The invention relates to a diabetic retinopathy fundus photography grading report system combined with a clinical guide, based on an artificial intelligence deep learning technology, and belongs to the field of fundus lesion analysis. The system accurately identifies and segments various lesions such as microhemangioma, bleeding, exudation and the like and symbolic structures such as optic discs, macular regions and the like by automatically analyzing fundus photographic images. The system adopts ICDR international standards to grade diabetic retinopathy, and provides diagnosis and treatment suggestions for lesion characteristics in combination with clinical guidelines of American ophthalmology institute in 2019. Through big data training, the system can generate detailed reports in real time, the early screening rate is remarkably improved, misdiagnosis and missed diagnosis are reduced, and the diagnosis speed and accuracy are improved. The system comprises a plurality of modules, such as an image pre-classification module, a deep learning focus recognition module, an ICDR grading module and a report generation module, efficient and accurate diabetic retinopathy diagnosis and grading are cooperatively achieved, and the clinical management level is improved.

The invention provides eye adjusting equipment integrating eyelid opening, fundus photography and a data port, and belongs to the technical field of intelligent medical wearable equipment. The equipment comprises a glasses frame main body, a non-invasive eyelid opening mechanism, a high-resolution fundus photographing module, diopter-adjustable lenses, a data processing unit and a wired and wireless data port. The eyelid opening mechanism adopts a medical silica gel flexible opening sheet and a push rod, so that safe and automatic eyelid separation is realized; the fundus photographing module supports clear imaging at a field angle of 30-50 degrees based on infrared illumination and a CMOS sensor, and has pupil tracking and automatic focusing functions; the built-in electric control zoom lens can dynamically adjust the diopter from 6.0 D to + 4.0 D. The problems that existing fundus examination equipment is large in size, complex to operate, serious in eyelid shielding, unable to use and the like are solved, and the fundus examination equipment has remarkable clinical application value and industrialization prospects.

The invention discloses an ophthalmology intelligent auxiliary diagnosis method and system based on heterogeneous data collaboration, and the method comprises the steps: synchronously obtaining an ophthalmology multi-mode heterogeneous data set of a patient, including an OCT image, a fundus photograph and a visual field inspection report; the OCT image is subjected to retina layered structure segmentation, and an RNFL thickness distribution diagram is extracted; performing optic disc region positioning and blood vessel tree segmentation on the fundus photography to generate a CDR and a blood vessel curvature quantized value; mode deviation probability graph coding is carried out on the visual field inspection report, and a quadrant sensitivity missing matrix is output; an ophthalmic multimodal heterogeneous data set is associated through a patient unique identifier, and a RNFL thickness distribution map of OCT is mapped to an optic disc coordinate system of fundus photography by using feature-driven non-rigid registration. According to the invention, an ophthalmology multi-modal data cooperation barrier is broken through, an intelligent decision-making system with structure-function mutual verification is constructed, and the diagnosis reliability and clinical interpretability are significantly improved.
