A mobile communication device-based corneal topography system includes an illumination system, an imaging system, a topography processor, an image sensor, and a mobile communication device. The illumination system is configured to generate an illumination pattern reflected off a cornea of a subject. The imaging system is coupled to an image sensor to capture an image of the reflected illumination pattern. A topography processor is coupled to the image sensor to process the image of the reflected illumination pattern. The mobile communications device includes a display, the mobile communications device is operatively coupled to the image sensor. The mobile communications device includes a mobile communications device (MCD) processor. A housing at least partially encloses one or more of the illumination system, the imaging system, or the topography processor.

A fundus imager includes a handheld housing that supports a lighting unit configured to illuminate an eye fundus. The lighting unit includes one or more light-emitting diodes. The housing further supports a camera configured to capture one or more images of the eye fundus, and a display configured to display the one or more images of the eye fundus. The fundus imager captures at least one multispectral fundus image using the camera, and displays the at least one multispectral fundus image on the display.

A skin measuring microscope includes a housing, an electronic imager disposed along an imaging axis, and an illumination system. The illumination system includes a plurality of LEDs disposed in a ring-like configuration adjacent a distal end of the housing.

A medical diagnostic system can assess quality of a representation of a body part determined based on a response of the body part to exposure to electromagnetic waves, process the representation with a disease detection machine learning model to determine a certainty measure for a presence of a disease, determine a quality score for the representation based on the quality of the representation and the certainty measure, and discard the at least one representation based on the quality score. Combining machine learning in conjunction with one another, such as, for quality assessment and disease detection, can provide for more accurate image quality analysis, lead to faster medical imaging, and reduce the need to retake images or entirely re-perform medical imaging. The system can be easier to use, be more robust and faster than other systems by reducing the need to retake images while maintaining performance of the system.

Optical coherence tomography (OCT) imaging systems, handhold probes, and methods that use a field curvature to match a curved surface of tissue are disclosed. According to an aspect, an OCT imaging system includes optical elements to generate diverging light. The system also includes one or more mirrors and a lens system configured to scan the diverging light onto a curved surface of an object for imaging of the object.

A clinician eye camera apparatus, networked system, and medium to record eye images using the three different types of light to diagnose different medical conditions/disorders, comprising: 1) a camera unit housing a) a front PCB with a plurality of LED's and a middle aperture to fit a rear camera lens; b) a middle camera filter unit, comprising a plurality of light filters, and a servo motor with a propeller that rotates the light filters into position in front of a rear camera lens; c) the rear camera lens; and 2) a pivotable arm assembly comprising a top end unit attachable to the camera unit, and a middle handle unit pivotably attached to an arm unit. The arm assembly can be used in a straight handheld mode; or bent 90 degrees for mounting in a slit lamp. Images are transmitted to a clinician computer and/or a remoter server.

Disclosed herein are devices and methods for generating stereoscopic views of the eye (or any desired anatomic structure) using a dual-camera portable computing device. The locations of the two cameras are fixed, and the camera lenses may have different focal lengths. For example, the focal length of the second camera lens may be longer than the focal length of the first camera lens. One variation of a detachable imaging system comprises an objective lens and a relay lens that are disposed over the two cameras. The relay lens may be disposed over the first and second cameras, and have a focal length that is greater than the focal length of the first camera lens and less than or equal to the focal length of the second camera lens.

A contact arrangement for an eye examining instrument is located between an eye that is examined and a section of the eye examining instrument, the section is directed toward the eye that is examined. The contact arrangement is disposable, biocompatible with skin and made of biodegradable material. A first side of the contact arrangement is set in contact with the skin around the eye that is examined. A second side of the contact arrangement is attached with a counterpart of the eye examining instrument in a tool-free manner without touching with hands to the contact arrangement, the attachment being releasable, at the section, which is directed toward the eye that is examined.

A device for illuminating a posterior segment of an eye may include multiple channels. Each of the channels may include multiple illumination paths such as a first region illumination path, and a second region illumination path. The first region illumination path and the second region illumination path may be illuminated at different times such that a first region and a second region may be imaged without interference from a non-illuminated illumination path.

Disclosed are medical examination or diagnostic instruments and methods of operating such instruments. The method can include coupling an instrument head to a handle to form a medical examination or diagnostic instrument; detecting by the instrument head, a characteristic of the handle; and based at least in part on detecting the characteristic of the handle, determining, by the instrument head, a handle type associated with the handle, or detecting by the handle, a characteristic of the instrument head, and based at least in part on detecting the characteristic of the instrument head, an instrument head type associated with the instrument head. In some implementations, the emission of light can be controlled to be approximately linear in relation to a user input signal, as perceived by a user.
