Figure 1

One retinal artery and one vein seen on spectral domain optical coherence tomography. A. Infrared reflectance image of a retinal artery. B. The same artery shown with optical coherence line scanning. Note: the upper and lower boundary of retinal vessels presented as hyperreflective feature compared to the surrounding retinal tissue (red arrows). C. Infrared reflectance image of a retinal vein. D. The same vein demonstrated with optical coherence scan. Note: the upper and lower boundary did not present different reflectivity compared to the surrounding retinal tissue (white arrows).
