A SYSTEM AND METHOD FOR PROVIDING VISUAL TESTS

Embodiments of the invention are directed towards systems, methods and computer program products for providing improved eye tests. Such tests improve upon current eye tests, such as visual field tests, by incorporating virtual reality, software mediated guidance to the patient or practitioner such that more accurate results of the eye tests are obtained. Furthermore, through the use of one or more trained machine learning or predictive analytic systems, multiple signals obtained from sensors of a testing apparatus are evaluated to ensure that the eye test results are less error-prone and provide a more consistent evaluation of a user's vision status. As it will be appreciated, such error reduction and user guidance systems represent technological improvements in eye tests and utilize non-routine and non-conventional approaches to the improvement and reliability of eye tests.

OPHTHALMIC APPARATUS
20230218167 · 2023-07-13 · ·

An ophthalmic apparatus includes an objective lens arranged to be passed through by first and second measurement optical axes that are positioned at a distance from each other. An OCT optical system performs OCT on a subject's left eye arranged on the first measurement optical axis or a subject's right eye arranged on the second measurement optical axis. An optical axis adjusting unit adjusts an optical axis of the OCT optical system under control of a controller so that the optical axis approximately coincides with any one of the first measurement optical axis and the second measurement optical axis. An intraocular parameter calculator calculates an intraocular parameter of the subject's left or right eye based on a detection result of interference light acquired in a state where the optical axis of the OCT optical system approximately coincides with the first or second measurement optical axis.

SYSTEM AND METHOD FOR MEASURING INTRAOCULAR PRESSURE AND OCULAR TISSUE BIOMECHANICAL PROPERTIES

Provided herein are systems and methods to measure the intraocular pressure, ocular tissue geometry and the biomechanical properties of an ocular tissue, such as an eye-globe or cornea, in one instrument. The system is an optical coherence tomography subsystem and an applanation tonometer subsystem housed as one instrument and interfaced with a computer for at least data processing and image display. The system utilizes an air-puff and a focused micro air-pulse to induce deformation and applanation and displacement in the ocular tissue. Pressure profiles of the air puff with applanation times are utilized to measure intraocular pressure. Temporal profiles of displacement and/or spatio-temporal profiles of a displacement-generated elastic wave are analyzed to calculate biomechanical properties.
