PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus whose units can be easily replaced, so as to improve its measurement and analytical levels easily.SOLUTION: The ophthalmologic apparatus to analyze ocular characteristics of a subjects eye includes: a measurement unit for measuring or examining the subjects eye an imaging unit for obtaining image of the subjects eye a moving mechanism unit for moving the measurement unit for alignment a control unit for controlling a drive of the moving mechanism unit based on the image an analysis unit for obtaining analytical data on the ocular characteristics of the subject by analyzing the image and a monitor for displaying at least either the image or the analytical data. The control unit includes a first image-producing unit for transmitting the image to the monitor. The analysis unit includes a second image-producing unit for transmitting the image including the analytical data to the monitor. The apparatus also includes a display selection unit for selecting either of the images from the image-producing units for display on the monitor.
