Instead of using GAT for patients with astigmatism, consider using the Tono-Pen, a pneumotonometer or other devices if a patients cornea is significantly irregular (from refractive error, scarring, ectasia, etc.). High blood pressure results from the tightening of narrow arteries called arterioles. Lastly, look for signs of prior refractive surgery, as the cornea will be thinner than prior to surgery, and IOP readings may be artificially low.

Additionally, corneal thinning has been shown to result in underestimated IOP readingsa 25m reduction of CCT can lead to about a 1mm underestimation of pressure. The device calculates eye pressure by measuring the depth of the indentation on the cornea. Non-contact tonometry is sometimes called a "puff test." Clinicians need to develop a consistent, reproducible and reliable technique for obtaining IOP measurements so that they can be compared with confidence over time. IOP is often measured with applanation tonometry, where a small constant area of the clear cornea at the front of the eye is flattened and the force required to do so is converted into a pressure reading. American Academy of Ophthalmology. Apart from these, limiting alcohol consumption and avoiding smoking is the best way to control blood pressure.
