Abstract
A method of using infrared thermal imager to diagnose eye diseases including the dry eye syndromeuses an infrared thermal imager to take the surface image of the eyeball of the patient. Temperature variation at a specific position of the cornea of the eyeball is precisely measured in a unit time. An attenuation coefficient K of a temperature dropping curve and a temperature difference ΔT are obtained from the temperature variation. Optimized curves of K and ΔT are provided for the doctor to diagnose the patient's eye disease.
Claims20
A method of using an infrared thermal imager to diagnose eye diseases, comprising the steps of:
- using the infrared thermal imager to take images of a surface of a cornea and defining at least one temperature measuring point;
- continuously capturing the images of the surface of the cornea within a unit time and obtaining temperature variation data at the temperature measuring point;
- generating a temperature dropping curve according to the temperature variation data and obtaining an attenuation coefficient K;
- and
- computing a temperature difference ΔT within the unit time at the temperature measuring point according to the temperature variation data.
