Tonometry measures the pressure in the eye. 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.

The device is easily portable and is most advantageous when used on scarred or edematous corneas. 1963 Jul;2:274-83. Based on this concept, we present an instrumented measurement method, where multiple tactile stiffness sensors are used to infer the intraocular pressure of the eye. Visual motion sensitivity. Still, IOP should not be the only finding that determines a patients likelihood for progressive disease. You may undergo a tonometry test as part of a complete eye exam. Required fields are marked *. the wrist is the best place to check the pulse because the artery runs close to the skin and the bones create a firm place to feel the heart rate. no routine service or calibration checks are required. it is possible that there is no glaucoma at all, and it is just a tiny increase in eye pressure. 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.

The thickness and rigidity of the cornea can influence the measurement and this is taken into account by our eye doctor when they are examining the results. Magnesium may help relax blood vessels, making it easier for blood to pass through. Wang SY, Melles R, Lin, SC. The value that is measured is the amount of time it takes for the cornea to be flattened a specific amount, meaning that the longer it takes for the air puff to flatten the eye, the higher the internal pressure.
