The invention relates to the technical field of fundus detection, in particular to a fundus three-dimensional topography measurement system and method based on human eye dynamic response coding, which can realize novel fundus three-dimensional topography measurement which does not depend on a precise mechanical structure, does not need binocular registration, and is simple to assemble and operate, simple in system and controllable in cost. The dynamic adjustment capability of a crystalline lens of a human eye is used as an imaging driving mechanism, the human eye is guided to continuously adjust the focal length by projecting a dynamic virtual image with far and near changes, a focus stack is generated through coding for three-dimensional reconstruction, finally, a fundus color picture and three-dimensional structure data of the fundus color picture are synchronously obtained, and accurate measurement of the fundus three-dimensional shape is achieved. The method does not need complex registration operation of binocular stereo imaging and image texture dependence during three-dimensional reconstruction, and also does not need complex scanning mechanisms and precision machines of laser scanning ophthalmoscopes, optical coherence tomography and other technologies, so that the system hardware cost and the operation difficulty are reduced, and the method is easier to popularize and apply in basic medical scenes.

The utility model discloses a fundus inspectoscope support with an illumination adjusting function, and relates to the technical field of ophthalmoscopes, the fundus inspectoscope support comprises a tripod leg, a base and an ophthalmoscope frame, the bottom of the tripod leg is provided with an anti-skid pad, the tripod leg is installed on the side surface of a knob, the knob is provided with a rotating head, the upper part of the rotating head is provided with a vertical support rod, and the vertical support rod is provided with an illumination adjusting device. A mounting head is arranged on the vertical supporting rod, a screw rod is mounted on the mounting head, a baffle is mounted at one end of the screw rod, an ophthalmoscope frame is mounted at the other end of the screw rod, a transverse supporting rod is mounted on the side face of the rotating head, and a light supplementing lamp is mounted at the end of the transverse supporting rod. In different use environments, light conditions may differ (e.g., hospital or clinic light intensity and type). According to the utility model, the position and the intensity of the light supplementing lamp are adjusted to ensure that the illumination of the ophthalmoscope reaches the optimal state, so that clear and accurate retina images are provided, and the diagnosis effect is improved.

The application relates to a non-invasive intraorbital pressure absolute value measuring system and method thereof, which comprises a retinal vascular blood pressure meter, an ophthalmoscope, an ultrasonic diagnostic instrument and a processor, and the method comprises the following steps: applying pressure to an eyeball by using the retinal vascular blood pressure meter and measuring intraocular pressure change data; simultaneously observing the change state of a retinal central vein during the pressure application process by using the ophthalmoscope; when the retinal central vein is observed to be sunken by using the ophthalmoscope, recording the intraocular pressure data measured by the retinal vascular blood pressure meter at this time, which is retinal vein pressure data; respectively measuring the optic nerve sheath diameter data at the positions of 0 mm and 3 mm behind the eyeball wall by using the ultrasonic diagnostic instrument; and calculating the intraorbital pressure data by the processor according to the measured retinal vein pressure data, the optic nerve sheath diameter data at the positions of 0 mm and 3 mm behind the eyeball wall. Compared with the prior art, the application can non-invasively and accurately measure the intraorbital pressure data.

A method includes receiving an electronic fundus scan. The method also includes determining retinal disease information based on receiving the electronic fundus scan.
