.4 mm Hg
B120 to 240 mm Hg
C12.0 to 24.0 mm Hg
D60.0 to 90.0 mm Hg
Answer & Solution
Correct answer: C. 12.0 to 24.0 mm Hg
1. The shape of the eye is held by a fluid pressure known as intraocular pressure.
2. Its normal range is 12.0 to 24.0 mm Hg.
3. A blockage in the circulation of that fluid can push it as high as 85.0 mm Hg, a condition called glaucoma.
4. The range 60.0 to 90.0 mm Hg is the resting diastolic blood pressure in large arteries, not an eye pressure.
5. The other two ranges are the correct figures shifted by a factor of ten in either direction.
