Abstract
A psychophysical method, system, and apparatuses to characterize visual symptoms. A method may include presenting one or more stimuli to a patient indicating one or more visual symptoms. The patient may produce one or more responses to the stimuli. A determination of a measure of visual symptoms of the patient may be made utilizing a Bayesian method based on the responses.
Claims20
A method of determining visual symptoms of a patient, comprising:
- presenting a first stimulus to a patient indicating one or more visual symptoms;
- receiving a first response to the first stimulus by the patient;
- presenting a second stimulus to the patient indicating one or more visual symptoms;
- receiving a second response to the second stimulus by the patient;
- determining a measure of visual symptoms of the patient utilizing a Bayesian method based on the first response and the second response.

A method of determining visual symptoms of a patient, comprising:
- presenting a stimulus to a patient indicating one or more visual symptoms;
- receiving a response to the stimulus by the patient;
- updating a prior probability of visual symptoms for the patient based on the response;
- and
- determining a measure of visual symptoms of the patient based on the updated prior probability.
2 more elements
A method of determining visual symptoms of a patient, comprising:
- presenting a first stimulus to a patient indicting one or more visual symptoms;
- receiving a first response to the first stimulus by the patient;
- determining, based on the first response, a second stimulus to present to the patient to reduce the expectation value of entropy for patient response;
- presenting the second stimulus to the patient indicting one or more visual symptoms;
- receiving a second response to the second stimulus by the patient;
- and
- determining a measure of visual symptoms of the patient based on the first response and the second response.
