Methods and systems for diagnosing eyes using ultrasound
Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user's body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.
1. A wearable augmented reality device comprising:
an augmented reality head-mounted ophthalmic system comprising:
an augmented reality display platform comprising a display configured for forming an image viewable by the wearer, the display comprising a plurality of waveguides configured to pass light from the world into an eye of a wearer wearing the head-mounted system, wherein each waveguide comprises:
in-coupling diffractive optical elements configured to in-couple light into the waveguide; and
out-coupling diffractive optical elements configured to out-couple light propagating within the waveguide,
wherein out-coupling diffractive optical elements of some waveguides of the plurality of waveguides are configured to output light with different wavefront divergence than other waveguides of the plurality of waveguides;
a camera configured to image the eye and detect vision abnormalities;
an ultrasound transmitter configured to deliver ultrasound to the user's eye; and
an ultrasound receiver configured to receive sound reflected from the user's eye to create an ultrasound image,
wherein the augmented reality head-mounted ophthalmic system is configured to conduct an ultrasound examination after detecting vision abnormalities in the wearer.
2. The device of claim 1 , wherein the wearable augmented reality system is configured to detect eye abnormalities or to monitor health of the user's eye from the created ultrasound image.
3. The device of claim 2 , further comprising a processor configured to match features in the ultrasound image with images stored in the device to detect eye abnormalities.
4. The device of claim 1 , wherein the ultrasound transmitter is configured to deliver ultrasound based on a protocol unique for the wearer.

6. The device of claim 5 , wherein the adaptable optics element comprises a variable focus element.
7. The device of claim 6 , wherein the variable focus element comprises a membrane mirror.
8. The device of claim 7 , wherein the display platform comprises:
one or more electrodes coupled to the membrane mirror; and
a control system configured to selectively control the one or more electrodes to modify a shape of the membrane mirror.
9. The device of claim 1 , wherein the display comprises a fiber scanning display.
10. The device of claim 1 , wherein the ultrasound transmitter and receiver are part of an ultrasound probe.
11. A wearable augmented reality device comprising:
an augmented reality head-mounted ophthalmic system comprising:
an augmented reality display platform comprising a display configured for forming an image viewable by the wearer, the display comprising a plurality of waveguides configured to pass light from the world into an eye of a wearer wearing the head-mounted ophthalmic system, wherein each waveguide comprises:
in-coupling diffractive optical elements configured to in-couple light into the waveguide; and
out-coupling diffractive optical elements configured to out-couple light propagating within the waveguide,
wherein some waveguides of the plurality of waveguides are configured to output light with different wavefront divergence than other waveguides of the plurality of waveguides;
a camera configured to image the eye and detect vision abnormalities;
an ultrasound transmitter configured to deliver ultrasound to the user's eye; and
an ultrasound receiver configured to receive sound reflected from the user's eye to create an ultrasound image,
wherein the augmented reality head-mounted ophthalmic system is configured to conduct an ultrasound examination after detecting vision abnormalities in the wearer,
wherein the wearable augmented reality device is configured to measure a response of the user's eye to the ultrasound to detect eye abnormalities.
12. The device of claim 11 , wherein the abnormality includes a detached retina.
13. The device of claim 11 , wherein the display platform comprises an adaptable optics element configured to output light, for forming the image, to a selected portion of the wearer's eye.
14. The device of claim 13 , wherein the adaptable optics element comprises a variable focus element.
15. The device of claim 14 , wherein the variable focus element comprises a membrane mirror.
16. The device of claim 15 , wherein the display platform comprises:
one or more electrodes coupled to the membrane mirror; and
a control system configured to selectively control the one or more electrodes to modify a shape of the membrane mirror.
