Eye pressure is a known risk factor for the development of glaucoma. Commonly used eye pressure measuring devices, such as the Goldmann tonometer, utilize a technique that involves touching the eye. The pressure required for the tip of the Goldmann tonometer to flatten the cornea is recorded. However, it is known that some patients with apparently normal pressures recorded with this device still go on to develop glaucoma; others with high pressure readings never develop it. Pepose Vision Institute is one of the few centers in the U.S. chosen to evaluate the Ocular Response Analyzer (ORA), developed by Reichert Instruments, as a potentially more sensitive and accurate approach to measuring eye pressure. Not only does this Analyzer offer a potential breakthrough in detecting glaucoma in those patients with truly elevated eye pressure, but it can likewise save millions of dollars in pharmacy costs for patients that actually have normal eye pressure but have been measured improperly using current measurement techniques. Errors in measuring ocular pressure have been found to be related to corneal thickness, and will therefore be affected by laser vision correction procedures that change a patient’s corneal thickness. PVI is one of only a handful of eye centers in the country that has conducted clinical research related to this measurement issue. If you have had laser vision correction, or have naturally changing corneal thickness due to a chronic condition such as keratoconus, it is crucial that you select an eye care professional who is well-versed in differentiating between real increases in eye pressure and simple measurement error. Our cornea subspecialty-trained physicians have substantial experience in the diagnostics required to accurately measure true intraocular pressure for vision correction patients and others with corneal conditions, thereby enabling us to determine the optimal treatment to preserve and protect your vision.
