1. An opthalmologic information-processing apparatus comprising: an accepting part configured to accent a 3-dimensional image representing a morphology of a retina; a specifying part configured to specify, in the 3-dimensional image, a plurality of positions corresponding to a plurality of stimulation points in a visual-field examination; and an analyzing part configured to analyze the 3-dimensional image and find a layer thickness of the retina at each of the plurality of positions, wherein the specifying part specifies, for each of the plurality of positions, a new position related to the position, wherein the analyzing part analyzes the 3-dimensional image and finds the layer thickness of the retina at the new position, wherein the new position is a position where a ganglion cell, which receives signals from a cone existing at the position, exists, wherein the specifying part comprises a storing part configured to previously store association information that associates a position of a cone and a position of a ganglion cell, and wherein the specifying part refers to the association information, for each of the plurality of positions, and finds the position of the ganglion cell corresponding to the position of the cone, as the new position.
