Disclosed herein are methods and apparatus for making a determination about an eye in ambient lighting conditions comprising detecting ambient light reflected out of an eye of a subject from a retina of the eye of the subject and making a determination about the eye of the subject based upon the reflected ambient light.

An ophthalmic device for imaging an eye, wherein a scanning element scans a first portion of light beam across a region of an eye via a light guiding component and a second portion of the light beam is reflected back by the light guiding component. The ophthalmic device further comprises: a light detector to detect light reflected from eye and guided to the light detector by the light guiding component; and a dynamic amplitude mask which receives the light reflected from the eye and the light reflected back by the light guiding component, and has an unmasked portion to allow light reflected from the eye to reach the light detector, and a masked portion whose spatial distribution varies with a scan angle such that the masked portion prevents light reflected back by the light guiding component from reaching the light detector during the scan.

An imaging system for generating an image of a region of an eye, comprising: an ocular imaging device controlled by a control module to acquire, from a first viewpoint, a first ocular image of the region having an image artefact caused by obstruction from imaging of a part of the region by an object, and a second ocular image from a predetermined second viewpoint, which shows at least a portion of the part of the region that was obstructed from imaging during acquisition of the first ocular image; and an image data processing module for combining the first and second ocular images to generate an enhanced ocular image having an image artefact caused by obstruction from imaging by the object which is smaller in relation to the image artefact in the first or second ocular image, or no such image artefact.

Disclosed is a coaxial non-mydriatic multispectral fundus camera, including: an illumination unit configured to emit light; a diffusion lens configured to diffuse the light incident from the illumination unit; an illumination lens configured to irradiate the light incident from the diffusion lens at a predetermined emission angle; a mirror configured to reflect the light incident from the illumination lens; a polarizing beam splitter configured to transmit P-polarized light of the light incident from the mirror and reflect S-polarized light thereof; an objective lens configured to image a fundus using the light incident from the polarizing beam splitter and then enlarge a returning image of the fundus; a short-range eyepiece lens configured to reduce or enlarge the image of the fundus enlarged by the objective lens; and an imaging device configured to acquire a fundus photograph from the image of the fundus received from the short-range eyepiece lens.

An eye-examining apparatus in which a visible light optical system for observing a shape of an examinee's eye and an infrared optical system for detecting a shape of the cornea of the examinee's eye are integrated. The eye-examining apparatus having an integrated optical system comprises: an infrared light source for irradiating a cornea of the examinee's eye with infrared light; a visible light source for irradiating the eye with visible light; an image detector both for detecting an image of the infrared light which is irradiated from the infrared light source and reflected from the cornea of the eye and for detecting an image of the visible light which is irradiated from the visible light source to the eye; and a visible light blocking filter inserted in an optical path of the visible light and the infrared light traveling toward the image detector for blocking the visible light.

Disclosed is a polarization fundus camera including: an illumination unit emitting light; a diffusion lens; an illumination lens irradiating the light introduced from the diffusion lens; a mirror reflecting light introduced from the illumination lens; a polarization beam splitter; an objective lens enlarging an image of a fundus formed by the light introduced from the polarization beam splitter; a short-range eyepiece lens reducing an image of the fundus enlarged by the objective lens; a linear polarization filter; a narrowband optical filter; and an imaging device.

There is provided an information processing apparatus to make it possible to dynamically change the blinking pattern of the light source according to the imaging result, the information processing apparatus including: a light source control unit configured to control each of light sources constituting a plurality of light sources that irradiate an eye with light; and an image acquisition unit configured to acquire a captured image of the eye including a bright spot that is a reflection point of the light. The light source control unit controls blinking of each of the light sources on a basis of the captured image of the eye.

A method of automating the collection, association, and coordination of multiple medical data sources using a coordinating service application, computer, database, and/or server system to manage devices, examinations, and people involved in the medical examination and treatment process. In an embodiment, the method comprises authenticating a user for a premises, a device, or a device group, validating particular use of the device based on user credentials or type of device or device group, associating a medical examination with a patient or a medical examination schedule, associating medical examination data from a device or device group with a related medical examination session, routing medical examination data to a computer, database, or server, and pairing medical examination session data with a medical interpretation, clinical testing results, diagnoses, and/or other recorded information.

A device for exploring the visual system, comprising portable viewing equipment having at least one viewing screen configured to be placed facing at least one eye of a person. The viewing equipment comprises sealing lips surrounding the viewing screens and having a free edge intended to be applied against the skin of the person, this free edge comprising at least one electrode for measuring the electrical potential. The device also comprises at least one free electrode for measuring the electrical potential, which free electrode is linked by a connecting wire to a connector carried by the viewing equipment, between one of the viewing screens and the free edge of the sealing lips surrounding this screen.

The present disclosure relates to sensor systems for electronic ophthalmic devices. In certain embodiments, the sensor systems may comprise a selection layer configured to reject light from the eye within a first range of incident angles and allow light from the eye within a second range of incident angles to pass through the selection layer. The sensor system may comprise a plurality of photodiodes disposed below the selection layer and configured to detect the light from the eye within the second range of incident angles that is allowed to pass through the selection layer. The sensor system may comprise an output circuit electrically coupled to the plurality of photodiodes and configured to output a signal indicative of which photodiode of the plurality of photodiodes detected the light.
