Agreement with all 14 objective measures was assessed with correlation/regression analyses. ![]() Interobserver agreement was assessed by using κ statistics. Vessels were graded (from 0 = none to 5 = tortuous) independently by two observers. Retinal digital images were analyzed using the Computer Assisted Image Analysis of the Retina (CAIAR) program, including 14 measures of tortuosity. Cross-sectional study of 387 retinal vessels (193 arterioles, 194 veins) from 28 eyes of 14 children (aged 10 years). To examine the agreement of a novel computer program measuring retinal vessel tortuosity with subjective assessment of tortuosity in school-aged children.
