METHOD, APPARATUS, COMPUTER PROGRAM, AND COMPUTER READABLE MEDIUM FOR QUANTIFICATION OF RETINAL BLOOD VESSEL TORTUOSITY BY ANALYSING FUNDUS PHOTOGRAPHS

摘要

A method, an apparatus, a computer program, and a computer-readable medium for quantifying retinal blood vessel distortion through fundus photo image analysis are provided. The method for quantifying retinal blood vessels according to the present invention includes the steps of obtaining a fundus photograph image, a reference point on the retinal vessel located at a point separated by a predetermined linear distance d from the starting point of the retinal vessel located at the margin of the optic nerve papilla in the fundus photograph image. The step of specifying the, measuring the length b of the retinal blood vessel from the start point to the reference point in the fundus photograph image, calculating the value obtained by dividing the measured b by d as the flexion index of the retinal blood vessel, and outputting the flexion index Includes. The flexion index derived by the present invention can be used as an auxiliary diagnostic tool in determining the course of retinopathy of prematurity and the timing of treatment.
