Description

Multimode fundus camera

Technical Field

The utility model relates to an ophthalmology technical field particularly, relates to a multimode eye ground camera.

Background

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 refraction medium of the fundus have pathological changes through the fundus camera, and can also assist in diagnosing and judging the disease conditions of other system diseases through the fundus camera, for example, screening 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 the earlier detection of these diseases is more advantageous for clinical treatment, fundus cameras are widely used for clinical screening of fundus diseases, and are indispensable medical instruments. Fundus camera optical path design typically includes the following components: fundus photographic optical paths (illumination and imaging optical paths) are usually added with a vision fixation target optical path and an iris photographic optical path for obtaining stable high-quality pictures, wherein the vision fixation target optical path is fixed in a certain specific direction for the eye to be detected to watch, and the iris photographic optical path is mainly used for determining the direction of the eye to be detected so as to adjust equipment to align the eye to be detected. Some devices, in order to reduce cost, may not include a vision fixation target optical path, and may operate to fix the patient's eye in front or in a certain direction, or may not include an iris photography optical path, and may use the fundus photography optical path to locate the initial position of the eye by changing the focal length of the combined lens. The quality of pictures shot by the existing fundus camera is low, the detected precision and result have certain deviation, the operation is difficult, the patient is uncomfortable to detect, and the use of people is not facilitated. An effective solution to the problems in the related art has not been proposed yet.
