Retinopathy evaluation model establishing method and system

Abstract

The invention discloses a retinopathy evaluation model establishing method. The method comprises the steps: enabling a retinopathy evaluation model building system to carry out the image correction ofa plurality of stored retinopathy images, so as to obtain a plurality of corrected images, enabling each retinopathy image to be corresponding to a lesion severity level, and enabling the corrected images to be grouped into a training subset, a verification subset and a test subset, and establishing a retinopathy evaluation model according to each corrected image in the training subset and the corresponding lesion severity level thereof, and each corrected image in the verification subset and the corresponding lesion severity level thereof, and finally detecting the accuracy of the retinopathy evaluation model according to the test subset. In addition, the invention further provides a retinopathy evaluation model establishing system.

Description

technical field [0001] The invention relates to a method for establishing an evaluation model, in particular to a method and system for establishing a retinopathy evaluation model. Background technique [0002] Diabetes is a disease in which blood sugar rises due to insulin deficiency or factors that antagonize insulin function, and long-term rise in blood sugar can cause microvascular lesions in the retina of the eye, called Diabetic retinopathy (Diabetic retinopathy). [0003] Most of the type 1 (insulin-dependent IDDM) diabetic patients will develop retinopathy after 15 to 20 years of illness, and 20% to 30% of them will lead to blindness; while type 2 (non-insulin dependent IDDM) Type NIDDM) diabetic patients will have more than 60% chance of developing retinopathy. [0004] The true pathogenic mechanism of diabetic retinopathy is still not very clear, but it is basically known that long-term elevated blood sugar will lead to increased platelet aggregation and damage to...

Problems solved by technology

[0006] However, when doctors evaluate and grade based on ophthalmoscope medical images, they are based on their experience, and there may be slight differences in the grades of evaluation among different doctors. Level 4, doctors in another regional hospital may judge it as level 5. Therefore, there is no set of precise standards for the assessment and grading of diabetic retinopathy, and the assessment of retinopathy by doctors is not objective enough. Patients may have a negative impact on
