Abstract: An ophthalmologic information processing device includes a processor and a memory that stores computer-readable instructions. The computer-readable instructions, when executed by the processor, cause the ophthalmologic information processing device to perform processes that include setting a target position on an ocular fundus of a patient's eye, determining a position of one of a ganglion cell corresponding to a photoreceptor cell present at the target position and a photoreceptor cell corresponding to a ganglion cell present at the target position, and obtaining a first analysis result of a retina at the determined position based on one of a second analysis result and a third analysis result. The second analysis result includes an analysis result of the retina at a center point of the determined position and an analysis result of the retina at an auxiliary point. The third analysis result includes an analysis result of the retina in an analysis region.
