Abstract

Devices and methods to detect the sampling rate of the eye for diagnostic purposes involving: 1) exposing the eye to an analog signal or a digital signal with a varying speed/refresh rate, 2) recording the patient response, either manually or automatically, to detect the speed/refresh rate threshold for aliasing, 3) making a diagnosis with this information and/or correlating this information to a past reading to determine the trend in the function or status of the patient'"'"'s retina, optic nerve or cerebral cortex.

Claims

1. A device for measuring the optical refresh rate of vertebrates, comprising:

An analog or digital optical signal source with a varying speed/refresh rate, and

A detector to determine when the refresh rate has been reached, wherein

The signal source and the detector are both externally applied.

2. The device of claim 1, wherein:

the detector is a manually activated switch that is thrown by the user

3. The device of claim 1, wherein:

the detector automatically detects eye motion

4. The device of claim 3, wherein:

Eye motion is tracked and the presence of certain eye motions indicates the refresh rate

5. The device of claim 3 wherein:

The lack of eye motion indicates that the refresh rate has been reached

6. A method for measuring the optical refresh rate of vertebrates, comprising:

An analog or digital optical signal source with a varying speed/refresh rate, and

A detector to determine when the refresh rate has been reached, wherein

Said refresh rate may be used to monitor or diagnose one or more disorders.

7. The method of claim 6, wherein:

the detector is a manually activated switch that is thrown by the user once the appropriate stimulus is seen

8. The method of claim 6, wherein:

the detector automatically detects eye motion

9. The method of claim 8, wherein:

Eye motion is tracked and the presence of certain eye motions indicates the refresh rate

10. The method of claim 8, wherein:

The lack of eye motion indicates that the refresh rate has been reached

11. The method of claim 6, wherein:

Said disorder may include;

acute or chronic blood glucose control, diabetic neuropathy, multiple sclerosis, glaucoma, optic neuropathy, Guillain-Barre, central nervous system fatigue, concussion, traumatic brain injury and/or any ophthalmic, neurologic, cerebral, autoimmune, vascular or other disorder that may have an impact on the Effective Optical Refresh Rate
