Improved optical coherence tomography systems and methods to measure thickness of the retina are presented. The systems may be compact, handheld, provide in-home monitoring, allow the patient to measure himself or herself, and be robust enough to be dropped while still measuring the retina reliably.

Stereoscopic display systems and methods for displaying surgical data and information in a surgical microscope are disclosed herein. According to an aspect, a system includes first and second eyepieces. The system includes a display having first and second display portions, configured to display first images in the first display portion, and configured to display second images in the second display portion. The first image and the second image are projected along a first pathway and a second pathway. The system includes a first optical element positioned to relay the first images into the first eyepiece. The system includes a second optical element positioned to relay the second images into the second eyepiece.

The present disclosure relates to a medical microscope field. A stereo microscope connected to an optical coherence tomography (OCT) unit for forming a tomographic image of a target object includes an objective lens unit including a plurality of lenses each having an aperture of a predetermined size, a pair of first magnification lens units each including a plurality of lenses having a pair of magnification lens apertures positioned within the aperture of the objective lens unit, a second magnification lens unit including a plurality of lenses having an OCT aperture disposed separately from the pair of magnification lens aperture within the aperture of the objective lens unit, and a light delivery unit configured to receive light from the OCT unit and deliver the light to the second magnification lens unit and configured to deliver light received from the second magnification lens unit to the OCT unit.

A surgical microscope for generating an image of an object region includes an eyepiece and an objective conjointly defining a viewing beam path, an image capturing device and a beam path switching device for out-coupling image information. The switching device is switchable between a first switching state wherein light in the viewing beam path is split into a first component along a first beam path to the eyepiece at an intensity IT1 and a second component along a second beam path to the image capturing device at an intensity IT2 and a second switching state wherein the light in the viewing beam path is deflected into the second beam path to the image capturing device at an intensity IU. The switching device includes a beam splitter movable in and out of the viewing beam path and a deflecting element movable into and out of the viewing beam path.

The object of the present invention is to develop an ophthalmologic microscope of a new method that increases the degree of freedom in the optical design in the Galilean ophthalmologic microscope provided with an OCT optical system. The present invention provides an ophthalmologic microscope 1 comprising; an illuminating optical system 300, an observation optical system 400; an objective lens 2; and an OCT optical system 500, characterized in that the optical axis O-500 of the OCT optical system does not penetrate through the objective lens 2, it comprises objective lens for OCT 507 through which the optical axis O-500 of the OCT optical system penetrates, and deflection optical elements 503a, 503b for scanning of the OCT optical system and the objective lens for OCT 507 are in a substantially optically conjugate positional relation.

The present invention is directed to a medical imaging binocular indirect ophthalmoscope with onboard sensor array and computational processing unit, enabling simultaneous or time-delayed viewing and collaborative review of photographs or videos from an eye examination. The invention also claims a method for photographing and integrating information associated with the images, videos, or other data generated from the eye examination.

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.

This present invention comprises a Galilean tele-microscope lens assembly configured to attach to the front of a binocular indirect ophthalmoscope (BIO) either permanently or by means of a clip or other suitable detachable mechanism, and to enhance an image of a patient's ocular fundus produced by a condensing lens hand-held by the examiner, at their arm's length, in front of the patient's eye. The lens assembly of the present invention magnifies the examiner's view of the hand-held condensing lens itself, and thus magnifies the fundus image produced by the hand-held condensing lens, enabling improved appreciation of finer details in an examination. In addition to improving BIO examinations in general, the present invention is especially advantageous for patients who have disabilities, are wheelchair bound, are children, or are patients of “mission” based ophthalmoscopy services provided in developing, “emerging economy” countries where other examination equipment may not be available.

Improved optical coherence tomography systems and methods to measure thickness of the retina are presented. The systems may be compact, handheld, provide in-home monitoring, allow the patient to measure himself or herself, and be robust enough to be dropped while still measuring the retina reliably.

A device is provided that may include an illuminator operable to interrogate at least a lens of an eye. The illuminator may include at least one light source and a lens positioned with respect to the light source to produce interrogating radiation. The device also may include a detector operable to image the total autofluorescence response of the lens of the eye as viewable through a pupil of the eye, the detector comprising an image sensor. The device can also include a controller operable to control operation of the illuminator and the detector. The controller may interrogate at least the lens of the eye by activating the illuminator for a select time, obtain at least one image of the total autofluorescence response of the lens at the detector during or immediately subsequent to the select time, and transmit the at least one image to a remote device.
