The present patent application discloses a digital slit-lamp microscope system and the methods of the electronic recording and remote diagnosis. The present patent application relates to the field of optical instrument and remote communication control. The purpose is to solve the problems of the electronic recording, reappearing and remote diagnosis of the slit-lamp image. The digital slit-lamp microscope system comprises digital slit-lamp microscope side, communication unit and client side. The digital slit-lamp microscope side includes a build-in slit-lamp microscope and is connected to the communication unit and the client side in sequence. The digital slit-lamp microscope side irradiates the eyes of the patient, and then transmits the pathology information of the eyes of the patient to the communication unit and the client side in sequence. The client side remote process and reappear the pathology information of the eyes of the patient in form of image. The client side remote controls the digital slit-lamp microscope side by the communication unit to collect the optical information of the eyes of the patient. The present patent application is used in the electronic recording, reappearing and remote diagnosis of the slit-lamp image.
