Comparison of Common Retinal Vessel Caliber Measurement Software and a Conversion Algorithm

To compare three commonly used retinal vessel caliber measurement software systems, and propose an algorithm for conversion between measurement systems.We used 120 retinal photographs to evaluate the agreement between three commonly used software (Retinal Analysis [RA], Integrative Vessel Analysis [IVAN], and Singapore I Vessel Assessment [SIVA]). Bland-Altman plots were used to evaluate agreement of retinal arteriolar (central retinal artery...
