An ophthalmologic disease diagnosis apparatus is an apparatus capable of taking an image of an eye fundus of an eyeball to help medical staff to judge an ophthalmologic disease, and the contents of an eye fundus picture are reference data with the best judging effect of the ophthalmologic disease. At present, various eye photographing devices are available on the market, but the effect is not perfect to show the effect required by eye photographing. The research and development process of the equipment is complex, and the specialty is high; in the development stage, when the stage of clinical trial has not been reached, and in the clinical trial, it is required that the inside of the fundus needs uniform and sufficient-intensity illumination during the camera photographing process to photograph a clear and high-quality picture. An eyeground camera belongs to the field of medical imaging and is used for acquiring an image of retina of a human eye so as to facilitate medical staff to check eyeground diseases or assist the medical staff to judge the state of illness of other organs. Since the blood vessels of the fundus are the only blood vessels that can be directly observed by the human body through the body surface, medical personnel can check whether the optic nerve, retina, choroid and dioptric media of the fundus are diseased or not through the fundus camera, and can diagnose and judge the disease condition of other system diseases through the assistance of the fundus camera, such as screening of retinal pictures to detect cerebral infarction, cerebral hemorrhage, cerebral arteriosclerosis, brain tumors, diabetes, nephropathy, hypertension, retinopathy of prematurity, glaucoma, age-related macular degeneration and the like. Since detection of these diseases earlier is more advantageous for clinical treatment, fundus cameras are widely used for clinical screening of fundus diseases, and are indispensable medical instruments. Although the problem that the eye ground camera needs to be operated and read by professional personnel and cannot be normally used by ordinary people is solved, the eye ground camera cannot well screen the eyes thoroughly and comprehensively, diagnosis of the eye diseases of the patient by a doctor is seriously influenced, the best treatment time of the eyes of the patient is delayed, axial shaking cannot be avoided in a focusing process, and shooting accuracy is reduced. An effective solution to the problems in the related art has not been proposed yet.
