A medical imaging binocular indirect ophthalmoscope with 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.

The present disclosure relates to a novel pupilometer and method of using the pupilometer to record and analyze direct and consensual reflex of pupils to identify brain lesion locations of a patient with brain injuries.

An apparatus for determining the refractive characteristics of an imaging system having an inaccessible and diffusive image surface, such as the human eye. Refractive characteristics of the entire wavefront are ascertained by measuring the refractive power of a representative sample of segments of the pupil. By illuminating only a selected segment, the characteristics of each individual segment may be accurately measured using illumination reflected by the diffusive image surface of the subject optical system, and transmitted only through the transmitting segment. Combination of the refractive characteristics of measured segments constitutes the pupil function of the measured optical system, and can be used for a precise determination of corrective lenses. Characteristics of the system measured, including spectral sensitivity and focusing, are also determined.

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.

System and method directed towards providing full and even illumination of a patient's retina through lighting integrated into a handheld fundus lens. By integrating the lighting, the method and system reduces and even eliminate many lens artifacts and reflections. By increasing the accuracy, quality, and field of view 10 afforded during clinical examination of the retina, the method and system will allow practitioners to make more accurate diagnoses and will increase safety during retinal surgical procedures.

An apparatus for parallel optical coherence tomographic funduscope includes an illumination arm, a processing unit, and a retina imaging interferometer. The illumination arm includes a light source used for emitting incident lights; the processing unit is used for processing raw images from the retina imaging interferometer to obtain fundus images; and the retina imaging interferometer which includes a sample arm, a reference arm, a detection arm and a blocking unit to block unwanted back reflections from optical elements and eye, is used for acquiring the raw images by a camera in the detection arm. The illumination and the reference arms are located in a first light path and the sample and the detection arms are located in a second light path. The blocking unit include a detection pupil located at the intersection of the first and second light paths to block unwanted back reflections from optical elements and eye.

Provided is an ophthalmologic apparatus, including: a scan unit configured to repeat two-dimensional scanning on a fundus of an eye to be inspected with measuring light; an image generation unit configured to generate a two-dimensional image of the fundus based on reflected light of the measuring light from the fundus that is two-dimensionally scanned; and a control unit configured to control, in the two-dimensional scanning, an amount of the measuring light that is radiated to the fundus and is not used to generate the two-dimensional image to be smaller than an amount of the measuring light that is radiated to the fundus and is used to generate the two-dimensional image.

A device is for imaging an eye and is wearable on the object to be examined or otherwise able to be placed to the front of an eye or eyes. When the device is switched on, it automatically performs the imaging such that all images are useful. The device comprises a camera arrangement with optics and a camera sensor, and an illumination arrangement. The device comprises a control arrangement that switches the camera arrangement to take automatically one or more images of the eye, when the device is in front of the eye. The device comprises an image analyzing arrangement or a connection to an image analyzing arrangement that is provided for detecting a reflection in the image taken by the camera arrangement or in the image area of the camera arrangement and for transmitting the information about the detected reflection to the control arrangement which is provided thereby to repeat or decline imaging. When repeating the imaging the control arrangement alters the parameters of imaging.

A scanning perimeter as disclosed herein comprises a first projection means projecting a first projection beam to uniformly illuminate a portion of a retina, said first projection beam passing through the pupil of the eye at a second separation region between a first crossing region, at which said illumination beam passes through the pupil, and a second crossing region of the pupil, at which light reflected by the retina passes through the pupil. A second projection means projects a second projection beam to project at least a fixation target on the retina, said second projection beam passing through the pupil at said first crossing region or said second crossing region. A third projection means projects a third projection beam to project at least a light stimulus on the retina, said third projection beam passing through the pupil at said first crossing region or said second crossing region.

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.
