Method and apparatus for determining ocular motor function
A method and an apparatus are presented for determining ocular motor function in a patient. The patient is instructed to wear a pair of test glasses comprising a first lens having a first color and a second lens having a second color, where the first color and the second color differ. (N) light-emitting devices disposed in a screen are then activated in seriatim, where the (N) light-emitting devices can emit a light comprising the first color and where (N) is greater than 1. (N) images of the screen are synchronously captured upon receiving a signal from the patient indicating an activated light-emitting device is illuminated by a light comprising the second color. Finally, the (N) images are transformed into an ocular motor functioning map.
1. A method of determining ocular motor function in a patient comprising:
instructing the patient to wear a pair of test glasses comprising a first lens having a first color and a second lens having a second color, wherein the first color and the second color differ;
activating, for each value of (i), an (i)th light-emitting device disposed in a screen comprising a total of (N) light emitting devices, wherein the illuminated (i)th light-emitting device emits a light comprising the first color, wherein (N) is greater than 1, and wherein (i) is greater than or equal to 1 and less than or equal to (N);
for each value of (i), synchronously capturing an (i)th screen image upon receiving a signal that the (i)th activated light-emitting device is illuminated by a light comprising the second color; and
transforming (N) screen images into an ocular motor function map.
2. The method of claim 1 , further comprising positioning the patient such that the cranial portion of the patient's sagittal plane is perpendicular to the screen.
3. The method of claim 1 , further comprising, for each value of (i), determining an (i)th horizontal deviation angle.
4. The method of claim 3 , further comprising, for each value of (i), determining an (i)th vertical deviation angle.
5. The method of claim 3 , further comprising, for each values of (i), transforming an (i)th screen image into an (i)th corrected screen image using the (i)th horizontal deviation angle.
6. The method of claim 5 , further comprising transforming (N) corrected screen images into a corrected ocular motor function map.
7. The method of claim 1 , further comprising disposing a camera assembly on the head of the patient.
8. The method of claim 1 , wherein (N) is equal to or greater than two, the method further comprising diagnosing a change in the ocular motor function of a patient.
9. The method of claim 1 , wherein (N) is equal to or greater than four, the method further comprising diagnosing a muscle palsy.
10. A method of determining ocular motor function in a patient comprising:
instructing the patient to wear a pair of test glasses comprising a first lens having a first color and a second lens having a second color, wherein the first color and the second color differ;
projecting, for each value of (i), an (i)th fixation point comprising the first color onto a surface, wherein the (i)th fixation point is one of a (N) fixation points, wherein (N) is greater than 1, and wherein (i) is greater than or equal to 1 and less than or equal to (N).
for each value of (i), synchronously capturing an (i)th image upon receiving a signal that the (i)th activated light-emitting device is illuminated by a light comprising the second color; and
transforming (N) images into an ocular motor function map.
11. The method of claim 10 , further comprising calibrating said projection of the (i)th fixation point.
12. The method of claim 11 , wherein said calibrating further comprises adjusting said projection of the (i)th fixation point based upon a color of the surface.
13. The method of claim 11 , wherein said calibrating further comprises adjusting said projection of the (i)th fixation point based upon a texture of the surface.
14. The method of claim 11 , wherein said calibrating further comprises adjusting said projection of the (i)th fixation point based upon a planarity of the surface.
15. The method of claim 11 , wherein said projecting further comprises using a projector, wherein the projector comprises a battery, wherein said calibrating further comprises adjusting said projection of the (i)th fixation point based upon a charge of the battery.
