1. A method of diagnosing a patient, comprising:
- obtaining, using a high-resolution digital camera comprising greater than 5-megapixel resolution, a digitized representation at a given instant of a face of the patient;
determining, using a networked processing device, a relative position of a pupil of at least one eye of the patient by using a color or intensity change line between the pupil and an iris associated with the pupil of the patient in the digitized representation;
creating, using the networked processing device, an ovoid shape, the ovoid shape following as close a path as possible to the color or intensity change line between the pupil and the iris associated with the pupil;
inscribing, using the networked processing device, the pupil and ovoid shape in a square;
uniformly, using the networked processing device, scattering pixels over the square, the uniformly scattered pixels being uniformly sized;
determining, using the networked processing device, a ratio of a quantity of pixels disposed inside the ovoid shape to a quantity of pixels disposed inside the square;
determining, using the networked processing device, a deviation of the ovoid shape from a circle based on a deviation of the ratio from pi/4; and
comparing the deviation to a threshold of distortion, and in response to the deviation exceeding the threshold of distortion, outputting a suggestion that the patient is experiencing a medical condition.

Abstract
A prediction, diagnosis, or suggesting of a diagnosis of a psychiatric disorder is made based in embodiments of the disclosed technology by determining a shape of one or both pupils in an image of a patient. Such a diagnosis can be made in real-time by diagnosing the patient, or by viewing a digitized version of the patient'"'"'s face as part of post-processing. By finding a pupil which is ovoid or irregular shape (non-circular) and/or comparing the shape to that of shapes of people with known psychiatric disorders, a diagnosis can be suggested.
