20100091242 | System and process for recording ERG, PERG and VEP multifocal electrofunctional responses in real-time - Process and system for determining the topography of bioelectric response signals of a visual system including a patient's retina, optical nerve or a projection thereof at the level of the central cortex, following visual stimulation through a surface arranged in front of the patient's eye. An image which comprises a plurality of cells is displayed as stimulation, each cell being activated or deactivated according to a corresponding digital time function represented by a cyclical succession of binary m-sequences of duration (T) formed from a plurality of activation symbols (N), each having a duration (Ts), the m-sequences of the various cells being obtained cyclically from a mother m-sequence. The process determines the total bioelectric response of the visual system, the response associated with each cell being determined by the total response of the visual system using a cross-correlation with a suitable translated version of a mother m-sequence. The calculation of the response of each cell is updated at the end of each symbol time (Ts), thereby making it possible to follow the evolution of the calculated response of each cell in real-time, without awaiting the end of an m-sequence. | 04-15-2010 |
20120033180 | OPHTHALMIC DEVICE AND METHOD - An ophthalmic device and method actively correcting possible movement of the eye of a patient with respect to the correct positioning during the examination are described. An illumination light beam is provided, that passes through a cross-section of the anterior chamber of the eye to capture an image on the corneal vertex. | 02-09-2012 |
20150294134 | METHOD AND APPARATUS FOR MEASURING ABERRATIONS OF A OCULAR OPTICAL SYSTEM - The present invention refers in general to the measurement of aberrations of the optical system (E) of a living being, in particular human. More specifically, the invention refers to methods and systems for reconstructing a wavefront (W(z,p)) and/or for constructing a refracting error map. | 10-15-2015 |
20160051137 | OPTICAL COHERENCE TOMOGRAPHY METHOD AND SYSTEM - The present invention relates to the field of instruments for imaging internal structures of the human body, and in particular of the eye. More specifically it relates to an optimized method and an optical coherence tomography system thereof. | 02-25-2016 |
