Provided herein is a corneal topography system that utilizes a prism placed in optical alignment between the pattern image generator, such as a Placido disk, and the eye. The corneal topography system may be a prismatic triangulating corneal topography system that utilizes light rays of angle θ at the edge of the prism not passing through the prism, light rays that deviate from angle θ passing through the prism and light rays of angle a calculated from the reflection image to determine the corneal reflection point on the corneal surface. Also provided is a method for mapping a corneal surface of an eye of a subject utilizing an optical prism to produce a reflection image from a corneal surface reflection point on the corneal surface of the eye.

An apparatus includes: a memory storing one or more instructions; and a processor configured to execute the one or more instructions to: obtain a plurality of images, each of the plurality of images including an eye of a subject; obtain a plurality of gaze angles, each of the plurality of gaze angles corresponding to the eye of the user; and detect liveness of the subject based on the plurality of gaze angles.

An immersive display system for eye therapies includes an ophthalmic microscope and: a double video camera, connected to a local network infrastructure; the double video camera oriented for filming the surgery operation; at least one computerized control unit, connected to the local network infrastructure, receiving images from the double video camera and processing them in a three-dimensional digital format; and at least one computerized controller, receiving the images processed by the computerized control unit. Also included is at least one helmet adapted to be worn on the head by the surgeon during the surgery operation, the helmet provided with a viewer arranged before the wearer's eyes, configured for three-dimensional image display, providing virtual reality content; the viewer allows the surgeon exclusive viewing of the three-dimensional images processed by the computerized control unit; the helmet being connected to the local network infrastructure to allow image reproduction in real time.

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.

A wide-field fundus indirect ophthalmoscopy method and apparatus are provided that can be miniaturized to be suitable for employment in a smartphone and that overcome limitations of existing smartphone wide field fundus imaging devices and methods, such as high cost, clinical deployment challenges and limited field of view. The wide-field fundus indirect ophthalmoscopy method and apparatus are also well suited for use in rural and underserved areas where both expensive instruments and skilled operators are typically not available. The wide-field fundus indirect ophthalmoscopy method and apparatus enable wide-field snapshot fundus images to be captured with wide fields of view (FOV) under mydriatic and non-mydriatic conditions and also enables video recordings of the fundus to be captured from which montages can be constructed with even wider FOVs.

An eye imaging device including a housing with an opening that can be in contact with a head of an observer, a first photographic optical system arranged in the housing and configured to image a left eyeball of the observer from a side, a second photographic optical system arranged in the housing opposite to the first photographic optical system and configured to image a right eyeball of the observer from a side, a third photographic optical system arranged slidable in the housing in a direction in which the first photographic optical system and the second photographic optical system face each other and configured to image the left eyeball and the right eyeball of the observer from a front, and a storage unit configured to store images captured by the first photographic optical system, the second photographic optical system, and the third photographic optical system is provided.

An independent wearable biomedical imaging system for early tumor detection the system including a physician headset having a graphical display in wireless communication with a patient headset having a left and right camera. The physician headset includes a map template database disposed in the memory storage drive including data specifying anatomical location of a patient tumor using sclera scans of a patient sclera and iris received from the patient headset. The physician can visually access the sclera scans from the patient headset camera and overlay with the map template to compare patient scan biomarkers with the map data. The physician may use the results in indicating strong genotype predisposition to tumors and tumor formation. The system algorithm would continue to amass biodata in the datasets helping the physician to increase accuracy in generating eye reports and statistical probability of tumor as well as genetic marker predisposition of the same.

A method implemented on a computing device having at least one processor, storage, and a communication platform connected to a network may include: obtaining a head image of a user with one or more dimension indicators, determining an eye region in the head image of the user and determining a pupillary distance of the user based on the one or more dimension indicators and the determined eye region. A method implemented on a computing device having at least one processor, storage, and a communication platform connected to a network may include: receiving a request at a user terminal, recording a video of a user wearing a wearable device with the user terminal, determining a pupillary distance of the user based on the video and synchronously displaying the pupillary distance on the video of the user during recording. The wearable device may include one or more dimension indicators.

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.

An optometry system for examining a subject eye of an examinee includes an optometry device for examining the subject eye, an imaging unit that captures an image of an examination room including the examinee and the optometry device, and a remote operation unit that includes a display unit which displays an operation screen for operating the optometry device and an captured image captured by the imaging unit, and a display control unit which controls display of the display unit to display the operation screen and the captured image on the display unit. The remote operation unit enables an examiner to observe the captured image displayed on the display unit to guide the examinee to an examination position.
