    Comparison of retinal vessel measurements using adaptive optics scanning laser ophthalmoscopy and optical coherence tomography

    Purpose We compared adaptive optics scanning laser ophthalmoscopy (AOSLO) and optical coherence tomography (OCT) vessel caliber measurements. Methods AOSLO videos were acquired from 28 volunteers with healthy eyes. Artery measurements were made 0.5–1 disc diameters away from the optic disc margin. Individual segmented retinal arterial caliber was measured in synchronization with cardiac pulsation and averaged to obtain final horizontal retinal arterial caliber (ACH) and horizontal retinal arterial lumen (ALH). All OCT images were obtained with the Spectralis OCT, a spectral-domain OCT system. Vertical retinal arterial caliber (ACV) and vertical retinal arterial lumen (ALV) were measured on the same ...
