Evaluation of micrometric and microdensitometric methods for measuring the width of retinal vessel images on fundus photographs

Abstract

The width of retinal vessel images on fundus photographs was determined by projection micrometry and microdensitometry. These methods were evaluated on 12 retinal vessels using the negatives of 570-nm monochromatic fundus photographs. For projection micrometry, the intraobserver reproducibility of vessel width measurements was 1.6%–2.9%, depending upon the… (More)
