Description

Full-automatic multispectral fundus camera

Technical Field

The utility model relates to an ophthalmology technical field particularly, relates to a multispectral eye ground camera of full-automatic formula.

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. Direct or indirect visual observation under a fundoscope or film reading observation after fundus color photography is simple and convenient, but the pathological changes of deep tissues (such as choroid) are difficult to observe through superficial tissues by flesh eyes or photos, and the diagnosis accuracy is greatly influenced by the self experience of an inspector. For some fundus diseases, such as choroidal retinal neovascularization (CNV), the geometric form of the fundus tissue change caused by the CNV is usually not obviously changed on the same color image, so that the discrimination of the neovascularization by single fundus color photograph is difficult. The resolution ratio of observation of local fundus tissues can reach 5um by an optical coherence tomography scanner, a retina thickness analyzer and the like. However, the observation range is generally limited in the limited region at the back, the whole observation is difficult to realize in the linear scanning mode, and the difficulty in differential diagnosis of lesions such as new vessels is high. In addition, when there is a bleeding lesion on the retinal surface, retinal and choroidal lesions under bleeding cannot be clearly observed. High cost and complex operation. An effective solution to the problems in the related art has not been proposed yet.
