Methods, apparatus, and systems for ophthalmic testing and measurement

1. A device for administering an ophthalmic test to a test subject, the device comprising:

a wearable frame configured to optically couple an eye of the test subject to an image plane presented to the eye via the wearable frame;

a light source disposed in the wearable frame;

a processor coupled to the light source and the wearable frame;

a memory coupled to the processor; and

one or more computer programs stored in the memory and configured to be executed by the processor, the one or more programs including instructions that upon execution:

control the light source to generate a fixation light and present a fixation point within the image plane, the fixation point being configured for focusing attention of the test subject during the ophthalmic test;

generate a first audible command, via the wearable frame, to instruct the test subject to focus her gaze on the fixation point;

control the light source to generate a stimulus light and present a stimulus area within the image plane;

generate a second audible command, via the wearable frame, to instruct the test subject to provide one or more psychophysical responses indicating observation of the stimulus light;

receive the one or more psychophysical responses indicating observation of the stimulus light from the test subject;

analyze the one or more psychophysical responses to determine whether the test subject requires guidance to complete the ophthalmic test; and

in an event the test subject requires guidance, provide the test subject with additional audible commands via the wearable frame, wherein the additional audible commands comprise: continuing to focus gaze, continuing to provide psychophysical responses, and keeping the eye open.

2. The device of claim 1 , further comprising an audio speaker configured to provide the first, second, and additional audible commands via the wearable frame.

3. The device of claim 2 , wherein the one or more programs further comprise instructions that upon execution provide the test subject with introductory information regarding the test.

4. The device of claim 3 , wherein the introductory information comprises an audible message greeting the test subject.

5. The device of claim 4 , wherein the ophthalmic test comprises a visual field test.

6. The device of claim 4 , wherein the ophthalmic test comprises a dark adaptation test.

7. The device of claim 6 , wherein the one or more programs further comprise instructions that upon execution control the light source to generate a photobleaching light configured to photobleach a photopigment of the eye.

8. The device of claim 7 , wherein the photobleaching light comprises a light within a green spectrum.

9. The device of claim 8 , wherein the stimulus light is configured to stimulate the eye after photobleaching with the photobleaching light.

10. The device of claim 9 , wherein the photobleaching light is presented in a photobleaching area within the image plane.

11. The device of claim 10 , further comprising a light seal configured to minimize passage of ambient light to the eye.

12. The device of claim 11 , wherein the light seal comprises a conformable body having at least one opening configured to be substantially aligned with the eye.

13. The device of claim 12 , wherein the light seal is removably coupled to the wearable frame such that upon coupling of the conformable body with the wearable frame, a combination of the conformable body and the wearable frame minimizes the passage of ambient light to the eye.

14. The device of claim 13 , wherein the light seal comprises a material having one or more fibers.

15. The device of claim 14 , wherein the light source comprises laser light.
