Method and system for analyzing hypertension retinal vessel change characteristic data

Abstract

The invention relates to the technical field of image analysis, health service and data processing, and provides a method for analyzing the hypertension retinal vessel change characteristic data. Themethod includes: obtaining the fundus image of the patient; extracting and identifying the retinal vessel change characteristic data of a fundus image of a patient, wherein retinal vessel change characteristics comprise limitation retinal artery constriction; analyzing and comparing the retinal vessel change characteristic data of the patient in different periods; further obtaining the change condition of the fundus screening characteristic data of the patient; analyzing blood pressure control of the patient in a near period and related prevention and treatment effect conditions of hypertension. A powerful excitation mechanism is provided for enhancing the compliance of basic treatment intervened by the lifestyle of a patient, a user is greatly helped to detect and control the blood pressure consciously and regularly, and the method has important significance in treatment effect evaluation and chronic disease management of hypertension.

Description

technical field [0001] The invention relates to the technical fields of image analysis, health service and data processing, in particular to a method and system for analyzing characteristic data of retinal blood vessel changes in hypertension. Background technique [0002] According to the latest results of a sample survey of hypertension in my country, there are about 250 million hypertensive patients in China, and the prevalence rate is on the rise, and it increases with age. It is also a comorbidity of many diabetic patients. 1 person suffers from high blood pressure. Although the awareness rate and control rate of hypertension have been increasing over the years, compared with the data from 2002 to 2015, the awareness rate has increased from 30.2% to 42.7%, and the treatment rate has increased from 24.6% to 38.3%. But the control rate is still less than 14.5%. [0003] As early as 1975, Goto et al.'s research confirmed that the fundus circulation and intracranial blood ve...

Problems solved by technology

[0011] However, due to the lack of incentives or methods for the most important or necessary lifestyle intervention basic treatments such as diet and exercise, the patient's compliance is low, and it is difficult to achieve the effect of lifestyle intervention basic treatment

Generally, early-stage hypertensive patients and a large number of type 2 diabetic patients do not feel it before their blood pressure is greater than 120 / 80mmHg, less than 140 / 90mmHg, or even serious complications occur, and it is difficult to consciously achieve regular self-blood pressure monitor or measure
