Claim Text:
1. A method of ophthalmological image analysis, comprising: a step of designating an area to be analyzed in a photographed image of an eyelid of an eye; a step of extracting Meibomian-gland subareas that represent Meibomian glands in the eyelid, on the basis of the luminance value of each pixel in the area being analyzed; a step of specifying vertices for the Meibomian-gland subareas, and on the basis of the vertices, specifying a boundary that divides the area being analyzed into the Meibomian-gland subareas with the inter-Meibomian gland subareas, which are subareas that exist between the Meibomian-gland subareas, and into the other remaining external subareas; and a step of dividing the sum of the surface area of the Meibomian-gland subareas and the surface area of the inter-Meibomian gland subareas by the surface area of the area being analyzed, calculating the quotient, which represents occupancy ratio as distribution information of Meibomian glands in the area being analyzed.
