Abstract

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.

Claims (16)

1. An article of manufacture comprising a microprocessor and a computer readable medium comprising computer readable program code disposed therein for determining ocular motor function in a patient, the computer readable program code comprising a series of computer readable program steps to effect:

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 receiving 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 article of manufacture of claim 1 , further comprising a series of computer readable program steps to effect, for each value of (i), determining an (i)th horizontal deviation angle.

3. The article of manufacture of claim 1 , further comprising a series of computer readable program steps to effect, for all values of (i), determining an (i)th vertical deviation angle.

4. The article of manufacture of claim 2 , further comprising a series of computer readable program steps to effect, for each value of (i), transforming an (i)th screen image into an (i)th corrected screen image using the (i)th orientation angle.

5. The article of manufacture of claim 3 , further comprising a series of computer readable program steps to effect transforming (N) corrected screen images into a transformed ocular motor function map.

6. A computer program product encoded in a computer readable medium, the computer program product being useable with a programmable computer processor for determining ocular motor function in a patient, the computer program product comprising:

computer readable program code which causes the programmable processor to activate, 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);

computer readable program code which causes the programmable processor to, for each value of (i), synchronously receive 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

computer readable program code which causes the programmable processor to transform (N) screen images into an ocular motor function map.

7. The computer program product of claim 6 , further comprising computer readable program code which causes the programmable processor to, for each value of (i), determine an (i)th horizontal deviation angle.

8. The computer program product of claim 6 , further comprising computer readable program code which causes the programmable processor to, for each value of (i), determine an (i)th vertical deviation angle.

9. The computer program product of claim 6 , further comprising computer readable program code which causes the programmable processor to, for each value of (i), transform an (i)th screen image into an (i)th corrected screen image using the (i)th horizontal deviation angle.

10. The computer program product of claim 9 , further comprising computer readable program code which causes the programmable processor to transform (N) corrected screen images into a transformed ocular motor function map.
