    摘要: A device for detecting motion of a surface includes a light source for emitting light, a focusing lens configured to focus the light, and a detector configured to receive the focused light reflected off the surface and to detect motion of a distribution pattern of the reflected light. The motion of the distribution pattern of the reflected light is indicative of the motion of the surface. A conic constant of the focusing lens is in the range from □1.5 to □0.5, and a diameter of the focusing lens is at least 60% of the distance from the focusing lens to a beam waist of the focused light. When the conic constant and the diameter are within the above-mentioned ranges, the device is suitable for handheld apparatuses for free-hand measurements of small motions of surfaces. A handheld apparatus can be for example an apparatus for detecting eye pressure.

    摘要: In one aspect, the present disclosure relates to an eyewear-based system and method comprised of an ocular compression device positioned around a user's head to compress the globes of a user's eyes using direct mechanical force to artificially elevate the user's intraocular pressure. An application of this system is to increase intraocular pressure in users with glaucoma or users who are at risk for glaucoma to assess novel biomarkers for glaucoma progression. The ocular compression device may be used in conjunction with an ocular imaging device, such as an optical coherence tomography angiography device, to characterize changes in the user's optic nerve head structure as a function of intraocular pressure. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

    摘要: Assemblies and methods for modifying an intraocular pressure of a patient's one or both eyes are disclosed. The assemblies and methods can be used to treat, inhibit, or prevent ocular conditions such as glaucoma, high intraocular pressure, optic disc edema, idiopathic intracranial hypertension, zero-gravity induced papilledema, and other optic pressure related conditions. An assembly can include a goggle including at least one cavity, a pump in fluid communication with the at least one cavity, and a control mechanism. The control mechanism can be operatively coupled to the pump and can maintain a target pressure or target pressure range in the at least one cavity, which, when the assembly is worn by a patient, is the area between a patient's eye(s) and wall surfaces of the goggle. Controlling the pressure over the outer surfaces of the patient's eye(s) can drive a desired change in the intraocular pressure of the eye(s).

    摘要: A system for measuring at least one parameter of an eye. The system includes a probe detachably arranged within a housing, wherein the probe is operable to impact a surface of the eye with a predefined impact attribute, at least one coil operable to maintain the probe within the housing, to release the probe towards the surface of the eye and to retract the probe into the housing, a probe vibration means operable to induce vibration to the probe, a measuring means for measuring a change in vibration of the probe upon impact on the surface of the eye and a controller configured to use the measured change in vibration of the probe to determine the at least one parameter of the eye.

    摘要: A combined intraocular pressure (IOP) measuring and eye medication dispensing device may include a first micro-electro-mechanical-system (MEMS) sensor to generate IOP measurements of a living organism's eye; a medication dispensing device to dispense medication into the living organism's eye; a second MEMS micro-dispenser to interface with the medication dispensing device and to control the dispensing of the medication into the living organism's eye; and an analog-to-digital (A-to-D) converter to receive control signals. The A-to-D converter may communicate the control signals to the first MEMS sensor or the second MEMS micro-dispenser; receive the generated IOP measurements from the first MEMS sensor; receive medication dispensing parameters from the second MEMS micro-dispenser or medication dispensing device, and communicate the generated IOP measurements or the medication dispensing parameters. The device may also include a communications interface to receive the control signals from one or more processors in an external control module.
