Abstract
A patient's visual motion detection threshold is measured by displaying on a display screen a fixation target on a background image. The characteristics of a threshold wave pattern displayed against the background image is adjusted while displaying the fixation target. An indication is received when the threshold wave pattern becomes visible to the patient while adjusting the characteristics of the threshold wave pattern. The patient's measured visual motion detection threshold is established based on receiving the indication.
Claims31
A method comprising executing computer program instructions to measure a patient's visual motion detection threshold by:
- displaying on a display screen a fixation target on a background image;
- adjusting characteristics of a threshold wave pattern displayed against the background image while displaying the fixation target;
- receiving an indication when the threshold wave pattern becomes visible to the patient while adjusting the characteristics of the threshold wave pattern;
- and
- establishing the patient's measured visual motion detection threshold based on receiving the indication.
A system for measuring a patient's visual motion detection threshold, the system comprising:
- non-transitory memory storing computer program instructions;
- at least one processor that executes the computer program instructions to:
- display on a display screen a fixation target on a background image;
- adjust characteristics of a threshold wave pattern displayed against the background image while displaying the fixation target;
- receive an indication when the threshold wave pattern becomes visible to the patient while adjusting the characteristics of the threshold wave pattern;
- and
- establish the patient's measured visual motion detection threshold based on receiving the indication.
An apparatus for measuring a patient's visual motion detection threshold, the apparatus comprising a display screen and a patient input device in communication with non-transitory memory storing computer program instructions and at least one processor that executes the computer program instructions to:
- display on the display screen a fixation target on a background image;
- adjust characteristics of a threshold wave pattern displayed against the background image while displaying the fixation target;
- receive an indication from the patient input device when the threshold wave pattern becomes visible to the patient while adjusting the characteristics of the threshold wave pattern;
- and
- establish the patient's measured visual motion detection threshold based on receiving the indication.
