Abstract:
A ophthalmologic method and apparatus for processing a captured image of a tear film lipid layer on a cornea of a patient's eye to be examined and for classifying types of dry eye of the patient's eye. The captured image of the tear film lipid layer is processed to measure a movement speed of the tear film lipid layer at the time of opening of the patient's eyelid. The captured image of the tear film lipid layer is further processed to measure a time until the tear film lipid layer is broken up after the patient's eyelid has been opened and a break up region is detected. The type of dry eye of the patient's eye is classified based on the two measurement results.
