  • Publication number: 20210366612
    Abstract: A method used for supporting ophthalmic examinations includes the step of preparing association information between medical information items and ophthalmic examination conditions. Patient information of a patient is transmitted from a client to a server configured to store and manage medical information. The server retrieves medical information of the patient based on the transmitted patient information, acquires a condition corresponding to the retrieved medical information from the association information, and transmits the acquired condition to the client. The client acquires examination data from the patient's eye based on the transmitted condition, and transmits the examination data together with the patient's patient information to the server. The server stores the transmitted examination data and/or an analysis result thereof.
