A macular region visual defect index calculation apparatus including: visual field probe screen generating means; fixation image displaying and controlling means; probe region setting means; probe points setting means; visual target displaying and controlling means; first counting means; second detection means; second counting means; and visual defect index calculation means for dividing the number of times counted and stored on a memory device by the second counting means, by the total number counted and stored on a memory device by the first counting means; wherein the probe region being locally set mainly in macular region. So, according to the present invention of a macular region visual defect index calculation apparatus, a ratio of visual defect region to macular region can be calculated as an index, and the degree of visual defect against macular region can be numerically grasped.
