Abstract
An example method for automatically measuring a subject's phoria while the subject fixates on a visual target can include capturing an image of at least one of the subject's eyes using an image capturing device after covering and uncovering the at least one of the subject's eyes. The image can include a reflection of light from at least one of the subject's eyes. The method can also include analyzing the image to identify a position of the reflection of the light within at least one of the subject's eyes, and determining a phoria measurement based on the position of the reflection of the light within at least one of the subject's eyes.

A method for automatically measuring a subject's phoria while the subject fixates on a visual target, comprising:
- covering and uncovering at least one of the subject's eyes;
- capturing a sequence of images of the at least one of the subject's eyes after uncovering the at least one of the subject's eyes using an image capturing device, a first image of the sequence of images including a first reflection of light from the at least one of the subject's eyes and a second image of the sequence of images including a second reflection of light from the at least one of the subject's eyes, wherein the first image and the second image are captured at different times after uncovering the at least one of the subject's eyes;
- comparing a position of the first reflection of the light within the first image of the sequence of images to a position of the second reflection of the light within the second image of the sequence of images to determine a magnitude and a direction of any movement after the at least one of the subject's eyes is uncovered;
- and
- determining a phoria measurement based on the determined magnitude and direction of the movement after the at least one of the subject's eyes is uncovered.
A method for automatically measuring a subject's phoria while the subject fixates on a visual target, comprising:
- covering and uncovering at least one of the subject's eyes;
- illuminating the at least one of the subject's eyes with at least two lights using at least two light sources;
- capturing a sequence of images of the at least one of the subject's eyes after uncovering the at least one of the subject's eyes using an image capturing device, the sequence of images including a first image and a second image including reflections of the at least two lights from at least one of the subject's eyes;
- analyzing the first image and the second image to identify respective positions of the reflections of the at least two lights within the at least one of the subject's eyes;
- and
- determining a phoria measurement based on the respective positions of the reflections of the at least two lights within the at least one of the subject's eyes.
A method for automatically measuring a subject's phoria while the subject fixates on a visual target, comprising:
- covering and uncovering at least one of the subject's eyes;
- capturing a sequence of images of the at least one of the subject's eyes after uncovering the at least one of the subject's eyes using an image capturing device, the sequence of images including a landmark within at least one of the subject's eyes;
- analyzing a first image of the sequence of images and a second image of the sequence of images to identify a position of the landmark within the at least one of the subject's eyes;
- and
- determining a phoria measurement based on a determined magnitude and direction of movement of a position of the landmark within the at least one of the subject's eyes as determined between the first and second images.
