It is method for the retina blood vessel analysis which is based on the digital image and purpose of the device, risk of the individual blood vessel and risk of especially stroke, with a higher reliability, decreasing subjective systematic error and nonsystematic error, in order to be able to decide, when it improves the ability to distinguish healthy blood vessel state and a blood vessel state where it has risk simultaneously, to decrease manual labor, to save time. Are remembered the standard picture in regard to the displacement vector which is decided between the relative pictures which are appraised in regard to the standard picture which is recorded, and, concerning the blood vessel segment blood vessel segmented diameter, type, and picture coordinate of blood vessel are decided concerning the consecutive contiguity blood vessel segment which parallels to the blood vessel part of the measurement zone surrounding the papilla in every blood vessel segment, shift time in regard to the picture which is appraised. Relative measurement is done concerning just the identical blood vessel segment which was already measured with the standard picture. The blood vessel part and correlation of the blood vessel segment for the type of blood vessel are adopted while it is the standard picture karaso. Concerning the blood vessel segment of the standard picture and the relative picture parameter is decided concerning all blood vessel segments which were measured by the data set which is remembered, those spaces for example, change of the blood vessel segmented diameter regarding coordinate as a base in order to display with the transitive picture, is offered the change which was disassembled.デジタル画像に基づいた網膜血管分析のための方法および装置の目的は、個々の血管のリスク、特に脳卒中のリスクを、より高い信頼性で、主観的な系統誤差および偶然誤差を少なくして決定し得るように、健常な血管状態とリスクのある血管状態を区別する能力を向上させると同時に、手動労力を低減し、時間を節約することである。乳頭を取り囲む測定ゾーンの血管部分に沿った一連の隣接血管セグメントについて血管セグメント直径、血管の種類、および画像座標が決定され、血管セグメントごとに、評価される画像に関して、時間をずらして記録される基準画像に関して、および、血管セグメントについて基準画像と評価される比較画像
