FYR accuracy rates within 5mmHg were: 47% for the first quarter of the sample; 100% for the second quarter; 80% for the third quarter and 100% for the last quarter.AP accuracy rates within 5mmHg were: 93% for the first quarter of the sample; 93% for the second quarter; 93% for the third quarter and 100% for the last quarter.Accuracy rates for the FYR were significantly improved after a training on 15 eyes (p=0.002). The normal eye pressure measurement ranges between 10-21 mm Hg. This balance of fluid production and drainage must be maintained to make sure the eye is constantly inflated and its structure is healthy. Checking Eye Pressure at Home: While many people are accustomed to measuring their own blood pressure with a home monitor, few if any glaucoma patients have measured their own eye pressure. Glaucoma is the gradual death of nerve fibers at the back of the eye that carry visual information from the eyes to the brain, resulting in a loss of peripheral vision and, if severe and left untreated, eventual complete loss of vision.

There are several types of applanating tonometers that range in how much of the cornea they push on and their respective accuracy. The size of the tonometer tip is deliberate to minimize the impact of the corneal resistance and the surface tension of the tear film.7 Two semicircles are visible through the bi-prism. Wang SY, Melles R, Lin, SC. A recent study from Germany sought to determine whether long-term treatment using these agents had a significant effect on CCT as measured by partial coherence interferometry.2 The researchers found that over a mean of 4.2 years, CCT decreased for those treated with PAs and combination therapies with PAs, CAIs and beta blockers. A strong pulse felt at the wrist correlates to a systolic blood pressure of at least 80 mmHg. Data shows checking blood pressure using fingers may not be accurate though there is an obscure method to correlate the pulse reading with systolic (upper) blood pressure.
