Abstract
A system, method and computer readable medium for efficiently screening patients for glaucoma is disclosed. The method includes attaching electrodes to a patient for measuring the response to stimulus. Then, a first set of stimuli patterns is presented on a display and a first set of signals from the electrodes is received. Then, a second set of stimuli patterns is presented on a display and a second set of signals from the electrodes is received. Next, the first set of signals is averaged with the second set of signals to produce a source data set. The source data set is compared with control data. Finally, using the information from the comparing step, it is determined whether the patient is afflicted with glaucoma.
Claims23
A glaucoma screening method for detecting glaucoma in a patient, the method comprising:
- attaching a plurality of electrodes to the patient;
- displaying a first set of stimuli patterns to the patient;
- receiving, in response to the first set of stimuli patterns, a first set of signals from the plurality of electrodes;
- processing the first set of signals to produce a source data set;
- comparing the source data set with control data;
- and
- determining whether the patient is afflicted with glaucoma based on the comparing step.
A glaucoma screening system for detecting glaucoma in a patient, comprising:
- a plurality of electrodes for attaching to the patient;
- a display for displaying first and second sets of stimuli patterns viewed by the patient;
- and
- a processor for receiving, in response to the first and second sets of stimuli patterns, first and second sets of signals from the plurality of electrodes, averaging the first set of signals with the second set of signals to produce a source data set and comparing the source data set with control data, wherein the processor is coupled to the plurality of electrodes and the display,
- wherein a resultant value for determining whether the patient is afflicted with glaucoma is produced by the processor after comparing the source data set with the control data.
A computer readable medium comprising computer instructions for glaucoma screening in a patient, the computer instructions including instructions for:
- displaying a first set of stimuli patterns to the patient;
- receiving, in response to the first set of stimuli patterns, a first set of signals from a plurality of electrodes attached to the skin on the head of the patient;
- displaying a second set of stimuli patterns to the patient;
- receiving, in response to the second set of stimuli patterns, a second set of signals from the plurality of electrodes;
- averaging the first set of signals with the second set of signals to produce a source data set;
- comparing the source data set with control data;
- and
- determining whether the patient is afflicted with glaucoma based on the instructions for comparing.
