|20140163352||Portable Tonometer - An applanation tonometer uses an active pixel sensor array to accurately detect total illumination in a region surrounding an applanated area so that a microprocessor can determine the applanated area based on an inversion of the illumination received by the sensor.||06-12-2014|
|20110087086||Method of Estimating Ocular Perfusion Pressure - A microprocessor-controlled tonometer measures both systole and diastole occurring in intraocular pressure so that this information can be used to estimate perfusion pressure. The microprocessor determines a ratio between ocular pulse amplitude and mean intraocular pressure, derives a multiplier from the ratio, multiplies the mean intraocular pressure by the multiplier to estimate mean central retinal artery pressure, and then estimates perfusion pressure by subtracting mean intraocular pressure from the estimate of central retinal artery pressure.||04-14-2011|
|20090103047||Tonometer Using Camera and Ambient Light - A tonometer uses ambient light available in an eye examining room, rather than a dedicated source of light, to examine a characteristic of an eye. A digital camera in the tonometer views an image of the eye as it is engaged by a contactor that applanates or indents the cornea. An electromagnetic mount for the contactor can supply a force pressing the contactor against the eye. While the examiner observes the resulting image a strain gauge can also measure the deformation pressure applied to the eye by the contactor. A microprocessor can then determine a characteristic of the eye from signals supplied by the camera and the strain gauge or the electromagnet force applier.||04-23-2009|
