An apparatus for automatic adjustment of a treatment of a target person to be treated based on calculated recovery prediction data for predicting a change of a sensory function of said target person in response to said treatment, wherein said recovery prediction data is calculated on the basis of sensory data of said target person and on the basis of sensory data of a reference group of persons treated by said treatment by a processing unit which executes a self-organizing map data mining algorithm, wherein said sensory data comprises global feature data and local feature data and wherein said local feature data relates to a specific spot in a visual field chart of the target person, and wherein said local feature data comprises - neighbourhood data of a spot in a visual field chart of said target person indicating the residual activity and/or its variability in the immediate surrounding of the respective spot, - distance data indicating a distance of a spot in a visual field chart of said target person to a visual field defect border, - a visual field position of a spot in a visual field chart of said target person, and - a residual function value of a spot in a visual field chart of said target person indicating the probability of stimulus detection at the specific spot position, wherein said global feature data comprises - a size of a residual area and a size of a defect area of a sensory organ of said target person, - a reaction time of said target person to a stimulation signal applied to a sensory organ of said target person, - conformity data of a visual field chart of said target person indicating a degree of similarity of the visual field to heminopia and quadrantanopia and - order diffuseness data indicating an extent to which a visual field border of said target person is diffused, wherein said sensory organ is a visual organ of said target person. - neighbourhood data of a spot in a visual field chart of said target person indicating the residual activity and/or its variability in the immediate surrounding of the respective spot, - distance data indicating a distance of a spot in a visual field chart of said target person to a visual field defect border, - a visual field position of a spot in a visual field chart of said target person, and - a residual function value of a spot in a visual field chart of said target person indicating the probability of stimulus detection at the specific spot position, wherein said global feature data comprises - a size of a residual area and a size of a defect area of a sensory organ of said target person, - a reaction time of said target person to a stimulation signal applied to a sensory organ of said target person, - conformity data of a visual field chart of said target person indicating a degree of similarity of the visual field to heminopia and quadrantanopia and - order diffuseness data indicating an extent to which a visual field border of said target person is diffused, - a size of a residual area and a size of a defect area of a sensory organ of said target person, - a reaction time of said target person to a stimulation signal applied to a sensory organ of said target person, - conformity data of a visual field chart of said target person indicating a degree of similarity of the visual field to heminopia and quadrantanopia and - order diffuseness data indicating an extent to which a visual field border of said target person is diffused,
