Abstract

The invention discloses a method for measuring lesion characteristics of hypertensive retinopathy. The method comprises the following steps: acquiring a fundus image; recognizing an optic disc region of the fundus image and dividing the fundus image into at least three regions including a first region, a second region and a third region based on the optic disc region; performing artery and vein segmentation on the fundus image by using an arteriovenous segmentation model based on deep learning to obtain arteriovenous segmentation results, wherein the arteriovenous blood vessel marking results include an artery marking result, a vein marking result and a small blood vessel marking result; and based on the three regions and the arteriovenous segmentation result, measuring lesion characteristics in the fundus image, wherein the lesion characteristics comprise at least one of arteriovenous cross-indentation characteristics, arteriovenous local stenosis characteristics and arteriovenous general stenosis characteristics. According to the present disclosure, it is possible to provide a measurement method and a measurement system for efficiently and objectively measuring lesion characteristics of hypertensive retinopathy.

Description

technical field [0001] The present disclosure generally relates to a method and system for measuring lesion characteristics of hypertensive retinopathy. Background technique [0002] The number of hypertensive patients in our country is increasing year by year. At present, there are hundreds of millions of people suffering from high blood pressure. What is even more worrying is that the age of hypertension is getting younger. High blood pressure can easily lead to complications such as myocardial infarction, renal failure, cerebral hemorrhage, cerebral infarction, and uremia, which are life-threatening. Therefore, early identification and intervention of hypertension is of great significance. [0003] Clinically, hypertension can be judged by measuring blood pressure. However, measuring blood pressure is generally unable to assess the patient's recent or long-term hypertension. At present, the lesion characteristics of hypertensive retinopathy (such as arteriovenous cross...
