Apparatus and methods are presented for spectral domain optical imaging, in particular for single shot 3-D spectral domain imaging of the retina of the human eye. In certain embodiments one or more 3-D images across elongated areas of an object are acquired, with scanning perpendicular to the long axis of the elongated areas for imaging extended volumes of the object. In preferred embodiments the captured light is sampled in the Fourier plane, in a dimension substantially perpendicular to the long axis, with a cylindrical lenslet array, while in other embodiments the captured light is sampled in the image plane. Apparatus and methods are also presented for hyperspectral imaging of the retina, with the illuminating beams preferably angled to suppress interference from corneal reflections. Apparatus and methods are also presented for multi-wavelength wavefront sensing, with simultaneous capture of light in two or more paths with different delays.

A retinal camera system comprises an eyepiece lens disposed within a housing, a retinal image sensor, and a visual guidance indicator. The retinal image sensor is adapted to acquire a retinal image of an eye through the eyepiece lens. The visual guidance indicator is disposed in or on the housing peripherally about the eyepiece lens. The visual guidance indicator is positioned and oriented relative to the eyepiece lens to emit a visual cue along an optical path that does not pass through the eyepiece lens. The visual cue is adapted to facilitate alignment of the eye to the eyepiece lens.

An optical headset comprises an outer frame that is wearable on the face of a user and an optics module that is removably mounted in the outer frame. The optics module can include a display visible to a wearer of the headset and a display visible to others while the headset is being worn. The outside display can be integral to the outer frame and driven via an electrical interface between the headset frame and the removable optics module. The removable optics module can include separate replacable subcomponents to allow for easy customization. Various components can be included in the optics module including a rotatable fundus camera.

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.

Provided is a wearable fundus camera configured to be worn as a headset by a human, the wearable fundus camera comprising: an infrared light source configured to output infrared light to be directed at a retina of the human; an image sensor configured to capture infrared images depicting a retina of an eye of the human under illumination from the infrared light source without a pupil of the eye being dilated with mydriatics; and an eye cuff configured to be biased against a face of the human and occlude at least some ambient light from reaching the image sensor.

Exemplary light control devices and methods provide a regional variation of visual information and sampling (“V-VIS”) of an ocular field of view that improves or stabilizes vision, ameliorates a visual symptom, reduces the rate of vision loss, or reduces the progression of an ophthalmic or neurologic condition, disease, injury or disorder. The V-VIS devices and methods generate a moving aperture effect anterior to a retina that samples and delivers to the retina environmental light from an ocular field of view at a sampling rate between 50 hertz and 50 kilohertz. Certain of these V-VIS devices and methods may be combined with augmented or virtual reality, vision measurement, vision monitoring, or other therapies including, but not limited to, pharmacological, gene, retinal replacement and stem cell therapies.

A medical device includes a head having a base and a piercing member fluidly connected to the base. The medical device includes a tube having a proximal end, a distal end, a first central channel extending from the proximal end to distal end, and a longitudinal axis extending substantially centrally through the first central channel, the distal end of the tube being removably attached to the base. The medical device includes a plunger slidably disposed partly within the first central channel of the tube, the plunger defining a second central channel, and the longitudinal axis extending substantially centrally through the second central channel. In some examples, the medical device includes an optic assembly having a light source and a light pipe that is disposed partly within the second central channel and being configured to receive radiation emitted by the light source; and direct the radiation through the piercing member.

A scleral depressor assembly includes a scleral depressor, an optical fiber, and a reflector. The scleral depressor includes an elongate body and a head disposed at a distal end of the elongate body. The scleral depressor defines an internal lumen extending through the elongate body and terminating within the head. The optical fiber is disposed within the lumen and includes a distal end positioned within the head. The optical fiber distal end includes a beveled end face that is obliquely oriented with respect to a central axis of the internal lumen. The reflector is disposed at the distal end of the optical fiber and is configured to reflect light emitted from the optical fiber distal end along a light path out of the scleral depressor head in a direction that is approximately orthogonal to the central axis of the internal lumen.

An ophthalmic system may comprise an imaging device having a field of view oriented toward the eye of the patient; a patient interface housing defining a passage therethrough, having a distal end coupled to one or more seals configured to be directly engaged with one or more surfaces of the eye of the patient, and wherein the proximal end is configured to be coupled to the patient workstation such that at least a portion of the field of view of the imaging device passes through the passage; and two or more registration fiducials coupled to the patient interface housing in a predetermined geometric configuration relative to the patient interface housing within the field of view of the imaging device such that they may be imaged by the imaging device in reference to predetermined geometric markers on the eye of the patient which may also be imaged by the imaging device.

A visual function test device 1 is provided with a housing 10 with a peephole; a visual target display 11 accommodated in the housing 10 to display a predetermined visual target; and virtual image optics accommodated in the housing 10, the virtual image optics being optics including lenses 121, 122 for forming a virtual image of the predetermined visual target at a position visible from the peephole, the virtual image optics having an exit pupil of a predetermined dimension. The visual function test device has an eye relief of 5 cm or more. By using the visual function test device 1, a visual function test can be performed without the need to mount equipment on a subject.
