Patent number: 9028065Abstract: A ophthalmologic method and apparatus for processing a captured image of a tear film lipid layer on a cornea of a patient's eye to be examined and for classifying types of dry eye of the patient's eye. The captured image of the tear film lipid layer is processed to measure a movement speed of the tear film lipid layer at the time of opening of the patient's eyelid. The captured image of the tear film lipid layer is further processed to measure a time until the tear film lipid layer is broken up after the patient's eyelid has been opened and a break up region is detected. The type of dry eye of the patient's eye is classified based on the two measurement results.Type: GrantFiled: January 21, 2011Date of Patent: May 12, 2015Assignees: Kowa Company, Ltd., Kyoto Prefetural Public University CorporationInventors: Norihiko Yokoi, Yutaka Mizukusa, Shigeru Kinoshita

Patent number: 8950068Abstract: A mountable device includes a bio-compatible structure embedded in a polymer that defines at least one mounting surface. The bio-compatible structure has a first side defined by a first layer of bio-compatible material, a second side defined by a second layer of bio-compatible material, an electronic component, and a conductive pattern that defines sensor electrodes. A portion of the second layer of bio-compatible material is removed by etching to create at least one opening in the second side in which the sensor electrodes are exposed. The etching further removes a portion of the first layer of bio-compatible material so as to create at least one opening in the first side that is connected to the at least opening in the second side. With this arrangement of openings, analytes can reach the sensor electrodes from either the first side or the second side of the bio-compatible structure.Type: GrantFiled: September 20, 2013Date of Patent: February 10, 2015Assignee: Google Inc.Inventor: James Etzkorn

Patent number: 8926809Abstract: An eye-mountable device includes an electrochemical sensor embedded in a polymeric material configured for mounting to a surface of an eye. The electrochemical sensor applies a stabilization voltage between a working electrode and a reference electrode to allow the amperometric current to stabilize before powering measurement electronics configured to measure the amperometric current and communicate the measured amperometric current. The electrochemical sensor consumes less power while applying the stabilization voltage than during the measurement. The measurement is initiated in response to receiving a measurement signal at an antenna in the eye-mountable device.Type: GrantFiled: September 20, 2013Date of Patent: January 6, 2015Assignee: Google Inc.Inventors: Nathan Pletcher, Brian Otis

Patent number: 8332007Abstract: Methods and apparatus are disclosed for measuring and mapping oxygen tension in a tissue and, in particular, permit direct non-invasive measurement of retinal tissue oxygen tension. In one aspect, the invention is directed to methods for determining oxygen tension in a target tissue sensitized with an oxygen sensitive probe by imaging the target tissue. In one embodiment, the invention provides a noninvasive method for monitoring oxygen tension in a chorioretinal tissue sensitized with an oxygen sensitive probe. In another aspect, apparatus is disclosed that can determine oxygen tension in tissue by quantifying a signal emitted by an oxygen sensitive probe within the three-dimensional map of a tissue to determine oxygen tension and provide a three-dimensional map of oxygen tension variations.Type: GrantFiled: January 12, 2010Date of Patent: December 11, 2012Assignee: The Board of Trustees of the University of IllinoisInventor: Mahnaz Shahidi
