Examples relate to a surgical microscope system, and to a system, a method and a computer program for a surgical microscope system. The system comprises one or more processors and one or more storage devices. The system is configured to obtain intraoperative sensor data of at least a portion of an eye from a Doppler-based imaging sensor of the surgical microscope system. The system is configured to process the intraoperative sensor data to determine information on a blood flow within the eye. The system is configured to generate a visualization of the blood flow. The system is configured to provide a display signal to a display device of the surgical microscope system based on the visualization of the blood flow within the eye.

Improved optical coherence tomography systems and methods to measure retinal data are presented. The systems may be compact, provide in-home monitoring, and have automation to allow the patient to measure himself or herself.

An ophthalmic portable laser slit lamp for ophthalmic examination and a method of eye inspection. The device comprises a portable housing containing an electronic timer circuit, a rechargeable battery, a laser module containing a laser emitting diode, a fixed focusing lens that sets the appropriate focal distance for the examination method and a line generator lens acting as a slit aperture. The laser beam aimed to the eye of the patient illuminates the eye with a very thin straight laser line at a fixed focal distance. The device also comprises a safety timer circuit that protects the patients eye against irradiation overload. The method of the invention allows the surgeon to detect surgical eye disorders at the operating room and helps to carry out a correct diagnosis in a much more precise and effective way than any light or laser spot device.

Systems and methods for vision test and uses thereof are disclosed. A method may be implemented on a mobile device having at least a processor, a camera and a display screen. The method may include capturing at least one image of a user using the camera of the mobile device; interactively guiding the user to a predetermined distance from the display screen of the mobile device based on the at least one image; presenting material on the display screen upon a determination that the user is at the predetermined distance from the display screen; and receiving input from the user in response to the material presented on the display screen. The material presented on the display screen may be for assessing at least one characteristic of the user's vision. Mobile devices and non-transitory machine-readable mediums having machine-executable instructions embodied thereon for assessing a user's vision also are disclosed.

An OCT imaging system may include an OCT light source operable to emit an OCT light beam, and a beam splitter operable to split the OCT light beam into a sample beam, transferred to a sample arm waveguide, and a reference beam, transferred to a reference arm waveguide. The sample arm waveguide and the reference arm waveguide may be coupled together within a cladding, wherein the cladding improves a calibration of a generated OCT image by fixing axial movement of the sample arm and reference arm waveguides relative to one another. By routing long reference and sample arm waveguide fibers together in the OCT system using a sheath/cladding, OCT image offset due to asymmetrical fiber stretching can be minimized or eliminated.

A medical system of an aspect example includes a data acquiring unit and a data processor. The data acquiring unit is configured to acquire data from an eye fundus of a patient using at least one optical method. The data processor is configured to process the data acquired by the data acquiring unit in order to generate information on the circulatory system of the patient.

An ophthalmic apparatus includes an objective lens arranged to be passed through by first and second measurement optical axes that are positioned at a distance from each other. An OCT optical system performs OCT on a subject's left eye arranged on the first measurement optical axis or a subject's right eye arranged on the second measurement optical axis. An optical axis adjusting unit adjusts an optical axis of the OCT optical system under control of a controller so that the optical axis approximately coincides with any one of the first measurement optical axis and the second measurement optical axis. An intraocular parameter calculator calculates an intraocular parameter of the subject's left or right eye based on a detection result of interference light acquired in a state where the optical axis of the OCT optical system approximately coincides with the first or second measurement optical axis.

An ophthalmic apparatus includes an objective lens, and an OCT optical system optical system is configured to project a measurement light onto a subject's left or right eye via an objective lens, and to detect interference light between returning light of the measurement light a reference light having traveled through a reference optical path. An optical axis switching member switches an optical axis of the OCT optical system to approximately coincide with a first or second measurement optical axis. A controller is configured to control the optical axis switching member. An intraocular parameter calculator calculates an intraocular parameter of the subject's left or right eye based on a detection result of the interference light acquired in a state where the optical axis of the OCT optical system is switched so that the optical axis of the OCT optical system approximately coincides with the first or second measurement optical axis.

There is provided a medical image processing apparatus including: an association processing section configured to associate multiple medical captured images in which an observation target is imaged by each of multiple imaging devices including imaging devices in which one or both of an in-focus position and an in-focus range are different; and a compositing processing section configured to depth-composite each of a medical captured image for a right eye and a medical captured image for a left eye among the multiple medical captured images by using an associated other medical captured image.
