Abstract
A system and method for detecting a stroke includes a non-contact ocular pulse measurement device configured to output a first and a second ocular pulse measurement signals for each of a patient's eyes, respectively. A computing system has a processor and a memory, and the memory stores instructions that when executed cause the processor to analyze the first and second ocular pulse measurements. An index of difference between the first and second ocular pulse measurements is determined, and a user interface is generated that includes a stroke advisory to the patient based on the index of difference.

A system for detecting a stroke, comprising:
- a non-contact ocular pulse measurement device configured to output a first and a second ocular pulse measurement signals for each of a patient's eyes, respectively;
- a processor and a memory, the memory storing instructions that when executed cause the processor to
- analyze the first and second ocular pulse measurements;
- determine an index of difference between the first and second ocular pulse measurements;
- and
- generate a user interface including a stroke advisory to the patient based on the index of difference.
A method for detecting a stroke, comprising:
- measuring an ocular pulse for two eyes of a patient using a non-contact measurement;
- comparing the measured ocular pulse between the two eyes;
- generating a user interface including a stroke advisory to the patient based on the comparison.
