Abstract
Proposed is a device and a method for determining the inner pressure of a human eye, in which a plurality of pressure sensing elements, placeable on the eye, are used for measurement, with spatial resolution, of pressure values, which pressure-sensing elements are preferably disposed in a pressure sensor array, in particular in a micro-electromechanical pressure sensor array with at least one line of pressure sensing elements. The intraocular pressure is determined from the sum of the measured sensor pressure values and the number of pressure-sensing elements contributing to the sum. Pressure distribution profiles with spatial resolution and pressure distribution matrices are able to be shown graphically.
Claims25
A device for determining intraocular pressure, comprising:
- a plurality of pressure-sensing elements;
- and
- processing means for determining the intraocular pressure from a sum of the sensor pressure values measured by the individual pressure-sensing elements and from a number of the pressure-sensing elements contributing to the sum.
A system for determining intraocular pressure, comprising:
- a measuring sensor for capturing measurement values for determining the intraocular pressure,
- comprising a plurality of pressure-sensing elements and an evaluation unit, comprising processing means for determining the intraocular pressure from the sum of the sensor pressure values measured by individual pressure-sensing elements and from the number of the pressure-sensing elements contributing to the sum;
- and
- an interface for transmission of the sensor pressure values, measured by the individual pressure-sensing elements, to the evaluation unit.
A method for determining intraocular pressure, comprising:
- at least one of placing directly and indirectly, a plurality of pressure-sensing elements on an eye;
- and
- determining the intraocular pressure from a sum of the sensor pressure values measured by the individual pressure-sensing elements from a number of the pressure-sensing elements contributing to the sum.
