Abstract: Disclosed is a fluorescent fundus camera which is one kind of ophthalmological diagnostic equipment, using a blue excitation light beam when a contrast medium appears in the retinal vessels. When an abnormal blood vessel is present, the contrast medium leaks into the retina or appears as color in tissues surrounding the retina, and the presence of damage to the retina and the appearance of abnormal neovascularization can be found.

Abstract: Disclosed are an algorithm for automatic fundus image reading, and a deep learning architecture for automatic fundus image reading, which are capable of minimizing the amount of data required for learning by training and reading artificial intelligence in a manner similar to that of an ophthalmologist who acquires medical knowledge.

Abstract: Disclosed is a polarization fundus camera including: an illumination unit emitting light; a diffusion lens; an illumination lens irradiating the light introduced from the diffusion lens; a mirror reflecting light introduced from the illumination lens; a polarization beam splitter; an objective lens enlarging an image of a fundus formed by the light introduced from the polarization beam splitter; a short-range eyepiece lens reducing an image of the fundus enlarged by the objective lens; a linear polarization filter; a narrowband optical filter; and an imaging device.

Abstract: Disclosed is a coaxial non-mydriatic multispectral fundus camera, including: an illumination unit configured to emit light; a diffusion lens configured to diffuse the light incident from the illumination unit; an illumination lens configured to irradiate the light incident from the diffusion lens at a predetermined emission angle; a mirror configured to reflect the light incident from the illumination lens; a polarizing beam splitter configured to transmit P-polarized light of the light incident from the mirror and reflect S-polarized light thereof; an objective lens configured to image a fundus using the light incident from the polarizing beam splitter and then enlarge a returning image of the fundus; a short-range eyepiece lens configured to reduce or enlarge the image of the fundus enlarged by the objective lens; and an imaging device configured to acquire a fundus photograph from the image of the fundus received from the short-range eyepiece lens.
